Abstract: Disclosed is a brake system for aircraft that uses a control unit that is configured to control actuators at each wheel using one channel operating an associated brake control module, and other actuators at the same wheel using a second module operated completely independently using a second module. The use of the first and second groups of actuators are alternated periodically, e.g., for each flight.

Abstract: A pneumo-mechanical landing gear deployment system includes a dual-stage handle operatively connected to a pressurized tank, a nose landing gear pneumatically connected to the pressurized tank, and a main landing gear pneumatically connected to the pressurized tank. Actuation of the dual-stage handle to a first position opens the pressurized tank thereby deploying the nose landing gear. Actuation of the dual-stage handle to a second position causes further opening of the pressurized tank thereby deploying the main landing gear. The system may be employed as a backup landing gear deployment system in the case of a primary landing gear system failure.
