Hey Mate
It involves a personality test first off . Only around 5 questions just answer what you think it right ( cant fail this part ) . The sim test ..... Its like playing flight sim but with no control over the aircraft . You will be flying over various land marks and doing certain turns . At the same time you will be playing an arcade style game , flying a plane around boxes and at the same time you will also be answering simple cognitive questions . So while playing the game an answering the questions you will have to look out the cockpit window and spot aircraft in the distance memorize landmark under your turning points . You will also hear ATC . Remember as much as you can what they say during the flight . There will be questions on this after the flight along with questions on your route , the aircraft you spot the cockpit layout etc . Once all this is done you will do the exact same test again to test how much you improve over the first time .
This should help heaps , you can't really study for this test but at least you know what your getting into .
