Thanks Pacificjet,
As i am already a serving member in the RAAF I believe my testing may be slightly different to someone from outside. Basically on the day of your apptitude test you will be required to complete approximately 6 different tests as well as write a 15 minute essay and also complete a Physc interview. The test include a general apptitude test that all personel do regardless of mustering. The other 5 are pilot related tests. including instrument reading, aircraft orientation and maths. I cant recall them all exactly but i hope this helps.
