Flying a drone in congested urban centres is tricky.

Not only does the operator have to be aware of buildings, low-flying helicopters and people and property on the ground, but on many days there’s an unseen force at work that can cause havoc for safe RPAS flight: Wind. Specifically, the turbulence, wind tunnels and even wind shear that can be created when wind passes between and over buildings.

“Urban environments create a variety of exacerbated micro-level wind effects including shear, turbulence and eddies around buildings. These effects can locally increase reported wind speeds by up to 50 per cent,” says Dr. Eric Saczuk, InDro’s Flight Operations Lead and head of RPAS Operations at the BC Institute of Technology.

Routine drone flights in dense urban centres are clearly part of the future. That’s why a long-term study into how wind behaves in such settings has been underway, with funding from the Transport Canada RPAS Task Force (now absorbed into a broader Strategy and Emerging Technologies (SET) Branch and the National Research Council (NRC) Integrated Aerial Mobility Program. Now, a scientific research paper has been published on the preliminary findings – with more research to come.

And the InDro connection? InDro Chief Pilot Dr. Saczuk has been overseeing these flights – with more to come on the immediate horizon. On previous missions, the drone was equipped with an AVSS parachute and a wishbone-like device that carried two precision sonic anemometers positioned to capture windspeed data from different angles. That georeferenced data determines not only the speed and turbulence of the wind, but also the precise direction (and changes in direction, including wind shear) as the drone passes over what could be called an urban wind canyon.

THE RESEARCH – AND THE PAPER

 

The first phase of this ongoing project involved two very distinct procedures. One involved the drone flights, which included not only navigating wind-tunnel corridors in urban Montreal, but also hovering for periods at specific spots over and adjacent to buildings. Separate anemometers were affixed to the buildings themselves and the data was compared.

The second part took place in the NRC’s wind tunnel. There, a 1:300 scale model of the urban environment the drone flew in was assembled and placed in the tunnel. Measurements were made at various controlled windspeeds. The data from each was then compared for consistency.

The ultimate goal, for this phase of the research, is to be determine whether accurate predictive analytic models could be created that could be used when planning RPAS flights. The research might uncover, for instance, that general wind speeds within the flight parameters of a given RPAS might exceed those limits when passing around and over buildings, resulting in turbulence that would be unsafe for a mission to proceed. Such models will be immensely useful as urban RPAS flights become more routine.

But the first phase was simply to see if the data captured by the drone was in sync with the data produced in the wind tunnel testing.

“The goal of the overall study was to acquire urban-airflow data in a real environment in order to validate equivalent airflow characteristics from model-scale testing,” states the paper.

“The field test was designed to measure urban airflow characteristics using anemometers mounted on a small RPAS. The RPAS was flown along various flight paths in downtown Montréal in 2023. Following the field test, airflow measurements were taken at the equivalent spatial locations in a wind tunnel using a 1:300-scale model of the same test site. Data-processing routines for the RPAS airflow measurements included accounting for the body-motion of the vehicle and applying custom calibration equations for the RPAS-mounted sonic anemometers.”

 

THE RESULTS

 

The data obtained by the drone compared favourably with the scale-model tests carried out in the wind tunnel. In other words, the data indicates it may be possible to produce reliable, predictive models of various urban centres by testing scale models within the wind tunnel itself. Eventually, this research could potentially indicate specific locations in cities where turbulence is of particular concern for RPAS flights.

As the report states: “The distribution of mean flow speed and turbulence intensity from the field test compared well with the wind-tunnel results, including the shape of the distribution and location of the maxima. Additionally, the variation in flow characteristics along a flight path, such as mean flow speed and turbulence intensity, compared favourably with wind-tunnel results acquired at the same relative locations. This work demonstrates the suitability of model-scale testing for studying urban flow fields.”

INDRO’S TAKE

 

This is complex research, and these are complex missions to fly. We are pleased to have other partners on board in this research, including McGill University, Place Ville Marie, Îlot Balmoral, Maison du Développement Durable, Hôpital général de Montréal, and the Centre Hospitalier de l’Université de Montréal.

“InDro is pleased to be part of this critical research, which will help ensure safe flights in turbulent urban environments – including models that may one day predict when and where it’s unsafe to carry out missions,” says InDro Founder and CEO Philip Reece. “Of course, there are other challenges flying in cities – including the potential impact of a constellation of RF signals that could interfere with C2 links. We look forward to the next phase of this project.”

This research is ongoing and we have more flights planned in Montreal later in September.

It’s also worth noting we have barely scratched the surface of this exhaustive research paper. For those interested in a more in-depth explanation – along with plenty of data visualisations – you’ll find it here. You can also check out our 2023 flight in this post.

What Canada’s new drone regulations mean for you

What Canada’s new drone regulations mean for you

Mar 27, 2025 | Drone News, InDro News, Kate Klassen, Transport Canada

By Kate Klassen, Training and Regulatory Specialist

 

It’s not every day I get excited to see an email before 0600. But yesterday, March 26, was one of those days! 

Unexpectedly, Transport Canada announced the publication of the highly anticipated Canada Gazette II which included new regulations for RPAS Operations Beyond Visual Line-of-Sight and Other Operations.  

It’s a hefty publication with lots of cross-references and makes for a bit of a dense read. But after a day of reading, re-reading, digesting and consulting with other colleagues who share my nerdiness about this area, I’m pleased to provide this overview – which we’ll continue to update as new information becomes available.  

All-in-all, it’s what we were expecting and hoping to see: Common-sense amendments to existing regulations, noticeable inclusions from feedback on the Canada Gazette I draft, and formalization of the next phase of routine RPAS operations in Canada.  

If you were one of the many who took the time to provide comments to Transport Canada following CG1, well done. What we saw today is proof they listen and that those efforts matter. Thank you, TC! 

Some regulations come into effect on April 1 2025, with others commencing November 4, 2025. This phased approach enables the mechanisms for compliance to be in place prior to requiring compliance with them. In other words, it gives you time to get prepared before it’s required by law. So don’t panic. There are no major changes required before this flying season. You can’t even fly BVLOS under these rules until November.

Now, let’s dive in. 

Below: Low-risk BVLOS flights will be permitted starting November 4, 2025. These operations will require a new Level 1 Complex RPAS Certificate

 

PRACTICALLY SPEAKING

 

As mentioned, the document published yesterday is complex. Our goal here is explain what it actually means in the real world. So we’re going to break this down into implications for different scenarios. Here’s what the new rules mean for RPAS pilots with: 

 

…a sub-250 gram drone
  • On April 1, there are more regulations than just the CAR 900.06 ‘don’t be an idiot’ rule that come into force. These specifically spell out steps to follow if you inadvertently enter restricted airspace (CAR 900.07) and include prohibitions around emergency security perimeters (CAR 900.08) 
…a Basic RPAS Certificate
  • Not many changes aside from general tidying of rules to ensure intent aligns with application 
  • You can allow a non-certified individual to fly under your supervision (CAR 901.54) 
  • You are qualified as a visual observer for BVLOS operations 
…an Advanced RPAS Certificate
  • You get new capabilities as of November 4th – and you don’t have to do any additional testing to take advantage of them! 
  • You’ll be able to carry out EVLOS – Extended Visual Line Of Sight operations. This allows you to fly up to 2NM from the pilot, control station and Visual Observer at any time during the flight, provided the pilot and control station are at the take-off and launch location (CAR 901.74) 
  • Sheltered Operation – This allows the drone to be flown around a building or structure without the use of a visual observer, in accordance with certain conditions  
  • Medium Drones: You’ll be permitted to fly drones with an operating weight of up to 150kg  
  • With an Advanced Certificate already in hand, you meet the prerequisite to begin your Level 1 Complex ground school (more in a moment). If you’ve passed the Advanced Certificate but only hold your Basic because you haven’t yet done your Flight Review, you can pursue the Level 1 Complex
5G Drones

AND ROUTINE, LOW-RISK BVLOS?

 

This was an area the industry had really been pushing for in the new regulations. Specifically, to be able to carry out such flights without the need for a Special Flight Operations Certificate. Here, too, there’s good news:

  • After November 4 2025, you’ll be able to fly low-risk BVLOS if you hold a Level 1 Complex RPAS pilot certification (CAR 901.89). This means BVLOS in uncontrolled airspace and away from people
  • Permits the operation of a 250g – 150kg RPAS to conduct a BVLOS operation in uncontrolled airspace and one kilometre or more from a populated area 
  • In addition to holding a Level 1 Complex pilot certificate, you also need to be an RPAS Operator (RPOC) or an employee/agent of one and comply with the conditions of your certificate (CAR 901.88) 

    

INTERESTING NUGGETS: 

 

  • RPAS Operating Certificate uses the acronym RPOC rather than ROC (as was drafted previously). This is likely in response to anticipated confusion with the ROC-A or Radio Operator Certificate with Aeronautical qualification issued by ISED
  • The new regs contain detailed guidance for visual observers and their requirements in various scenarios
  • You can’t “daisy chain” Visual Observers for EVLOS over greater distances. The pilot/control station needs to be at the take-off and landing area and the RPA can’t go further than 2 NM from the pilot, control station AND VO. 
  • Despite previous suggestions, there is no medical requirement! Just fit-to-fly rules like previously

 

There are also some changes to SFOC requirements. Police operations at events won’t require an SFOC. Department of National Defence operations won’t require them, just adequate coordination. In addition, you’ll be able to drop lifesaving gear without an SFOC, providing you don’t create a hazard. 

Declarations, maintenance and servicing will take on a more prevalent role (not surprising, given the EVLOS, low-risk BVLOS, and the ease of restrictions on flying heavier drones). It’s also worth noting that the already-useful Drone Site Selection Tool (DSST) will get upgraded to include new situational data layers for lower-risk BVLOS. These layers will include population density, aerodromes, controlled airspace, and Detect and Avoid requirements.

KATE’S TAKE

 

Canada Gazette II is a massive document. I actually tried to do a word count and the computer simply froze in fear. But, in conjunction with all of the above, here are some final key takeaways:

  • Don’t freak out: There’s plenty of time to process and time to act. There are no major changes happening before November 4th, though you’ll probably want to get your ducks in a row before then if you anticipate your flying season extending beyond that date
  • For maybe the first time ever, regulations have outpaced technology. We still (desperately) need technical detect solutions that are reliable, capable and affordable
  • We’ve had a few folks reach out about ground school for Level 1 Complex and yes – we absolutely will be offering this. At FLYY, we have things well underway as we were anticipating this announcement.

Unlike previous ground schools, there are some instructor requirements that need to be in place before we can even make the declaration to TC that we’re offering TP15530 compliant training. We’re on top of it!

We plan to start offering live, TC-compliant courses prior to the end of April. Over a series of weeks, these courses will run every Wednesday at 0930 PDT for 2.5 hours. These sessions will be recorded and made available to all course participants to review or watch at their leisure. We’ll keep you posted as we get closer to launch.

You can take advantage of our presale here to make sure you’re first in line.

Get ready: New RPAS regulations are coming in Canada

Get ready: New RPAS regulations are coming in Canada

Mar 14, 2025 | Industry News, Kate Klassen, Regulatory, Scott Simmie, Transport Canada

By Scott Simmie

 

New Transport Canada RPAS regulations are coming. Precisely how soon is a question of some debate, particularly since the country just swapped Prime Ministers and is in the midst of a pretty unpleasant trade dispute with its largest trading partner.

Nonetheless, the work of government marches on. And in the near future we can expect Canada Gazette 2 to announce significant forthcoming changes to RPAS regulations which will be phased in likely by the fall of 2025.

That means this summer’s flying season, in some respects, will be business as usual. Beyond Visual Line of Sight flights will still require a Special Flight Operations Certificate through Transport Canada. But once the regulations come into force, low-risk BVLOS over sparsely populated areas will no longer require an SFOC, providing the pilot, organization and drone (up to 150 kg) all meet new requirements.

This will open up the door for the industry to carry out long-range BVLOS data acquisition and deliveries in low-risk scenarios without all the paperwork. But there will be some additional barriers to ensure these missions – and the pilots and organizations carrying them out – meet new TC requirements.

With the help of InDro’s Training and Regulatory Specialist Kate Klassen – who’s also a traditional aircraft instructor with multiple ratings – we’ll recap what’s coming, along with how to start preparing for the transition.

 A BALANCING ACT

 

Transport Canada, as regulator, has a delicate task: It needs to ensure airspace safety as much as possible while also allowing the industry to advance and grow economically. That’s what led to the first set of RPAS rules – Part IX of the Canadian Aviation Regulations (CARs) – announced in 2019. Those rules included the requirements for Basic or Advanced RPAS Certificates to operate drones weighing between 250 grams and 25 kilograms. It also laid out the regulations for where VLOS flight could (and couldn’t) take place and made it clear what type of missions would require an SFOC. Prior to Part IX of CARs, every commercial drone flight – including VLOS flight – required an SFOC. So that was a big step forward.

As the industry and its requirements continued to grow, TC started planning for the future. In mid-2023, this issue of Canada Gazette outlined proposed amendments that would ease the path to broader use-cases of drones while adding additional requirements on the safety and planning side of things. It’s a lengthy document, but its broad goals are boiled down to a single paragraph:

“This regulatory proposal would allow operations with a remotely piloted aircraft (RPA) up to 150 kg to be flown within visual line-of-sight and introduce rules for routine beyond visual line-of-sight operations with an RPA up to 150 kg over sparsely populated areas, at low altitudes, and in uncontrolled airspace. The proposal would remove the requirement for a Special Flight Operations Certificate (SFOC) for these operations…”

So the amendments will – in far greater detail – cover two new categories of operation: VLOS operation of drones weighing above 25kg and up to 150 kg (in both controlled and uncontrolled airspace) and BVLOS flights that meet low-risk criteria.

And the flip side of the coin? The paragraph continues: “The amendments include proposed requirements for a new pilot certification, new technical standards for the aircraft and supporting systems, new operational procedures, such as increased distances from airports, heliports, and people, as well as new requirements for individuals and organizations to operate BVLOS…”

It will be a significant step forward for operators, as part of TC’s measured approach to balancing safety and growth.

“This isn’t going to be the set of regulations that opens Canada up to delivering your pizza by drone,” explains Klassen. “But it will allow routine, low-risk BVLOS flights without the need for an SFOC. Detailed planning will still be required, but long-range data acquisition and deliveries in low-risk scenarios will become a lot more common.”

As noted, however, this isn’t a free pass.

“Operators wanting to carry out those low-risk BVLOS missions will need to demonstrate they have the knowledge and skills to do so. Pilots will need to obtain a new Level 1 Complex Pilot Certificate. And while it still covers the same eight knowledge areas as an Advanced RPAS Certificate, it’s to a whole new depth.” says Klassen.

Those with an existing or new Advanced Certificate will be able to carry out:

  • VLOS operations with a medium-sized drone (above 25 kg up to and including 150 kg);
  • Extended VLOS operations (EVLOS), using a visual observer; and
  • Sheltered operations, which would allow the drone to be flown around an obstruction (e.g. a building) without the use of a visual observer.

“You can temporarily put the drone out of your line of sight,” explains Klassen. “Say, fly behind a building or descend below the tree line if you’re comfortable with the safety and managing the risk of those scenarios. A cool example might be firefighters that need to duck the drone behind a plume of smoke so they don’t have to go the long way around.”

 

WHAT CONSTITUTES LOW-RISK BVLOS?

 

This is an important question – particularly when it comes to operating drones up to 150 kg. You wouldn’t want these flying in places that could put people, or traditional air traffic, at undue risk.

The proposed regulations (and we still have to wait to see the final language) indicate that TC will require operators to ensure their missions meet acceptable risk management criteria under SORA, an international guideline which stands for Specific Operations Risk Assessment. This combines calculating the ground risk (people, property, infrastructure) of a specific planned mission (where BVLOS obviously carries a higher risk than VLOS) as well as the air risk – the probability of encountering crewed aircraft in the airspace. The latter is calculated based on the density of traditional aircraft in the proposed operational airspace (higher density equals greater risk), plus any mitigating factors such as detect and avoid systems, robust operating procedures, etc..

The final language isn’t out yet, but the paragraph cited earlier contains the high points. Low-risk BVLOS flights that take place over sparsely populated areas in uncontrolled airspace and at altitudes not exceeding 400′ AGL will not require an SFOC.

There is, obviously, a big difference between VLOS and BVLOS, particularly when we’re talking about larger drones. BVLOS missions will involve more complex planning akin to traditional aviation. If it’s a long-range mission, what’s the anticipated weather on the route 100 km away in two hours? Pilots with their Level 1 Complex Certificate will need to take into account multiple risk factors that don’t generally apply to VLOS flight.

“The knowledge requirements will be a step above Advanced, for sure,” says Klassen. “You’ll be expected to to know about antennas and variables that can impact your C2 link reception, and how to apply that knowledge operationally. You’ll have to be able to look at a proposed route and understand how the environment and terrain features are going to impact your reception range – and even whether or not the proposed mission is even possible.

“We can also expect a lot more as well on crew communications and operating procedures for if things don’t go as planned.”

Below: These graphics, pulled together by Kate Klassen and InDro, cover key aspects of the anticipated new RPAS regulations

WAIT, THERE’S MORE

 

The new Level 1 Complex Certificate comes with a mandatory ground school requirement (you won’t be able to write the online exam without it), as well as a medical sign-off from your doctor to ensure you don’t have any untreated condition that could impact the safety of operations. That declaration from the doctor will be need to be presented at the more extensive in-person Flight Review the new certification will require. TC is also aligning the rules for company ownership to more closely align with existing regs for traditional aviation. These will be more favourable to Canadian citizens and companies with at least 75 per cent Canadian ownership.

Oh, the regs will also permit Extended Visual Line of Sight (EVLOS) flights with additional visual observers, and also allow for brief BVLOS flight if necessary within missions that might have been planned as VLOS only.

There will be much more, including the need for organizations to have an Accountable Executive responsible as the point person for overall ops – what Klassen jokingly refers to as the “one throat to choke” if things go wrong.

The fine print of the final regs, as noted, is yet to be released. But it will be a significant advance for the industry – coming with additional responsibilities and knowledge requirements for those involved. InDro will be ready, with updated courses on its FLYY online drone instruction portal run by Klassen. In fact, there’s already a free prep quiz for the new regs here.

Stay tuned.

 

 

New TC Advisory Circular contains guidance for night BVLOS flight – and much more

New TC Advisory Circular contains guidance for night BVLOS flight – and much more

Jun 7, 2024 | Education and Training, Industry News, Kate Klassen, Scott Simmie, Transport Canada

By Scott Simmie

 

A new Advisory Circular from Transport Canada is generating a lot of buzz in Canada’s RPAS world.

Although an Advisory Circular is not legislation, they offer guidance and a glimpse of what the regulator is planning for the future.

“Advisory circulars are one of the methods that Transport Canada can use to provide guidance on complying with regulations,” explains Kate Klassen, Training and Regulatory Specialist at InDro Robotics. Klassen is an instructor and pilot of traditional aircraft as well as drones. Her online courses have trained more than 10,000 RPAS pilots in Canada. She has also served as Co-Chair of the Canadian Drone Advisory Committee, or CanaDAC.

“It kind of acts like a preview, foreshadowing in a way the regulations we know are coming later this fall. This one in particular is exciting because of the depth of guidance that they’ve provided,” she says.

Here’s how Transport Canada describes the purpose of the Advisory Circular – entitled Remotely Piloted Aircraft Systems Operational Risk Assessment – in its introduction:

“This Advisory Circular (AC) is provided for information and guidance purposes. It describes an example of an acceptable means, but not the only means, of demonstrating compliance with regulations and standards. This AC on its own does not change, create, amend or permit deviations from regulatory requirements, nor does it establish minimum standards.

“This AC provides information and guidance to manufacturers and operators intending to develop or operate a Remotely Piloted Aircraft System (RPAS) for operations in accordance with the requirements of Part IX, Subpart 3 of the Canadian Aviation Regulations (CARs).”

The document itself is 131 pages, and a lot of it is dense and laden with acronyms. But for operators planning complex operations down the road – including the potential of flying BVLOS at night – the highly detailed guidance offered in the document is a gold mine. It goes into extraordinarily fine detail about carrying out Risk Assessment in a variety of scenarios.

Below: Screengrab from InDro research into urban wind tunnels being carried out for the National Research Council. This was a highly complex operation involving a heavier drone in a dense urban setting and required a Special Flight Operations Certificate. The new Advisory Circular helps spell out precisely what TC is looking for from operators to ensure safe operations in multiple scenarios

RISK ASSESSMENT AND SFOCs

 

Back in the early days of drones, pretty much every flight required special permission – an SFOC – from Transport Canada. As drone technology and reliability/robustness improved and the regulator collaborated with the industry, detailed regulations for RPAS were first issued in 2019.

That change meant what we could generally term as routine, low-risk flights with drones weighing up to 25 kilograms could be carried out without an SFOC, providing the operator met all criteria laid out in the Canadian Aviation Regulations, Part IX. That included requirements that the operator have a Basic or Advanced RPAS Certificate to operate small RPAS. TC also established its drone portal, where compliant drones weighing more than 250 grams are registered and assigned a number by the regulator. All of this was, in general, very good news for the RPAS industry.

But for those more complicated operations – generally meaning operations with greater risk – an SFOC was still required to satisfy Transport Canada that the operation could be carried out safely. Specifically, as the AC points out, SFOCs were (and are) still required in these circumstances:

“No person shall conduct any of the following operations using a remotely piloted aircraft system that includes a remotely piloted aircraft having a maximum take-off weight of 250 g (0.55 pounds) or more unless the person complies with the provisions of a special flight operations certificate — RPAS issued by the Minister under section 903.03:

(a)  the operation of a system that includes a remotely piloted aircraft having a maximum take-off weight of more than 25 kg (55 pounds);

(b)  the operation of a system beyond visual line-of sight, as referred to in subsection 901.11(2);

(c)  the operation of a system by a foreign operator or pilot who has been authorized to operate remotely piloted aircraft systems by the foreign state;

(d)  the operation of a remotely piloted aircraft at an altitude greater than those referred to in subsection 901.25(1), unless the operation at a greater altitude is authorized under subsection 901.71(2);

(e)  the operation of more than five remotely piloted aircraft at a time from a single control station, as referred to in subsection 901.40(2);

(f)  the operation of a system at a special aviation event or at an advertised event, as referred to in section 901.41;

(g)  the operation of a system when the aircraft is transporting any of the payloads referred to in subsection 901.43(1);

(h)  the operation of a remotely piloted aircraft within three nautical miles of an aerodrome operated under the authority of the Minister of National Defence, as referred to in subsection 901.47(3); and

(i)  any other operation of a system for which the Minister determines that a special flight operations certificate — RPAS is necessary to ensure aviation safety or the safety of any person.”

“In order to be issued an SFOC – RPAS, an operator must submit an application to the Minister as detailed in CAR 903.02. In particular, CAR 903.02 (p) indicates that in addition to the specific information required by 903.02 (a) through (o), the operator must submit “any other information requested by the Minister pertinent to the safe conduct of the operation”. For certain complex operations, as determined during the application process, an Operational Risk Assessment (ORA), acceptable to the Minister, is one of the items of ‘other information’ required in support of an application for an SFOC – RPAS.”

It’s that last paragraph that’s particularly relevant to this Advisory Circular.

 

COMPLEX PROCESS

 

The issue, as many operators discovered, was that applying for an SFOC wasn’t a slam-dunk. It’s not uncommon for TC to come back – sometimes more than once – asking for more details or requesting additional steps or precautions. This slowed the approval process, which was frustrating for operators. Some conveyed to regulators that there wasn’t enough clear guidance to ensure operators were meeting TC’s detailed expectations.

“So it made the SFOC application process for those more complex operations challenging as both parties were trying to sort out what the requirements needed to be to keep things safe,” explains Klassen.

The new Advisory Circular spells out, in detail, precisely what Transport Canada is looking for from operators. It contains multiple protocols, including the fine details of carrying out standardized risk assessments, that will be of benefit to all operators – even in cases where an SFOC is not required. Klassen believes the new document is the direct result of discussions between operators and TC. In addition to making complex operations safer, it provides all the fine print to assist operators in getting everything right the first time with SFOC applications.

“This Advisory Circular, I think, is a result of all of the back-and-forths between those RPAS operators who have been pursuing the boundary-pushing applications, and Transport Canada. TC has been able to accumulate all of that guidance in one location so that the process is streamlined.”

We’ll hit on a few highlights – including BVLOS at night – but the document is so thorough and dense that we’ll link so that operators can download and study it themselves. The Advisory Circular is so detailed that it’s not easy to synopsise, as you’ll gather from the following table of contents. (Don’t worry if some of the acronyms are unfamiliar; there’s an extensive glossary):

WHAT’S NEW

 

This is actually a revision to a previously published Advisory Circular. Because it contains so much information, TC thoughtfully provided a round-up of what’s new – and there’s quite a bit that is.

It contains the following changes to definitions:

  1. Airport / Heliport Environment was renamed Aerodrome Environment and a 3000 ft (915 m) AGL maximum altitude provision was added.
  2. (ii)  The Atypical Airspace infrastructure masking provision was clarified, and a low altitude night provision was added. (We’ve bolded this because it’s kind of a big deal, and we’ll get to it.)
  3. (iii)  Operating Weight definition was added to support changes to ground risk assessment.

In addition, ground risk assessment now relies on the weight of the drone rather than a kinetic energy calculation. Thresholds are now based on the most recently available population density numbers, rather than just a description of the area.

All ground risk scores now assume BVLOS operations; if you are carrying out a VLOS operation that is included as a mitigating factor.

There’s more, of course. But the most attention-grabbing line from above is the provision for low-altitude BVLOS at night. This will obviously require a risk assessment and SFOC, but it’s expected this will be included in legislation anticipated this fall (Canada Gazette 2). And that opens a lot of doors for operators.

“You could fly BVLOS along power lines, transmission lines because there’s not going to be an aircraft within 100 feet vertically of that. You could also carry out deliveries at night, pending airspace,” says Klassen.

It’s also worth noting that Transport Canada had previously indicated that routine, low-risk BVLOS flights will be permitted in the forthcoming regulatory amendments. An additional level of Transport Canada pilot certification will be required for such flights.

Below: With a satisfactory risk assessment and an SFOC, drones like this might be flying BVLOS missions at night when updated regulations are released sometime in the fall of 2024

 

HIGHLIGHTS

 

When Kate Klassen went through the AC, she was impressed with the extraordinary level of detail. Every step of risk assessment and mitigation is thoroughly described, with examples in the appendices.

Many operators will be familiar with risk assessment tools. But there will also be many, particularly those who currently carry out very basic, non-complex operations, who might know the acronyms but little beyond them. This is very much a “how-to” document.

An Operational Risk Assessment (ORA) is a very methodical process – once you know the method. And here, TC outlines the specific steps laid out by the JARUS (Joint Authorities for Rulemaking on Unmanned Systems) SORA (Specific Operations Risk Assessment) process. (There are some minor tweaks here, which are explained, to optimize this for the Canadian environment.)

The AC walks you through every step of the process, and includes graphics. The document takes a much deeper dive than this overview, with each phase of risk assessment explored in detail. This, however, gives you a glimpse:

TC Advisory Circular JARUS SORA

OPERATIONAL VOLUME

 

The document also defines something critical for any risk assessment – what it calls the “Operational Volume.” This involves calculating boundaries beyond the planned flight operations for safety/mitigation/contingency purposes.

Here’s how the Circular defines it:

TC Advisory Circular Operational Volume

“ATYPICAL AIRSPACE”

 

One of the things that caught Klassen’s keen eye was the definition of Atypical Airspace. Here’s the wording from the Advisory Circular:

  1. (i)  Restricted Airspace, with authorization from the person specified in the Designated Airspace Handbook TP1820 or in a NOTAM.
  2. (ii)  Northern Domestic Airspace as defined in the Designated Airspace Handbook, outside an Aerodrome Environment, at a maximum altitude of 400 ft (122 m) AGL.
  3. (iii)  Within 100 feet (30 m) above and within 200 feet (61 m) horizontally from any building or structure which stands out vertically beyond the adjacent surface of surrounding terrain with sufficient size and shape to be noticeable to the pilot of a traditional aircraft in flight.
  4. (iv)  Within the hours of legal night, in uncontrolled airspace outside of an Aerodrome Environment, at a maximum altitude of 400 ft (122 m) AGL.

Why is this extension to the definition of Atypical Airspace (AA) exciting? When an operation takes place in AA, the Air Risk Class is automatically assigned as “a” (ARC-a). This lowers the relative SAIL, depending on your Ground Risk Class, and therefore the requirements to meet the operational safety objectives are simpler. It will give you a much easier time applying for and obtaining your SFOC due in major part to the Detect and Avoid options available to you to use.

Below: With adequate lighting (and more safety precautions), operating at night provides some interesting BVLOS opportunities!

 

INDRO’S TAKE

 

Transport Canada’s new Advisory Circular is an important, detailed, and well thought-out document. Yet again, TC is attempting to make things easier for professional operators while striking that critical balance of safety – both in the air and on the ground.

“The past decade has seen both tremendous advances in the reliability and safety of drones, and – after some initial resistance in the early days – tremendous willingness on the part of Transport Canada to safely open up new opportunities for the industry at large,” says InDro Robotics CEO Philip Reece.

“The level of detail in the Advisory’s extensive sections on Risk Assessment will be of great benefit to operators – and to the safe expansion of the industry into other use-cases, including BVLOS flights at night. We commend those at Transport Canada for both the vision and thought put into this document, and look forward to the new regulatory changes.”

FLYY releases “how to” guide for building, expanding a drone program

FLYY releases “how to” guide for building, expanding a drone program

Apr 29, 2024 | Education and Training, Kate Klassen, Scott Simmie, Transport Canada

By Scott Simmie

 

Thinking of starting a drone program? Perhaps you have one already, and are thinking of expanding. Or maybe your existing program grew organically on an ad-hoc basis and you’d like to ensure you’re following Best Practices.

There’s a solution for that.

Kate Klassen, InDro’s Training and Regulatory Specialist (who’s also a flight instructor for crewed aircraft),  has written a comprehensive manual specifically for this purpose.

Klassen is widely respected in Canadian RPAS and traditional aviation circles. In addition to her extensive experience as a pilot (multi-engine rating, IFR, night), she was an early adopter in the drone world. Her regulatory expertise is top-notch, and her online RPAS instruction courses have trained more than 10,000 pilots in Canada (you can find her current courses here). She’s been on the board of the Aerial Evolution Association of Canada for years, and was co-chair of Transport Canada’s CanaDAC Drone Advisory Committee. So she knows her stuff.

Now, she’s pulled together that knowledge (in addition to what she’s learned working with InDro Robotics and consulting with other companies with RPAS programs) into a single, comprehensive document that covers everything you need to know to build out a safe, compliant, cost-effective drone program.

“The goal with the book was to put in one spot all of the information that you should know,” she says.

She certainly achieved that.

Below: Kate Klassen, in one of her many elements.

SOLID KNOWLEDGE BASE

 

The e-book is entitled Remotely Piloted Aircraft Program Development Guide for VLOS and BVLOS Operations. And it covers pretty much every aspect of running a drone program – including maintenance, staffing, recency, risk assessment – and much more (we’ll give you a peek at the table of contents shortly).

There’s also, of course, a meaty section on the regulations – including the anticipated Transport Canada changes on the horizon that will permit routine, low-risk Beyond Visual Line of Sight flights (which will require obtaining an additional TC RPAS Certificate). And while the book covers high-level operations suitable for companies with mature drone programs, it also covers the basic meat and potatoes.

“This book could be used by individuals looking to use their drone in a professional capacity or as a really serious hobby – but it’s geared more for someone who is either starting, expanding or improving a drone program within their organisation,” says Klassen.

 

DECISIONS, DECISIONS, DECISIONS

 

A well thought-out drone program involves a lot of decisions. How do you choose your crew, including flight lead? When is it time to replace an aircraft? What’s a good maintenance schedule – and how do you track that? What’s the best way to manage data? And what about insurance?

You’ll find all that and more. Klassen has packed a lot (including links to references and resources) into the 55 pages of this manual. And she’s taken special care to pore through the finer details of dense Transport Canada regulatory language and write the key takeaways in clear, concise terms.

“There was a lot of digging through Transport Canada documents to gain insights into where the drone industry is going from a regulatory perspective – and put that into plain English,” she says.

LOGICAL, ORGANIZED

 

Whether you’re a seasoned pro or someone just starting a drone program, Klassen has constructed the manual in a highly organised fashion. The progression of sections builds logically from the basics, through to complex areas such as Specific Operational Risk Assessment (SORA).

Here are the sections:

  1. Regulation Roadmap
  2. Certification
  3. Operational Considerations
  4. Budgeting
  5. Program Structure and Operation
  6. Training
  7. Equipment
  8. SORA Process

And within each of those sections? Let’s just say Klassen has it all covered. Take a look:

EXCERPT

 

It’s one thing to tell you this manual is clear and concise. It’s another to let you see for yourself. So we’re going to paste from the very top of Section One – Regulation Roadmap – to give you a better idea:

The Canadian Remotely Piloted Aircraft System (RPAS) industry took a major leap forward in June of 2019 with the publication of drone-specific regulation in the Canadian Aviation Regulations (CARs). These regulations enable route visual line of sight (VLOS) operations for small RPAS (250g – 25kg), with additional guidance for aircraft above that weight range, through a Special Flight Operation Certificate (SFOC) process, and below, with reduced prescriptive microdrone regulation.

With the release of a Canada Gazette draft of lower risk BVLOS regulation in the summer of 2023, we have an idea of the direction Transport Canada is heading and had an opportunity to raise concerns and encourage positive direction with the drafted version.

While formal regulation, once in place, will provide a clearer path to certification for BVLOS, there will still be many of the similar requirements to what’s currently in place, through the SFOC process, including training, mission planning, procedure development and technology.

  • NOTE: While BVLOS with a microdrone is not explicitly prohibited by the regulations, the onus would be on the operator to prove it was done without being reckless, negligent, risking or being likely to risk the safety of a person or aviation safety. (CAR 900.06) Throughout this document, the aircraft and operations we’ll be referring to are those with small RPAS, that is those between 250g and 25kgs, unless otherwise specified.
  • As it stands as of the time of publication, flying an RPA heavier than 25kgs or BVLOS is not permitted in Canada except if specifically authorized in a Special Flight Operation Certificate. (CAR 901.11) This document will address considerations for a BVLOS program in anticipation of BVLOS-specific regulation being introduced in 2025 and the structure, operational considerations, components of an SFOC and training.

This is a rapidly changing space. As the industry continues to develop new technology and applications, and new regulation is announced to accompany these advancements we’re going to see a lot of refinement to the processes described within this document. It’s what’s so exciting about working in this area! The information here should help you in that pursuit.

As you can see, it’s really clearly written. It’s also filled with helpful graphics like these:

INDRO’S TAKE

 

Kate Klassen is widely acknowledged as both a regulatory expert and a phenomenal communicator/instructor. She combines those skills well in the production of this manual, which we believe is a “must-have” for anyone serious about their drone program.

“Kate has tremendous expertise in this field – including personally overseeing some 150 RPAS flight reviews,” says InDro Robotics CEO Philip Reece. “This manual ticks all the right boxes, and includes material that will benefit even the most mature drone program. We’re pleased to see this published, and believe it will truly help those running serious programs make the most effective and efficient decisions.”

And the cost? You can download the manual here for $49.

That’s less than a dollar per page. And, in our opinion, a bargain.

TCXpo brings Smart Mobility exhibit to Ottawa’s Area X.O

TCXpo brings Smart Mobility exhibit to Ottawa’s Area X.O

By Scott Simmie

 

Canada’s largest Smart Mobility exhibit and demonstration took place in Ottawa September 27.

It was the second time the annual event has taken place. It brought hundreds of attendees – and more than 75 companies – to Area X.O, an innovation hub where leading Smart Mobility companies carry out research and development. The facility features a private 5G network and private roads, allowing companies to test and harden robots, drones, autonomous passenger-carrying vehicles, and more.

Sponsored by Transport Canada (that’s the “TC” in “TCXpo”), along with Invest Ottawa and Innovation, Science and Economic Development Canada (ISED), the event showcases innovations in the smart mobility space. Think the latest and greatest robots, drones, self-driving vehicles – along with a plethora of hardware and software associated with the sector.

“Today, we will celebrate Canadian innovation,” said Sonya Shorey, Vice President Strategy, Marketing and Communications of Invest Ottawa as she opened the show.

“Companies driving the smart mobility revolution. Innovators developing and commercializing multidisciplinary solutions to grand challenges and market opportunities. These innovations span every sector – from intelligent transportation to defence, public safety, security, aerospace, environment, smart agriculture, and telecommunications. And they are being developed by Canadian leaders.”

As Michael Tremblay, President and CEO of Invest Ottawa, Area X.O and Bayview Yards, put it: “We’ve got incredible capability right across the country.”

DARTT

 

One of the highlights of the show was the new Drone and Advanced Robotics Training and Testing facility, also known as DARTT. Built to the demanding criteria of the US-based National Institute of Standards and Training (NIST), DARTT is designed for evidence-based evaluation of drones over a variety of surfaces (including sand, gravel and water) and obstacles (including a variable incline ramp). There’s also a netted enclosure for flying experimental drones or assessing new payloads and failsafe features in a safe environment.

InDro’s Luke Corbeth hosted tours of DARTT, allowing spectators to take control of various robots and operate them over obstacles. Here, he explains the basics of the facility:

STREET SMART ROBOT

 

InDro also publicly unveiled one of its newest innovations: The Street Smart Robot, or SSR.

Built with the support of the Ontario Vehicle Innovation Network (OVIN), led by the Ontario Centre of Innovation, the SSR will be monitoring bicycle paths in Ottawa this winter to detect snow, ice, potholes and debris that might impact the safety of cyclists. When those anomalies are detected, they’ll be flagged to road and maintenance crews at the City of Ottawa so they can be remediated.

Initially, the SSR will be remotely teleoperated by a human being who will have real-time situational awareness of all surroundings. The eventual goal is for the SSR to operate autonomously, with AI flagging problems so they can be sent up the chain.

Here’s a peek at the Street Smart Robot:

PLENTY TO SEE

 

With more than 75 companies (and an estimated 1200 attendees) at TCXpo, there was no shortage of things to see and demonstrations to watch. Some of the highlights of the day included seeing:

  • The Skygauge drone, a unique design purpose-built for non-destructive testing, carrying out a demo flight. Its NDT probe was delicately placed against a pole while in flight, mimicking the routine carried for testing of metal tanks, coatings, etc.
  • The Wingtra drone, carrying out a flawless demo mission. The fixed-wing, two-motor VTOL is capable of transitioning to fixed-wing forward flight from hover, giving it great range and efficiency
  • A driverless tractor carrying out a circuit on a field, with commands sent remotely from a phone. Such devices will be common in the Smart Farms of the near future

Plenty of things caught our eye, including a remotely operated hang-glider (low cost, long range, high payload). There was a new Nokia dock system, allowing for automated flights in remote locations. The system recharges the drone, checks all systems, while maintaining a safe harbour from inclement weather – perfect for regular inspections in remote locations. There was even a US startup that has developed a system that will automatically lower car windows if you happen to plunge your vehicle into water.

We’ve gathered a few pix of the above – and more – which you’ll see in the gallery below:

INDRO’S TAKE

 

The first TCXpo – despite the rain – was great. This one was bigger and better – and the weather was perfect. The demonstrations and exhibits collectively made it clear: Smart Mobility is coming.

“Part of the growth between the inaugural TCXpo and this display was due to word of mouth,” says InDro Robotics CEO Philip Reece. “But part of the equation is that the industry itself is growing at a rapid pace. The world of Smart Mobility may not have yet arrived, but you can definitely see it’s on its way.”

Finally, a tip of the hat to Transport Canada, ISED, Invest Ottawa and Area X.O. Those kudos aren’t just for putting on a great show – but also for having to vision to realize that this sector will create jobs, improve safety and contribute to greater efficiency in the not-so-distant future.
