in experienced hands there is no other airplane that could beat the IV-P
for comfort and economy
my  IV-P  stalls at 76  KTS straight ahead flies straight hands off and when in a turn
will continue level for 360 degrees
i have been unable to do that on any other airplanes including the docile 182
it does honest 235 knots at altitude and when LOP I burn 16.5 g/hr with a range
of 1250 miles  a large baggage a/c and great instrument platform
come up with something similar

Have you ever wondered why they don't make the IVP's any more?

Is it just me or does anyone else find it just a bit disturbing that the Lancairs have such "fearsome" stall characteristics ?

Bruce,
 
Au contraire, mon ami......
 
The Advanced Systems AOA does not require stalling the aircraft.  Read for theory and calibration:

Every single AOA I know of requires you to stall the aircraft to calibrate the AOA.

One of the main reasons all of us IV-P owners have a hell of a time getting insurance for our airplanes is because too many guys "explored" the stall characteristics of their airplane (and for many it was their last flight).   I fly another airplane that can fly comfortably at 60 degrees AOA, and have a good bit of time as an operational test pilot, but I will never stall my IV-P intentionally.  Or even get close.  Like Colyn and John, I'm 120 on downwind, 110 at the base turn and 100 on final until the runway is assured.   Unless we fly the pattern at 8000 feet AGL, a stall will probably be fatal for any of us.  Please don't be the next one to prove this point !
