The Avro RJX came one step closer to first flight on 24 January, when the first Honeywell AS977 engine was fitted to the prototype RJX-85, msn E2376, in the number four position. The engine arrived at Woodford the previous day. The entire engine assembly, comprising the AS977 engine, nacelle, and pylon installation has been designed as an integrated whole known as the Integrated Powerplant System (IPPS). It is being produced in a cooperative arrangement by BAE Systems, Honeywell, and GKN-Westland. Its development has experienced delays, postponing first flight by several months from the mid-late 2000 timescale originally envisaged. First flight is now expected to take place later this month, although it may slip further, into March. The first RJX-100, msn E3378, will follow a few months later.
