last resort--
re: the question about recovery from flat spin--
with my limited knowledge, if i find myself strapped to an aircraft that appears to have a mind of its own and everything else i have tried doesn't work, i will put the gear down.
that might put enough drag into the equation to break the stalemate.
i read that the pilot of an uncontrollable 727 at altitude had tried everything else he knew (he was an aerobatic pilot); put the gear down as a last resort. the china 747 experienced such g-forces that the uplocks failed and the gear came down and they both lived to tell the tale.
admittedly not related to the thread's title.
and will respect any feedback.
