Honeywell certifies Pegasus FMS on B767-400 and A340

Honeywell's Pegasus flight management system (FMS) received FAA type certification on the new Boeing 767-400ER aircraft, which was shown at its first international air show at Farnborough last week.

The Pegasus system also received European Joint Airworthiness Authority (JAA) certification on the Airbus A340. The certification follows closely on a successful Airbus round-the-world test flight of Future Air Navigation System (FANS) data link using an A340-300 test bed. The Pegasus software supports the full flight regime with all long-range functions for both lateral guidance and flight planning as well as vertical guidance and performance functions in a dual system configuration.

This latest certification highlights the next-generation FMS, providing airlines with new capabilities and performance features to take advantage of the emerging Communications, Navigation, Surveillance/Air Traffic Management (CNS/ATM) operating environment. The intention is to support not only Boeing's new 767-400 aircraft, but to provide increased FMS capability to all 757 and 767 operators.

Features on the new Pegasus FMS includes

  • flight path angle, vertical bearing and vertical speed functions, which are displayed on multifunction control display unit (MCDU) during descent to enhance situational awareness;
  • wind trade-off step climbs, which save time and fuel;
  • Required Navigation Performance (RNP) values in the navigation database to improve operational efficiency;
  • RF (Radius-to-a-Fix) legs in the navigation database to allow aircraft to fly an arc procedure without ground-based navigation aids;
  • back-up radio tuning to provide the capability to manually tune radios via the MCDU, de-cluttering the panel and saving weight.
  • full back-up navigation in the multi-function control-display units (MCDUs);
  • GPS primary means navigation;
  • dual electronic flight instrument system (EFIS) display of all flight plans; and
  • an improved BITE system.
