Any parts of the Trident contributed to the 146 ?
Oh the years I have waited for this trivia question.
IIRC the ‘Q’ pot was the same in both aircraft, and possibly the same design as in the Comet (and even the Sea Vixen).
Greater contributions from the Trident were in the experience gained by the design team, the technical and operational certification, and the practical application of the airworthiness philosophies of triplex systems. These were major advances in modern airworthiness.
Lessons learnt from the Trident – the 146 was strong, well built, also like the 125. The 146 had sparkling field performance in comparison ;-)
The two crew certification of the BAe146 was ‘a first’ in that it had to follow precedence set by the BAC 1-11 and DC 9 types, particularly with the FAA – but they had failed to consider that a two crew, 4 eng aircraft, could exist.
