        The general system state. If the system is following the

        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
        by path/waypoint planner). The NAV_MODE defined the current
        flight state: LIFTOFF (often an open-loop maneuver), LANDING,
        WAYPOINTS or VECTOR. This represents the internal navigation
        state machine. The system status shows wether the system is
        currently active or not and if an emergency occured. During
        the CRITICAL and EMERGENCY states the MAV is still considered
        to be active, but should start emergency procedures
        autonomously. After a failure occured it should first move
        from active to critical to allow manual intervention and then
        move to emergency after a certain timeout.

                The general system state. If the system is following the MAVLink
                standard, the system state is mainly defined by three
                orthogonal states/modes: The system mode, which is
                either 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 by
                path/waypoint planner). The NAV_MODE defined the
                current flight state: LIFTOFF (often an open-loop
                maneuver), LANDING, WAYPOINTS or VECTOR. This
                represents the internal navigation state machine. The
                system status shows wether the system is currently
                active or not and if an emergency occured. During the
                CRITICAL and EMERGENCY states the MAV is still
                considered to be active, but should start emergency
                procedures autonomously. After a failure occured it
                should first move from active to critical to allow
                manual intervention and then move to emergency after a
                certain timeout.

                The general system state. If the system is following the MAVLink
                standard, the system state is mainly defined by three
                orthogonal states/modes: The system mode, which is
                either 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 by
                path/waypoint planner). The NAV_MODE defined the
                current flight state: LIFTOFF (often an open-loop
                maneuver), LANDING, WAYPOINTS or VECTOR. This
                represents the internal navigation state machine. The
                system status shows wether the system is currently
                active or not and if an emergency occured. During the
                CRITICAL and EMERGENCY states the MAV is still
                considered to be active, but should start emergency
                procedures autonomously. After a failure occured it
                should first move from active to critical to allow
                manual intervention and then move to emergency after a
                certain timeout.

                Onboard parameters are stored as key[const char*] ->

                other component (such as the GCS) without the need of

                different autopilots. See also
