The Flight Deck
The flight deck of the 757-300, like that of the 757-200, is designed
for two-crew member operation and furnished with digital electronic
displays.
A
computerized, fully integrated flight management system (FMS) provides
for automatic guidance and control of the airplane from immediately
after takeoff to final approach and landing. Linking together digital
processors controlling navigation, guidance and engine thrust, the FMS
assures that the aircraft flies the most efficient route and flight
profile for reduced fuel consumption, flight time and crew workload.
The pilot and the copilot each have a pair of electronic displays for
primary flight instrumentation and navigation. One display shows an
electronic attitude director indicator and the other an electronic horizontal
situation indicator.
Several flight deck improvements have been made on both the 757-300
and the 757-200.
- The Pegasus flight management computer (FMC) and an enhanced engine
indication and crew alerting system (EICAS) are now standard on both
757 models.
- With the Pegasus FMC, operators can choose optional software that
enables elements of the future air navigation system (FANS). FANS
functions provide operators with the ability to use advanced systems,
such as global positioning system (GPS) sensors and satellite communications
(SATCOM), to take full advantage of new communication, navigation
and air traffic management systems for more efficient routing and
decreased trans-oceanic traffic separation.
- The EICAS upgrade replaces existing computers with enhanced devices
that are software loadable. The new EICAS has improved built-in test
equipment (BITE) functions that allow for improved self-diagnosis
of faults in a more readable format. On-board software loading allows
operators to use the same EICAS computer as a replacement on any 757
or 767. That reduces the required inventory of spare parts.
- The 757 has an enhanced ground proximity warning system (EGPWS),
intended to reduce controlled flight into terrain,
- A new software-loadable flight control computer (FCC) and an enhanced
windshear warning system are also available.
- The 757-300 also incorporates the latest technology air data/inertial
reference system (ADIRS).
