Another Police Helicopter

FAA actually doesnt allow that. Instead UAV are required to broadcast their serial number and position from takeoff to landing using Remote ID, https://www.ecfr.gov/current/title-14/chapter-I/subchapter-F/part-89

Interesting.  Almost like ADS-B Out. I presume it's on an different frequency but couldn't readily see the requirements and probably wouldn't understand the government gobbledy-gook anyway.

As I understand it, recreational drones are limited to 400 ft AGL.  Most general aviation isn't that low.

Yes, but it happens.

Helicopters and crop dusters are generally obvious to someone keeping their UAV in sight.  Someone buzzing their house will probably put their transponder in standby, assuming they have one to begin with.  From your link above, it looks like the recreational UAV will report itself as being over 400 ft AGL using the Remote ID and drones operating under Part 91 will have ADS-B Out.


This looks interesting:

(medical) Helicopters and crop dusters arent usually trying to move undetected.

How fast can you land a drone at 400 AGL? 

Descend too fast and you fly into your own prop wash and you are in freefall.

Descend too slow and someone flies into you faster than you had the ability to respond.

I'm looking at getting a new drone that gets around this by not requiring remote id.  It's based on weight I believe.  The one I'm looking at is far too small.
