Force Unlock
I. Principle
INAV uses a multi-layer safety check mechanism to ensure the aircraft unlocks in a safe state. If certain conditions are not met (such as navigation not ready, sensor anomalies, throttle not at zero etc.), the flight controller will prevent unlocking.
Force Unlock is mainly used to ignore the "Navigation is in a safe state" check item, allowing the aircraft to unlock without a GPS signal. Other unlock check items still need to be manually checked and cannot be bypassed with force unlock.
