The Battle of Britain Was The First Defeat For The German Luftwaffe.

[Kurfürst]

How many RAF pilots were considered "A" Squadron category, ie. fit for combat, and how many "B" and "C", ie. unfit for combat and essentially only existing on paper?

Considering that RAF started the battle with about 800 fighters, and lost as destroyed about 1100 during the Battle, it would seem the initial pool of pilots was lucky if he even survived the battle with an attrition over 100%.. how many were considered fit for operations out of these hordes of new pilots with six weeks of traning? I doubt if more than a third.
