speed, etc. If the airplane demonstrates satis- 
factory dihedral effect for these conditions of 
flight, certain exceptions can be considered 
when the airplane is in the takeoff and landing 
configuration. Since the effects of flaps and 
power are destablizing and reduce the dihedral 
effect, a certain amount of negative dihedral 
effect may be possible due to these sources. 
The deflection of flaps causes the inboard 
sections of the wing to become relatively more
