I then did a normal take off, no flap, no brakes, rotate at 55 kts and got off in exactly the same distance, however 50 ft came up at about 1300 ft which I was expecting. I was suprised that the no flap t/o run was the same. Runway is hard, wind was absolutely calm, temp around 0C. Anybody explain or is this normal? Incidentally the short field landing at 65 kts approach, full flap and fairly heavy braking was around 1000 ft from 50 ft.
This should not be surprising as the POH specifically mentions that for a short field takeoff, no obstacle: quote
use of partial flap does not decrease the minimum ground roll, therefore, leave the flaps up or lower the flaps to 25 degrees as desired unquote
