[35], According to Woods, a significant opportunity that may have enabled the Trident to catch up with the 727 was lost during the 1960s in the form of two competitions for a maritime patrol aircraft; a NATO design competition to replace the Lockheed P-2 Neptune, and Air Staff Requirement 381, which sought a replacement for the Royal Air Force's piston-engined Avro Shackleton. #ga-ad {display: none;} Instead of attempting to replace the three engines with a completely different type, which would have been difficult with one engine buried in the tail, Hawker Siddeley's engineers decided to add a fourth engine in the tail, the tiny Rolls-Royce RB162 turbojet, fed from its own intake behind a pair of movable doors. 151 relations. [16], In March 1959, BEA, which had become concerned by a recent decline in passenger growth, concluded that the DH.121's payload-range capacity could be too great for their needs and petitioned de Havilland to reduce the scale of the design to suit their revised projections. China regarded it as the best aircraft the west had ever produced.. de Havilland DH-121, Airco DH-121) first flew one year before Boeing 727; first instrument landing; first This was the beginning of their phasing out of the Hawker Siddeley Trident 3B.

[39] Wood summarised the importance of this prospective development as: "For the Trident programme, the RB.177 would have been a God-send". Its designers felt this configuration offered a trade-off between cruising economy and take-off safety in case of an engine failure; moreover, the BEA specification had called for "more than two engines". [16], Six months following BEA's request, de Havilland and the airline came to an agreement on the downsized DH.121.
