Spinexes

CFS spinex visits 1986 to F4 , Lightning and Jag stations. I concur that the aim was to remind FJ pilots of spin/departure symptoms and how disorientating a spin can be especially if it went oscillitory. Achieved that by judicious use of in spin aileron (not supposed to but much more useful for the exercise) and noting the exchange of energy between the gyros (wing vs fuselage B over A ratios anyone?). pilots supposed to recite their aircraft spin recovery actions whilst we would try to facilitate the recovery to coincide with their final correct action. Last exercise was to get them to fly the entry, maintain the spin whilst reciting (but not doing!) their aircraft recovery drill. As said earlier this could produce some very interesting spins if they could not stop themselves from doing their own thing! Best performers in the cockpit?F4 navs..word perfect. Gnat as student in mid 70s, only did slow downs, no slip, unload and power out; Hunter, no spinning even demoed but fro personal experience it handled like a big JP loads of warning buffet, centralising always got things on track. Jag? Departed it once at LL, hard roll towards the bounce and pulled at same time, an absolute no no; aircraft calmly rolled back left to upright whilst I had nearly full right stick/spoiler...centralised bl@#dy fast and flew SandL for 30 secs to calm down. Used to demo spin entry in JP to FJ crews by inducing wing drop stall then trying to pick up down going wing with aileron. Although quite slow you could see the roll one way stick the other symptom of incipient departure. ‘Only second to Live’ by Duncan Hadley is an excellent book about the early days of flying and the discovery of spin recovery actions (partly by accident) and the subsequent development of theory and instruction in this part of the envelope.
