Mavic Air 2 - Posessed

[jwnz]

Hi everyone,

Last week I was flying my Mavic Air 2 when out of absolutely nowhere it flew at full speed sideways into a wall from 50 ft. up, does anyone know what could have caused this?

I was flying directly next to an airport, where I had to request FAA clearance through kittyhawk, and submit a custom unlock via the DJI website - The only thing I can reasonably think happened is that an aircraft flying above possibly caused some type of interference?

• I calibrated my entire system 10 minutes before going into flight
• I was flying inside a 200ft. high, empty warehouse

I sent my drone into DJI yesterday so I should have more info from them next week (fingers crossed).

Welcome to the forum.
My guess is that you lost GPS signal because you were in a warehouse and it went into atti mode but if you post the log files the experts here will be able to likely tell exactly what happened. Mavic Flight Log Retrieval and Analysis Guide

It will be interesting to know the malfunction... likely DJI will not provide any details beyond whether or not it seems to be a defect or a pilot error. Best of luck.

and... Welcome to the forum from the deserts of Arizona! Enjoy.

What warehouse?

What warehouse?

He mentioned in his OP that he was flying inside an empty warehouse.

What warehouse?

Best Buy's new logistics HQ in Chino (It's being built) and I'm working on a timelapse for them. Unfortunately like an idiot I didn't pull my DAT file before sending the drone off to DJI

You get those files from the tablet/phone you used to fly.

Was this event inside a warehouse or other building?

I was filming inside the warehouse (empty) with plenty of room (over 100ft above and on each side of the drone)

I missed that... duh. All will be speculation without logs... @Tufargon is likely correct.

Like others suggested, pull some of your flight records off your device and post it in this thread. Open up the DJI FLY app and go into profile, more, and enable all records. Click the last flight, guessing that's the one you crashed on, and download it to the forum.

Welcome to the forum.

I wondering if you put into sport mode that it might have given you back your control of the drone.

Interference cannot make your drone fly off uncontrolled.
Recalibrating things on a properly working drone is unnecessary and doesn't do anything to prevent problems.

From your brief description, there are two possible causes but flight data and a few more details would be needed to determine what happened.
It's unlikely that there was anything wrong with the drone and the way it was used and the location was responsible.

Did your mission also include flying outside the warehouse? Just curious why you need FAA clearance. (Or was it actually “DJI clearance” that you needed?)

You have mainly 3 thing's that stabilize your craft in the airspace horizontally ...

1. That your AC have a free view of the sky & can lock on to enough GPS satellites & the IMU in the AC rank the positional accuracy from them as reliable enough.

2. If a GPS position can't be established as per above... that your AC's VPS sensors on the belly are low enough to a ground with a clear non reflective or moving pattern that is enough lit up.

3. That your AC's IMU know in which direction the AC is pointing so it can pinpoint which motors need to be commanded in order to counter a drift if the AC is affected from outside forces like wind.

From your description regarding the flight location ... all or some of the above 3 requirements may have been put out of play ... making your AC either without horizontal hold & breaking when releasing the sticks ... or not knowing the direction the AC was pointing due to that you powered on the AC with a magnetic disturbed compass.

Interference will not cause your AC to fly off in full speed ... it will at most swamp your AC-RC connection.

If you want to know the reason, start up by sharing the .TXT log from the flight ... it's stored in the mobile device you flew with. Read up here under section 3. on how to retrieve --> Mavic Flight Log Retrieval and Analysis Guide ... attach it then in a new post here.
