Regulatory Authority absurdity
Not entirely on topic, so threads-drift permission> Thx. About 1981-ish (how old can I be? LOL) at AMH we were seeking the old 'Cat A' performance under CAA rules for departures from Battersea for the Mk1 A109.
It all got stymied by CAA (fancy that) so the pay-load wasn't worth the charter; their main concerns with the early A109 was reliability of the Allison 250-C20B. I did a hell of a lot research, and secured a ton of data from George Mayo, then boss of DDA Allison to prove the integrity of the engine
How surprised (and disgusted) was I to receive a patronising letter from CAA advising ".... two engines thus provide twice the chance of an engine failure." How can anyone work with that distorted perspective? - VFR
