Calibrating the Compass
IMPORTANT: Always calibrate the compass in every new flight location. The compass is very sensitive
to electromagnetic interference, which can produce abnormal compass data and lead to poor flight
performance or flight failure. Regular calibration is required for optimal performance.
Do not calibrate your compass where there is any possibility of strong magnetic interference.
Sources of potential interference include magnetite, parking structures, and subterranean
metal structures
Do not carry ferromagnetic materials with you during calibration such as keys or cellular
phones.
Do not calibrate in direct proximity to large metal objects.
DO NOT calibrate indoors.
Calibration Procedures
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.
