The DAA vs. Obstacle Avoidance Distinction Quietly Became One of the Most Important Compliance Points in Canadian Drone Operations

When Transport Canada's Level 1 Complex Operations certification became active last November, it opened a pathway for qualified operators to conduct BVLOS flights without the case by case expense of an SFOC application. For teams running infrastructure inspection, pipeline ROW patrols, or large site mapping, this was significant. The certification removed a structural friction point that had been limiting scale for years.

But buried in the details of the Level 1 Complex requirements is a distinction that most commercial operators initially missed, and that the April 2026 Drone Zone newsletter went out of its way to clarify: obstacle avoidance systems are not Detect and Avoid (DAA) systems for the purpose of BVLOS operations.

This matters in a very specific way.

What DAA Actually Requires

Detect and Avoid, as defined under Standard 922.10, is about detecting and avoiding other aircraft, not obstacles. When you are flying beyond visual line of sight, you lose the ability to see and avoid manned aircraft using only your own eyes. DAA is the functional replacement for that visual separation capability.

What most drones call obstacle avoidance is a short range sensor array: ultrasonic, stereo camera, or LiDAR that detects static obstacles near the aircraft, trees, buildings, towers or the ground. It is useful for flying close to structures and for low altitude safety in controlled spaces. It is explicitly not sufficient for BVLOS operations because it cannot see an approaching helicopter at altitude two kilometers away.

For BVLOS flights under Level 1 Complex certification, the pilot must maintain DAA capability either through visual observers (VOs) positioned along the flight path who can communicate aircraft traffic to the pilot, or through an approved DAA system that can detect other aircraft with enough lead time for the drone to maneuver safely.

The two are not interchangeable in all contexts. Visual observers work for low altitude, low speed operations in areas with predictable traffic patterns. A DAA system is preferred for operations near airports, heliports, or any environment where unexpected aircraft traffic is plausible.

The Practical Implication for Equipment Decisions

For operators who have been building out fleet capabilities around drones with advanced obstacle avoidance systems like those found on some enterprise platforms, or third-party perception arrays, there is a real risk of having misread the equipment's qualification for BVLOS work.

Having a drone with excellent obstacle avoidance does not mean you can fly BVLOS without VOs or an approved DAA system. It means you have a system that helps with low altitude static obstacle management. Those are genuinely different safety functions.

Manufacturers who want their platforms to qualify for BVLOS under Level 1 Complex need to go through the Pre-Validated Declaration (PVD) process and demonstrate compliance with Standard 922.10 specifically. That is a more involved certification path than simply equipping a drone with proximity sensors.

The practical result is a split in the market: drones that are certified for Level 1 Complex BVLOS operations, and drones that are not. Operators who bought equipment based on obstacle avoidance performance without checking the DAA compliance status may find themselves in an operational gap flying legally but not for the work they thought they would be qualified for.

What Operators Should Do Now

If you are running Level 1 Complex certified operations or planning to, the first practical step is to audit your current equipment against the actual DAA requirements, not just the obstacle avoidance marketing.

Check whether your drone manufacturer has filed a Pre-Validated Declaration that includes Standard 922.10. If they have, the platform is DAA qualified for BVLOS. If they have not, you are operating under the Visual Observer requirement, which is workable but places more operational constraints on your mission planning.

For operators procuring new equipment for BVLOS work, this should be a procurement requirement, not an afterthought. Ask the manufacturer directly whether their platform has been through the PVD process for Level 1 Complex operations. If the answer is unclear or the documentation is not available, treat it as a compliance risk until proven otherwise.

The Broader Takeaway

This distinction between a system that keeps a drone from hitting a tree and a system that keeps a drone from hitting an aircraft is one of the technical details that separates regulatory compliance from operational reality. Level 1 Complex certification gave operators a genuine pathway to scale BVLOS work in Canada. Actually flying under that certification requires understanding what the requirements actually mean for the equipment you are flying.

Operators who encounter regulatory issues are not typically trying to cut corners. More often, they have purchased capable equipment and obtained the necessary certifications, assuming the two would automatically align.

In reality, they do not. Both the equipment and the certification must independently meet the standards, which are often more specific than marketing materials imply.
