Abstract
An aircraft includes a power source arranged to provide AC electrical power of varying frequency, and a brake cooling fan including an impeller which is driven by an electric motor powered by said AC electrical power for cooling brakes of the aircrafts wheels. The brake cooling fan has an operable mode when the frequency of said AC electrical power meets certain criteria indicating that the frequency of the AC power is suitable for powering the motor, and an inoperable mode to protect against unsuitable operation of the motor. The brake cooling fan may then be safely powered with AC power direct from a wild frequency power network on the aircraft without needing a power inverter or constant power supply generator.
