> that sense-and-avoid won't solve the problem entirely, since there's a fair number of aircraft that are not transponder equipped. To be honest, I kinda hate the fact that DJI won't bring Airsense to the smaller drones. I love my Air 2S and I've seen it in action many times, helicopters often give you a 30-40 second window to get out of the way before you even see them.

I generally haven’t found it useful. Too many false positives, and too many aircraft not using transponders - especially helicopters in Class G airspace. Personally I’m hoping for some basic radar functionality, but that is going to be tough in smaller drones!

  I’m struggling to understand how Airsense would create a false positive (detect a plane that wasn’t there). It’s just listening for ADS-B out signals, which contain GPS position information. Perhaps DJI could be being overly conservative in their algorithm, but the airplane that’s in the ADS-B transmission really is where it says it is.

    I do a decent amount of flying in non-LAANC controlled and military controlled airspace (some near active airports). At least on the M300 RTK, their algorithms are total junk, and I get endless warnings (and serious ‘oh my god, reduce altitude now!’ type alerts for aircraft like jetliners coming in for approach - when I’m 90 degrees off their flight path, and 3-4 miles away. I also get critical warnings for aircraft flying overhead, which hey could in theory be a problem - if they weren’t climbing at 1k ft/min+, and at least 10k feet in altitude over me, when I’m at 200 ft AGL puttering around and the nearby trees are 100 ft tall. It’s literally worse than useless, as it makes gives alarm fatigue. I’ve also had 3 sudden aircraft just showed up and almost ran me over events in Class G airspace, including one with a very expensive helicopter running nap of the earth - none of them were running transponders. But at least the helicopter pilot had some bitching sunglasses on.
