Flight controllers must report the type of the vehicle on which they are mounted (e.g. MAV_TYPE_OCTOROTOR). All other components must report a value appropriate for their type (e.g. a camera must use MAV_TYPE_CAMERA). Generic micro air vehicle Fixed wing aircraft. Quadrotor Coaxial helicopter Normal helicopter with tail rotor. Ground installation Operator control unit / ground control station Airship, controlled Free balloon, uncontrolled Rocket Ground rover Surface vessel, boat, ship Submarine Hexarotor Octorotor Tricopter Flapping wing Kite Onboard companion controller Two-rotor Tailsitter VTOL that additionally uses control surfaces in vertical operation. Note, value previously named MAV_TYPE_VTOL_DUOROTOR. Quad-rotor Tailsitter VTOL using a V-shaped quad config in vertical operation. Note: value previously named MAV_TYPE_VTOL_QUADROTOR. Tiltrotor VTOL. Fuselage and wings stay (nominally) horizontal in all flight phases. It able to tilt (some) rotors to provide thrust in cruise flight. VTOL with separate fixed rotors for hover and cruise flight. Fuselage and wings stay (nominally) horizontal in all flight phases. Tailsitter VTOL. Fuselage and wings orientation changes depending on flight phase: vertical for hover, horizontal for cruise. Use more specific VTOL MAV_TYPE_VTOL_DUOROTOR or MAV_TYPE_VTOL_QUADROTOR if appropriate. Tiltwing VTOL. Fuselage stays horizontal in all flight phases. The whole wing, along with any attached engine, can tilt between vertical and horizontal mode. VTOL reserved 5 Gimbal ADSB system Steerable, nonrigid airfoil Dodecarotor Camera Charging station FLARM collision avoidance system Servo Open Drone ID. See https://mavlink.io/en/services/opendroneid.html. Decarotor Battery Parachute Log OSD IMU GPS Winch Generic multirotor that does not fit into a specific type or whose type is unknown These flags encode the MAV mode. 0b10000000 MAV safety set to armed. Motors are enabled / running / can start. Ready to fly. Additional note: this flag is to be ignore when sent in the command MAV_CMD_DO_SET_MODE and MAV_CMD_COMPONENT_ARM_DISARM shall be used instead. The flag can still be used to report the armed state. 0b01000000 remote control input is enabled. 0b00100000 hardware in the loop simulation. All motors / actuators are blocked, but internal software is full operational. 0b00010000 system stabilizes electronically its attitude (and optionally position). It needs however further control inputs to move around. 0b00001000 guided mode enabled, system flies waypoints / mission items. 0b00000100 autonomous mode enabled, system finds its own goal positions. Guided flag can be set or not, depends on the actual implementation. 0b00000010 system has a test mode enabled. This flag is intended for temporary system tests and should not be used for stable implementations. 0b00000001 Reserved for future use. These values encode the bit positions of the decode position. These values can be used to read the value of a flag bit by combining the base_mode variable with AND with the flag position value. The result will be either 0 or 1, depending on if the flag is set or not. First bit: 10000000 Second bit: 01000000 Third bit: 00100000 Fourth bit: 00010000 Fifth bit: 00001000 Sixth bit: 00000100 Seventh bit: 00000010 Eighth bit: 00000001 Uninitialized system, state is unknown. System is booting up. System is calibrating and not flight-ready. System is grounded and on standby. It can be launched any time. System is active and might be already airborne. Motors are engaged. System is in a non-normal flight mode (failsafe). It can however still navigate. System is in a non-normal flight mode (failsafe). It lost control over parts or over the whole airframe. It is in mayday and going down. System just initialized its power-down sequence, will shut down now. System is terminating itself (failsafe or commanded). Component ids (values) for the different types and instances of onboard hardware/software that might make up a MAVLink system (autopilot, cameras, servos, GPS systems, avoidance systems etc.). Components must use the appropriate ID in their source address when sending messages. Components can also use IDs to determine if they are the intended recipient of an incoming message. The MAV_COMP_ID_ALL value is used to indicate messages that must be processed by all components. When creating new entries, components that can have multiple instances (e.g. cameras, servos etc.) should be allocated sequential values. An appropriate number of values should be left free after these components to allow the number of instances to be expanded. Target id (target_component) used to broadcast messages to all components of the receiving system. Components should attempt to process messages with this component ID and forward to components on any other interfaces. Note: This is not a valid *source* component id for a message. System flight controller component ("autopilot"). Only one autopilot is expected in a particular system. Id for a component on privately managed MAVLink network.

Component handling TUNNEL messages (e.g. vendor specific GUI of a component). System control does not require a separate component ID. Instead, system commands should be sent with target_component=MAV_COMP_ID_ALL allowing the target component to use any appropriate component id. Deprecated, don't use. Component for handling system messages (e.g. to ARM, takeoff, etc.). The heartbeat message shows that a system or component is present and responding. The type and autopilot fields (along with the message component id), allow the receiving system to treat further messages from this system appropriately (e.g. by laying out the user interface based on the autopilot). This microservice is documented at https://mavlink.io/en/services/heartbeat.html Vehicle or component type. For a flight controller component the vehicle type (quadrotor, helicopter, etc.). For other components the component type (e.g. camera, gimbal, etc.). This should be used in preference to component id for identifying the component type. Autopilot type / class. Use MAV_AUTOPILOT_INVALID for components that are not flight controllers. System mode bitmap. A bitfield for use for autopilot-specific flags System status flag. MAVLink version, not writable by user, gets added by protocol because of magic data type: uint8_t_mavlink_version Version and capability of protocol version. This message can be requested with MAV_CMD_REQUEST_MESSAGE and is used as part of the handshaking to establish which MAVLink version should be used on the network. Every node should respond to a request for PROTOCOL_VERSION to enable the handshaking. Library implementers should consider adding this into the default decoding state machine to allow the protocol core to respond directly.
