Keep in touch with the latest news in the drones community
According to the ICAO’s RPAS manual, a full Detect And Avoid (DAA) system must prevent collisions with: conflicting traffic, terrain and obstacles, hazardous meteorological conditions, ground operations and other airborne hazards (such as wake turbulence, birds and volcanic ash). However, most of the existing efforts focus on DAA for conflicting traffic as it represent the highest risk, letting aside the rest of the hazards. Especially in the case of ACAS Xu which design and evaluations focus on conflicting traffic avoidance.
Recently, Trustwave applied for a patent describing how to integrate existing terrain and weather avoidance systems with ACAS Xu. The goal being to inhibit collision avoidance maneuvers which could direct the RPAS into terrain or hazardous weather, and to account for these in the computation of Remain Well Clear (RWC) maneuvers.
The efficiency of such a system remains to be demonstrated, yet it is one step closer to a complete DAA system.
The Airports Council International (ACI) recently published a position paper on Drone Technology giving an insight on their vision of the future. In this documents they acknowledge the important role that drones can play for the development of airport activities, the impact that drones traffic will have on airports, as well as the risks in termes of security and disruption of airport services.
The ACI asks for a common european effort, with a “no airport left behind” approach, and calls for cooperation with airlines, ANSPs and authorities, on topics including: the definition of restricted zones (geofencing), the detection and neutralisation of drones, and the definition of roles and responsibilities of the various actors. In this regard it strongly supports the U-Space initiative led by the SESAR-JU.
In terms of actions, the ACI World set up a “Drones Working Group” aimed at writing a Handbook and global guidelines for airports. At the same time, ACI Europe asks the EASA to write and publish a “European Safety Rulebook” to disseminate good practice and safety culture to the public. The ACI also acknowledge that a medium to long term integration will require to update relevant ICAO documents.
The envisioned roadmap for drones integration is to integrate the less risky operations as fast as possible, then define standard scenarios to enable operations in the EASA framework and finally gather from the aviation industry best practices and operational concepts.
In all the previous aspects, the ACI insists on the fact that any development must be “future proofed”, it is to say that it should be able to evolve as the technologies evolve.
MM Sharples and Jestin held a conference in ENAC Toulouse premises to give an overview on the Chair activities and ongoing projects. This event gathered students, ENAC staff, researchers, professionnals, and we’ve had the opportunity to host members from SESAR-JU and the Japan UAS Industrial Developement Association.

The RTCA Drone Advisory Committee (DAC) is a committee aimed at supporting the FAA on their regulatory effort to enable drone integration in the national airspace. The 8th of November, the DAC is meeting to consolidate their finding and reach consensus on the recommendations to provide to the FAA. This is likely to trigger from the FAA an update of existing regulation thus impacting the whole drone industry.
