intersection of the positive limit load factor 
and the line of maximum, positive lift capa- 
bility. The airspeed at this point is the 
minimum airspeed at which the limit load 
can be developed aerodynamically. Any air- 
speed greater than pomt A provides a positive 
lift capability sufficient to damage the air- 
plane; any airspeed less than point A does 
not provide Positive lift capability sufficient to
