UAV Collision report here
One of the most poorly researched and implemented set of tests I've seen in years. Badly thought out and biased.
An excellent appraisal
here...
The authors are fully aware that the data is unreliable, uncalibrated and invalid by their own definition of the modelling process, yet they fail to admit this.
At present the UK government is poised to give Amazon permission to operate delivery drones at altitudes up to 400ft throughout the UK. Amazon drones will be flying autonomously and will have sense and avoid systems. However it is impossible for them, or any drone for that matter, to detect an aircraft travelling at 60 knots or 70mph and move out of its path in time to avoid a collision.
This study therefore demonstrates there is a clear and present danger to the GA community should Amazon be allowed to implement its delivery drone concept. For some reason though this rather obvious conclusion has missed BALPA, the DfT, the MAA, the CAA, and Lord Callanan. Instead once more hobbyist drone pilots are targeted, their potential threat overstated and the real threat to aviation missed entirely.
