Very interesting. During my undergraduate apprenticeship at Warton , in about 1970, I spent 3 months in the Flight Test department. The Lightning spinning trials were over, and I helped prepare graphs from the telemetry tapes. A number of Lightnings had been lost during medium level high g tail chase manoeuvres. Recovery was achieved by “letting go” of the control column…..that’s how it was put to me, but it was probably by centralising the column, and not by trying to recover by pilot input. The A/C would roll and when unloaded, control was regained. If mishandled, then the ensuing spin , had such a high rate of descent that from medium level….15,000 ft…that recovery was impossible in the available height. The test aircraft was fitted with a tail chute .
My instructor on my Airborne Forward air controllers course had the most amazingly perfect set of teeth. His Jaguar , in a quote "controversial" configuration had departed low level and he was obliged to remove himself from the situation courtesy of Messers Martin and Baker unfortunately leaving part of his Jaw and teeth behind!😱 His recovery was a tribute to both the aforementioned designers and the NHS.
Was ground crew at Lossie 84 and nabbed a jolly in the backseat of 226OCU Jaguar, loved every second of low level flying through Scotland. Awesome memories 😁
The chief pilot uses the term "high incidence" multiple times - he knows what he's talking about I'm sure. Often of course "high incidence" equates to a high AoC. The term "high incidence" is used for a low speed stall at high altitude.
