Abstract: A signal associated with a motor is obtained where the motor is included in a aircraft that has flight capabilities. A motor wear metric that represents an amount of wear experienced by the motor is determined based at least in part on the signal. It is determined, at a flight computer that is included in the aircraft, whether to restrict the flight capabilities of the aircraft based at least in part on the motor wear metric. The flight capabilities of the aircraft are restricted in the event it is so determined.

Abstract: A landing zone indicator system which includes a battery that is configured to power a controller and a human vision output device, a controller that is configured to control human-visible light that is output by the human vision output device, and a human vision output device where the human-visible light output by the human vision output device generates an illuminated landing zone for a vertical takeoff and landing (VTOL) vehicle.

Abstract: In an embodiment, a system for air cooling in a wet environment includes a propeller coupled to a vehicle capable of at least one of: taking off from and landing on water. The system includes a battery configured to power the propeller, a float configured to hold the battery, and a flap in the float. The flap is configured to open in response to air pressure to permit airflow into the float to cool the battery.

Abstract: In an embodiment, a system for generating a motor wear metric includes a process configured to obtain a signal associated with a motor of an aircraft, determine a motor wear metric based at least in part on the obtained signal, and output information about motor wear based at least in part on the determined motor wear metric. The system includes a memory coupled to the processor and configured to provide the processor with instructions and store the determined motor wear metric.

Abstract: In an embodiment, a system for battery shifting for center of gravity (CG) control includes a battery holder and a controller. The battery holder is adapted to change between a first battery position and a second battery position in a vehicle. The battery holder being in the first position causes the vehicle to have a first CG and the battery holder being in the second position causes the vehicle to have a second CG. The controller is configured to move the battery holder into the first position at least some of the time when the vehicle is flying at a first angle such that the vehicle has a CG in a first vehicle location, and move the battery holder into the second position at least some of the time when the vehicle is flying at a second angle such that the vehicle has a CG in a second vehicle location.
