Randy,
 
Interesting.
 
In the pattern, level, lo pwr and dirty, 1.3 x 61=3D79 KIAS.=  =20 A 30 degree banked turn raises the stall speed about 4 kts.  Not much = of a=20 margin if operating at or below 85 KIAS.
 
Engine failure on take off after flaps and gear cleaned up - level fli= ght -=20 1.3 x 72 =3D 93 and a 30 degree turn raises that to 98 KIAS.  I think = that's=20 why I liked to climb out at an excess of 130 KIAS.
