I had my 1st test flight and drone flew fine, a few quirks but I was in very restricted airspace - a driveway surrounded by trees. This was just a low altitude test of the camera and the drone hovered and moved correctly.

The remote would beep fairly often but I suspect this was largely obstacle detection as getting out towards the street tended to get rid of the beeps. I have no time to get to a nice open space for a few days to confirm this true. However would this be expected behavior, the space is perhaps 25 feet wide with large vegetation on both sides and above - there is some clear sky above.

I could not find any specific information on obstacle sensor ranges, and when beeping starts to confirm this, and I am not anywhere near ready for sport mode yet.

I did calibrate everything prior to the 1st flight, sticks look good in the calibration utility, move well, and return to center. Apologies if I missed this info in my search attempt.

It sounds like the area you flew in is not a suitable spot for learning to fly.
Collision with obstacles is the major cause of problems and obstacle detection is not foolproof.
A large, clear area well away from trees, buildings and other obstacles is best for learning to fly.
When there's nothing to hit, it's hard to get into trouble.

Here's the relevant section from the Specs for the mavic Air:
Forward
Precision Measurement Range: 0.5 - 12 m
Detectable Range: 0.5 - 24 m
Effective Sensing Speed: ≤ 8 m/s
Field of View (FOV): Horizontal 50°, Vertical ±19°

Backward
Precision Measurement Range: 0.5 - 10 m
Detectable Range: 0.5 - 20 m
Effective Sensing Speed: ≤ 8 m/s
Field of View (FOV): Horizontal 50°, Vertical ±19°

Downward Altitude Range: 0.1 - 8 m
Operating Range: 0.5 - 30 m

Operating Environment
Forward:
Surface with clear pattern and adequate lighting (lux > 15)

Backward:
Surface with clear pattern and adequate lighting (lux > 15)

Downward:
Detects clearly patterned surfaces with adequate lighting (lux>15) and diffuse reflectivity (>20%)
 
@Meta4 thank you for your reply and the data, and not yes suitable for learning. All I want to do was test auto take off, compass calibration, stability and stick function/calibration. I figured locked in beginner mode those would be ok, it occurred to me after the fact obstacle sensors might not be happy.

But all the basics work, so now I just need to drive to a nice big open area, away from water. There are a few but they are a bit of drive so best for the weekend.
