15 Apr 2009 - FAA Certifies GEs Flight Management Software Update 10.8

GRAND RAPIDS, Mich. - (Business Wire) GE Aviation announces the Federal Aviation Administration (FAA)

certification of the flight management system (FMS) software Update 10.8 for Boeing Next-Generation 737s. The

new software is standard fit for all 737 production airplanes starting February 2009.

GEs flight management system is an example of how were helping operators to reduce costs, while improving

performance as it relates to on-time arrivals and less fuel, emissions, noise and less through-life cost, saidLorraine Bolsinger, president and CEO of GEs Aviation Systems. We continue to work with customers and

government bodies around the world in order to implement the technology and procedures necessary to reduce an

airplanes impact on the environment. GEs flight management system optimized descent is one of the most

recent products to become ecomagination qualified.

The FMS 10.8 software update provides improved operation, increased navigation data base size for storage of a

worldwide size data base with 95% spare memory for growth, and supports the APB Blended Winglet installation

on all 737 Classic and Next-Generation airplanes. The FMS provides precision navigation compliant with the

Required Navigation Performance (RNP) standards that allow reduced separation from terrain and other aircraft.

RNP approach procedures also allow the aircraft to descend to lower altitudes when flying on instruments in

reduced visibility conditions. The FMS provides output of the aircraft 4-dimensional trajectory to be used by Air

Traffic Control to enable integrated air-ground operations.

GE also provides other versions of its flight management systems for the Airbus A320/330/340, Boeing 767

Tanker, and U.S. Navy E-6 aircraft, the USAF E-4 and C-130, UK C-130, Spanish Air Force C-130s, C-130 AMP,

UK Nimrod 2000, IL-96. GEs FMS software will also be on the U.S. Navy P-8A aircraft which is currently in

development. GE certified their first flight management computer in November 1984.
