9.1 COMPASS CALIBRATION
Compass calibration is required before the first time flight, otherwise the system may not work
properly. The compass is very sensitive to electromagnetic interference which can cause
abnormal compass data and lead to poor flight performance or even flight failure. Regular
calibration enables the compass is in optimum performance.
