Randy,
Interesting.
In the pattern, level, lo pwr and dirty, 1.3 x 61=79 KIAS.
A 30 degree banked turn raises the stall speed about 4 kts. Not much of a
margin if operating at or below 85 KIAS.
Engine failure on take off after flaps and gear cleaned up - level flight -
1.3 x 72 = 93 and a 30 degree turn raises that to 98 KIAS. I think that's
why I liked to climb out at an excess of 130 KIAS.
