Component that manages autonomy behaviors/subsystems above and beyond those implemented by the autopilot (MAV_COMP_ID_AUTOPILOT1). Managed subsystems could include Kalman Filters integrating sensors not interfaced to the autopilot, obstacle avoidance, path planning, vision systems and other sensors. The autonomy engine may implement a superset of the functionality available from other seldom-used components such as MAV_COMP_ID_OBSTACLE_AVOIDANCE, MAV_COMP_ID_PATHPLANNER, MAV_COMP_ID_OBSTACLE_AVOIDANCE, and MAV_COMP_ID_ONBOARD_COMPUTER.

+ A single component which presents many attributes and capabilities which prevent it from being binned into any of the other IDs in this enum. For context, refer to the monolithic generic component example in air-iop documentation release 1.2

Bitmask of (optional) autopilot capabilities (64 bit). If a bit is set, the autopilot supports this capability.
