Power-by-wire (PBH) Is a key element under subsonic transport flight systems technology with potential savings of over 10 percent In gross take off weight and In fuel consumption compared to today's transport aircraft. The PBH technology substitutes electrical actuation In place of centralized hydraulics, uses Internal starter-motor/generators and eliminates the need for variable engine bleed air to supply cabin comfort. The application of advanced fiber optics to the electrical power system controls, to built-In-test (BITE) equipment, and to fly-by-light (FBL) flight controls provides additional benefits In lightning and high energy radio frequency (HERF) Immunity over existing mechanical or even fly-by-wire controls. This paper will review the program plan and give a snapshot of the key technologies and their benefits to all future aircraft, civil and military.
