I'm with Skater and Huey on this one:
There are specialist pay spines for Vets, Doctors, Dentists, Lawyers, Chaplains, Nurses, Nuclear Engineers and SF.
Pilots however will get paid the same as PEdos and Adminers.
Now, I know there are some who will cry, "But you get Retention and Recruitment Pay" Yeah - but quite a few years after you've been recruited and you'll have to be retained quite a few too!
There will be those who cry, "If you don't like it then leave" - pilots are.
I'm not writing this to enter into some sort of 'us and them' p*ssing contest, rather its market forces. The RAF doesn't pay enough - see ya!
On the other hand, the RAF pays handsomely if you want to be an Admin Trainer, HR guru or hotel fitness suite manager.
