British Aerospace Regional Aircraft presented some options for potential future developments of the Avro RJ, designated the Avro RJX, at the European Regions Airline Association’s annual meeting. Pratt & Whitney’s PW308 and the Allied Signal AS907 are being studied as potential replacements for the RJ’s Allied Signal LF507 engines. BAe is seeking to reduce fuel burn by 15 percent, lower direct maintenance costs by 20 percent, and cut empty weight by 900 Kg. Aside from improving operating efficiency, these changes would also reduce navigation and landing charges. Upgrades to the Avro RJ flight deck are also being studied. RJX deliveries could begin in late 2001.
