The U.S.
Federal Aviation Administration (FAA) and Europe's Joint Aviation
Authorities (JAA) have certified the Boeing 717-200's first major
upgrade to the airplane's flight control computer and flight management
system.
Both regulatory agencies certified the changes on Oct. 20, 2000, after a
rigorous 12-month follow-on program at the Boeing Long Beach Division.
Initial certification of the short-range twinjet occurred in September
1999.
"The 717 has gained an outstanding reputation for offering one of the
most advanced flight decks in the Boeing fleet," said Terry Beezhold,
director of the 717 Forward Cabin Integration Team. "The upgrade we have
certified will help make the aircraft even better, including boosting
its dispatch reliability, which has recently exceeded the program goal."
All functions originally envisioned for the airplane's Flight Management
and Autoflight systems now have been certified.
The updated Flight Management System (FMS) now includes Global
Positioning System capability, fuel predictions, and vertical guidance.
These features provide optimal fuel burn and automatic control to a
vertical path. The vertical path is constructed using airplane
performance data stored in the onboard computers. The FMS also
calculates take-off Vspeeds - the airspeed at which airplanes rotate or
lift off the ground - eliminating the need for the flight crew to review
charts and manually enter the information.
A data link function has been added to enable digital flight planning
communications between the airplane and ground air traffic control and
airline operational control.
Autoflight System updates include a reactive windshear function to help
flight crews detect and escape this potentially hazardous condition. A
Category lllb autoland capability, allowing an airplane to land when
visibility is extremely limited, is also available.
Chuck Finazzo, project leader of the follow-on certification, said the
upgrade package also contains other improvements and customer requested
changes based on customer inputs received during the first six months of
revenue service.
AirTran Airways, the launch customer, began 717-passenger service in
October 1999. Other current operators include Aerolineas Baleares,
Impulse Airlines, Olympic Aviation, and Trans World Airlines. |
