The Tay — A Rolls‐Royce Success Story

WITH most of the exacting Tay test programme completed — the programme is in fact ahead of schedule by 200 running hours, equating to four months in terms of cycles completed with certification targeted for June 1986. More than 85 Gulfstream IV aircraft powered by the Tay engine have now been ordered and the Fokker 100 short to medium haul jet, also Tay powered, has been selected by Swissair, KLM Royal Dutch airlines and USAir, representing 38 firm orders and 31 options. The Fokker 100 is expected to fly in mid 1986.
