Abstract
An accelerometer based power control apparatus for use in an aircraft subsystem (where the subsystem may be a fire extinguishing system) utilizes an independent battery source. The battery is connected to the aircraft subsystem only during the flight of the aircraft by a positive indication of an associated accelerometer which closes a switch connecting the battery to the aircraft subsystem.
