Hi microburst8265,
My main reply related to stalling the 'right way up', i.e. normal flight.
The inverted flight footnote related to flying in a Chipmunk (DHC1), and it still remains a mystery to me why, with or without flaps, the stall speed was the same when inverted. By all reasoning the stall speed should have been higher (when inverted), with the flaps Down (or Negative Down). All of the Inverted stall speeds were noticeably higher than for normal flight, which would be expected. Another Chipmunk oddity was that recovery from an inverted spin was inevitably faster than for 'right way up', perhaps because the fin and rudder received direct 'unblanketed' air flow.
Regards,
Old Smokey
