Beginning this October, new-build Boeing 737 jetliners will use GE Aviation Systems flight-management system (FMS) update 10.8 software. The change provides increased navigation database capacity (with room for growth) and accommodates different performance of 737s fitted with winglets. FMSs allow operators to meet required navigation performance standards for separation from the ground or other aircraft. By providing positional data to air-traffic management (ATM) agencies, the equipment permits aircraft to descend to lower altitudes in reduced visibility.
GE’s system is part of Eurocontrol’s “controlled FMS time of arrival (CTA)” ATM system-integration studies (CASSIS). The project is testing the potential for CTA to support arrivals management and thus improve airline and airport efficiencies. First CASSIS flight trials have been conducted at Stockholm Arlanda airport to see how well CTA works in terminal area operations. The FMS equips additional airliner types and military aircraft.
