Abstract: A vertical takeoff and landing vehicle which includes an allocation block that receives a set of desired forces or desired moments and a health metric associated with at least one of: (1) a motor controller or (2) a rotor that operates in a vertical takeoff and landing mode at least some of the time. A command signal is determined per a first manner that attempts to satisfy both the set of desired forces or desired moments and the health metric. If the command signal is unable to be determined in the first manner, a second manner is used that prioritizes flight control associated with one or more of a roll axis or a pitch axis over flight control associated with a yaw axis where the axes are mutually orthogonal. The command signal is output to the motor controller that controls the rotor using the command signal.

Abstract: Sensor data is received from an inertial measurement unit on a vehicle. An observed attitude and an observed attitude rate of the vehicle are determined based on the sensor data. Using a model associated with a vehicle failure mode, an expected attitude and an expected attitude rate of the vehicle are determined. A malfunctioning rotor is determined based on the observed attitude, the observed attitude rate, the expected attitude, and the expected attitude rate. In response to identifying the malfunctioning rotor, a responsive action is performed, including by updating a geometry matrix so that at least one non-malfunctioning rotor in the plurality of rotors compensates for the malfunctioning rotor.

Abstract: A first hand control controls an altitude of a vertical takeoff and landing (VTOL) aircraft; the movement of the VTOL aircraft within a plane defined by a roll axis and a pitch axis is independent of the first hand control. The first hand control is provided on a first hand side of a pilot's seat included in the VTOL aircraft. A second hand control controls the movement of the VTOL aircraft within the plane defined by the roll axis and the pitch axis; the altitude of the VTOL aircraft is independent of the second hand control. The second hand control is provided on a second hand side of the pilot's seat that is opposite from the first hand side.

Abstract: A flight-time variable associated with an aircraft is determined including by determining the flight-time variable while the aircraft is flying. It is determined whether the aircraft is airworthy based at least in part on the flight-time variable. In response to determining that the aircraft is not airworthy, the aircraft is automatically landed.

Abstract: An inner middle rotor is rotated while an inner front rotor, an inner back rotor, and an outer rotor are not rotated. The inner middle rotor is surrounded by the inner front rotor, the inner back rotor, the outer rotor, and a fuselage. After rotating the inner middle rotor while not rotating the inner front rotor, the inner back rotor, and the outer rotor, the inner middle rotor, the inner front rotor, the inner back rotor, and the outer rotor are simultaneously rotated.
