At the Light Aircraft Design Conference last year the man from the CAA Stated that the consultant had used 1000 simulated aircraft without issue. I have two issues with this. Simulated is unlikly to represent real life transmissions and 1000 is way too low.
Last year I tried a new design of ADSB antenna, nothing special, just a properly designed dipole mounted on the front screen. At 3000' over middle England, I was able to track a Harvard doing circuits in Holand! I was unable to count how many ADSB contacts I had on screen as the screen refresh stopped me scrolling to the bottom. SkyDemon also gave up trying to display them all, failing to display close contacts that I know we're outputting ADSB. Hence I pushed Lee for range filters. Before Lee asks I don't think I have the log file.😒
Scroll forward to a time when all aircraft, para motors, drones, balloons etc have ADSB. I think there may be issues wit transmissions being stepped on, and becoming corrupted.
