Chox how can your europa have a definitive POH when choices of engines etc ( and therefor all up weight/C of G etc ) will have a profound effect on stall speed and therefor approach speed ?
I did not say it had a defintive POH I was agreeing that the various speeds are recorded for MY SPECIFIC aircraft at the time the aircraft was being test flown.
I regularly (about every three months) check the recorded stall speeds against current performance - they are still same as initally recorded (within the accuracy of my ASI) and these are the speeds I use for calculating approach speed (1.3 times stall speed in landing configuration - full flap, prop in climb mode)
