There is provided a system for controlling at least first and second engines of an aircraft, comprising a common controlling unit configured to convert data representative of a thrust command transmitted by an actuating element controllable by a pilot or by an auto-throttle of the aircraft, into: (a) at least one first command usable by a controller of the first engine for controlling its operation based at least on said first command, and (b) at least one second command usable by a controller of the second engine for controlling its operation based at least on said second command, wherein said common controlling unit is operable to perform said conversion based at least on data representative of a level of operability of each engine, thereby making each engine to either comply with said thrust command or to operate differently from said thrust command, based at least on its level of operability.

A control device controls an electric drive system mounted on an electric vertical takeoff and landing aircraft with a rotor, and including a drive motor that turns the rotor. The control device controls the electric drive system to operate selectively in any one operation mode of at least two operation modes: a normal mode and a functional test mode. In the normal mode, the control device controls the drive motor in accordance with a command from a body control device that controls the flight of the electric vertical takeoff and landing aircraft. In the functional test mode, the control device controls the drive motor in accordance with a command sent from outside according to a functional test program, or in accordance with the functional test program preset in the control device.

Methods, apparatus, systems, and articles of manufacture are disclosed for flight control prioritization. An example apparatus includes a thrust state determiner to determine a first thrust margin between a first limit of first available power for first rotors of a rotorcraft and a first thrust state associated with the first rotors, determine a second thrust margin between a second limit of second available power for second rotors of the rotorcraft and a second thrust state associated with the second rotors, and identify the first thrust margin or the second thrust margin as a selected thrust margin based on a vertical control profile of the rotorcraft, and a command generator to determine a first vertical control command based on the selected thrust margin and a second vertical control command, the second vertical control command being executed by the rotorcraft, and control the rotorcraft based on the first vertical control command.

A rotor control device for performing attitude control of a fuselage of an aircraft includes a VTOL rotor control unit for controlling each rotor based on a roll moment command value, a pitch moment command value, and a yaw moment command value. When the magnitude of the roll moment command value or the magnitude of the pitch moment command value is equal to or greater than a threshold, the VTOL rotor control unit controls each rotor without using the yaw moment command value.
