I just flew my Inspire 2 today for the first time with the CrystalSky monitor. I wanted to do a compass calibration with the Inspire but it does not seem to be avialable in the status window like it usually is with my iPad.
Is there somewhere else I can access this within the CrystalSky versoin of the app?

compass

There is an option in the settings menu.  Here is a screen shot.

The post by rparge is the compass calibration of CrystalSky.
The option of compass calibration in DJI Go 4 is grey or cannot be found? Could you please post a picture of Aircraft Status?

Yes, the Status screen is where I'm trying to access the Compass Calibration like I did on my iPad.

Right, there are two compass calibrations.
One is for the CS, the other is for the aircraft.
If you want the aircraft compass calibration, access it by hitting the
Quad icon > Advanced > Sensor Sate > Compass.
Is this what you were looking for?

That was it!
Thanks for your help.
