this is a bit second hand so don’t flame me.
i know that lots os people who train as pilots have done no aptitude testing, but early flying lessons might have the same effect cause if you don’t do very well you probably wont want a job like flying
but i understand that about half the guys who take the raf aptitude tests pass but only 10% of the girls do. i think the gapan tests are the same ones. the girls who pass are just as good as the guys – just our skills for things are different so there are fewer girls with what it takes to succeed as pilots than guys.
the obvious question is their bias in the tests? youll have to ask the raf that but the guy who told me this said that the raf have been trying to increase the numbers of girls they recruit for ages and have tried altering the tests and lowering the pass mark for girls and anything else but come up with the same answer all the time.
