“Sense and Avoid” (SAA) capability
This is the one aspect that I have yet to see addressed. Aircraft operating under VFR are responsible for their own separation. This is mostly done by "see and avoid". The use of TCAS or other transponder detection solutions can be used, but keep in mind that not aircraft have transponders (gliders, older GA aircraft without an electrical system).
As a general aviation pilot, I have a huge incentive to see and avoid other aircraft. UAV pilots don't have the same incentive level. It scares me that this one simple aspect has yet to addressed.
- vowelless 13y agoPerception is the hardest part [1] for autonomous aircrafts, and from my experience, perception research for aircrafts is still in its infancy, albeit a hot research topic. In some ways, it is easier than self driving cars due to the added DOFs, but in other ways can be quite complicated due to weather conditions.

- krasin 13y agoPart of that issue is the lack of high-performance and lightweight board for real-time machine vision (you won't have an NVIDIA GPU + x86 board as a part of your multicopter). All hopes that Parallela board (http://parallella.org http://parallella.org) will make it feasible.

Its amazing to think the core processors on an original (1990s design) F-22 Raptor could be duplicated on an embedded PC today. Current Multi-core PowerPC processors and FPGAs would be capable enough. I backed Parallela but haven't received the board yet.
- neurotech1 13y agoA Navy jet like a F/A-18F Super Hornet can fly a "coupled approach" in gusty winds, onto a pitching deck and still put the tailhook onto the #3 arresting cable accurately. Navy F/A-18s can fly with terrain following radar to avoid hazards. Auto-pilot with "Terrain Aviodance" mode is related to the Terrain Awareness and Warning System (TAWS) [1] Auto-Throttle on a commercial airliner like a 777 can correct for deviations caused by gusts and other weather conditions. Careful parsing of METAR[2] information can guide jets away from weather fairly easily. Airline pilots manually set the autopilot to weather hazards but this could be done automatically in the near future.
