Researchers at Embry-Riddle Aeronautical University in Florida and Unmanned Robotic Systems Analysis (URSA) have developed a new way to accurately count and objectively analyse close encounters between drones and aeroplanes – without depending solely on pilot sightings.

The team analysed over 1.8 million piloted aircraft operations and nearly 460,000 flights by small, uncrewed aerial systems (sUAS) around Dallas–Fort Worth airport. 

During a three-year period, the team identified 24 near-midair collisions (NMACs) between sUAS and aircraft, including two in 2018, one in 2019, 14 in 2020 and seven in 2021. The majority of close calls occurred within 1.5 miles of a runway approach or departure zone.

To avoid collisions, the researchers recommended extending the runway exclusion zone for drones at the end of high-risk runways from around one mile to 3.5 miles. 

“That modification would provide enhanced protection for piloted aircraft operating at less than...

  • Very interesting article of research on danger of collision between drones and air planes, especially during landing and take off.     Recommendations given by researchers to avoid collision between drones and planes; extend air exclusion zone on both ends of runway from 1 mile to 3.5 miles because in this areas of approach and departure the planes come less than 500' height, and drones typically don't fly higher than 400'.   NOW it seems there will be an imaginary rectangular duct with base and top of 3.5miles+ Runway Width+3.5miles and both sides of 500' and length of the duct will be Runway length + 3.5miles on each end..    AND in this imaginary duct the drones should not enter.    How to ensure drones wont fly above 400', design limitation or the operator's discretion? How to make sure drones don't enter this exclusion duct , and if they do who will take action and how and what?   It is quite serious as population estimate of drones / sUAS (small, Unmanned Aerial Systems), is 1.46m and in 2025 FAA predicts 2.5m.
