AirSense not working with Air 3S/RC2

[JonJonPiperson]

Just got an Air 3S with RC2 and have taken it out a few times. Not sure why, but AirSense doesn't seem to be working at all.

I'm coming from an Air 2 with the non-smart controller hooked up to a phone. It's very clear I _should_ be seeing planes, because I'd see traffic all the time at my usual spots right on the edge of Class C airspace with the old controller and drone. I check FlightAware and definitely see traffic that I should be seeing on the RC2, and no. Yesterday I saw a plane within a thousand feet and up about a thousand, got no notification, but the plane was transmitting via ADS-B, visible on FlightAware.

I've checked the firmware and I'm up to date. Went to Safety -> Advanced Safety Settings -> And AirSense is turned on. I turned it off and on again just to make sure I wasn't missing some hidden acknowledgment. On the map view, I click the plane icon and have it set to "low, medium, high collision risk"

Does this require data/Wi-Fi to be on? I have the controller using my phone's hotspot via Wi-Fi. I read something about the connection not being on when the motors are running? Does this matter?

Is this a known issue? Anything else I may have missed here?

AirSense is designed to alert you to nearby manned aircraft equipped with ADS-B "out," but not all aircraft broadcast this signal.
The system also requires a direct line of sight with the aircraft's transponder.
Most Military aircraft do not use ads-b "out" and while they are equipped with it, It is usually disabled for security reasons.

I actually had the same question for a while now, but I haven't asked yet. I came from an Air 2S, and I live about 1/4 mile from Class C, and planes fly a lot in my area. The Air 2S would alert me all the time, even with single engine planes (I also get commercial airliners as well). But my Air 3S with RC2 never alerts me, even with it turned on.

Many private airplanes also do not have ADS-B.

• Aircraft age and type: Older aircraft, especially those with simple systems, are less likely to be equipped with ADS-B.
• Flight path: Aircraft flying at lower altitudes or in less-controlled airspace are not required to have ADS-B.

But in my case I am literally in the flight path of the main airport in my area, I am about 3/4 mile outside the 5-mile radius. Commercial planes (Southwest, Delta, etc...) fly over my house on a regular basis, and I NEVER get alerted. But I got alerted all the time with my 2S.

Understood, but I was also using FlightAware on my phone. I'd visually spot a plane, look it up on FlightAware, look at the Track Log for the plane, and it would be all ADS-B data. I'm just outside of KOAK and these are all airliners headed on up to FL600, so they definitely have ADS-B out.

I'm not sure if this is the drone, the controller, or some buried setting that I don't know about.

It sounds like you have the correct settings. That aircraft 1000' away at about 1000' AGL should have shown up on the controller since you confirmed it was broadcasting ADS-B via FlightAware.

If you still have the Air 2S, is it showing aircraft nearby?

(FL600 is 60,000 feet. The Concorde was probably the only commercial airliner to reach that altitude.)

I do still fly it, and it's giving me alerts just fine.

A possible wild card here is I'm using it with the RC-231 controller plugged into an iPhone, where I'm using the RC2 with the Air 3S. I don't think that would make a difference since the receiver is in the drone itself, but I wanted to make sure there wasn't something weird going on like I have to pair the RC2 with a phone even though it's a freestanding controller, or there's some magical setting I didn't see.

Either I wasn't fully caffeinated when I typed this, or Southwest has taken early delivery on those Boom jets.

Are you sure your settings are correct?
