I need to resurrect this just to clarify a point!
Previously, I said: "To stop your head from hurting when you clatter it on the canopy during all the flick manoeuvres we're no longer allowed to do 'cos some halfwit doesn't know how to write an aircraft manual!!!!!"
It was - quite rightly - pointed out to me that this was a tad ambiguous. What the words "aircraft manual" refer to is the Grob Manufacturer's Flight Manual. The Aircrew Manual, produced by the RAF, is a good document with which I have no problems. Happy now RM??
