        LOCKED (motors shut down and locked), MANUAL (system under RC
        control), GUIDED (system with autonomous position control,
        position setpoint controlled manually) or AUTO (system guided

        to be active, but should start emergency procedures
        autonomously. After a failure occured it should first move
