Phantom 4-Calibrating the Compass
Only calibrate the compass when the DJI GO app or the status indicator prompt you to do so. Observe the following rules when calibrating your compass:
Choose an open area to carry out the following procedures.
1. Ensure that the compass is calibrated. If you did not calibrate the compass as part of your pre-flight preparations, or if you have moved to a new location since the last calibration, tap the Aircraft Status Bar in the app and select “Calibrate”, then follow the on-screen instructions.
2. Hold the aircraft horizontally and rotate 360 degrees. The Aircraft Status Indicators will display a solid green light.
3. Hold the aircraft vertically, with nose pointing downward, and rotate it 360 degrees around the center axis. Recalibrate the compass if the Aircraft Status Indicator glows solid red.
4. Re-calibrate the aircraft if the aircraft status indicators blink red.
When to Recalibrate
1.When compass data is abnormal and the Aircraft Status Indicator is blinking green and yellow. 2.When flying in a new location or in a location that is different from the most recent flight. 3.When the mechanical or physical structure of the Phantom 4 has been changed.
4.When severe drifting occurs in flight, i.e. Phantom 4 does not fly in straight line.
