Directional Flicking?
LOMCEVAK
It always went the same way when balanced (ball or yaw string in the middle). It could be delayed by adverse rudder and induced earlier (and nastier) by high onset g as well as a little "pro" rudder - but always to the right as I recall. As I had about 2000hrs on the Fanta Can I was familiar with its vices in the stall, spin, flick department. Asymmetric fuel in tiptanks didn't have any great effect on either departure or spin characteristics - as long as it was within reason.
We had seen a couple of inverted spin ejectees (and I seem to recall Clive Blennerhasset was one - but may be wrong). Anyway I do recall that I got the message that inverted ejection under cycling g was a definite six months in hospital if you were lucky. I'm starting to lose it a bit now, but I think it had seat-top canopy breakers (no MDC, LDC for canopy jettison failure). As I vaguely recall there was some concern that under a neg g spin, the canopy might not go cleanly. It was a lethal canopy anyway. It decapitated a few in its time.
Always wondered how the Tucano front-seat ejectees made out with LDC spatter. That was one thick canopy in the front.
