This topic is fraught with danger.....Bit like skipping through a minefield.
I was actually taught through the PPL by a female instructor, who was:
1. A great instructor
2. A good friend
3. A lady.
The individual in question is now an FO for a major airline!
Abilty and talent as HA said is the key.....
And I must have learned something from her as Im still here.
Id hate to see the days when quotas replace ability as the norm....
For the rest of the girls Ive met, some have been great aviators and great PEOPLE. Some didn't need to be able to fly except maybe undo one......
But then again its really the individual. It certainly aint brain power that seperates the sexes, maybe a little physical strength and endurance...For those jobs requiring physical prowess a bloke will generally be better..
And I so advise...
