Europa-List: Flap extension

[Frank Mycroft <frankm@clara.net>]

It is my recollection that in the early stages of development of the 
Europa (when almost any degree of flap could have been designed in) it 
was found that anything more than 25degrees increased drag but did not 
increase lift.  In other words more flap could give you a steeper 
approach, but would not reduce the stalling speed.
