For the Eighties and Beyond Available to Purchase

DELIVERY of the first of 12 Boeing 757's powered by Rolls‐Royce RB 211–535 E4 turbofans was made to Eastern Airlines in October and the aircraft entered service with the carrier a short while afterwards. This followed a comprehensive programme of testing which culminated in certification of the powerplant by the FAA. Flight testing included engine operating characteristics, in‐flight starts and general aircraft performance as well as flight deck electronic/engine compatibility and the collection of pertinent data for flight manual revisions. Eastern Airlines at present operates a fleet of fifteen RB 211–535 C powered 757's which will be retrofitted with the —535 E4. In the UK, Monarch Airlines' Boeing 757's will also be retrofitted with the new engines.
