In my opinion, anyone who feels a need to practice the pilapt tests in order to pass them is a charlatan. The whole point of the tests is to give a fair, unbiased reflection of someones aptitude for flying, taking into account the fact that it is the first time that someone has done it. If you practice before hand what do you achieve?
1. You deceive urself as to whether you are cut out for flying, which could have serious consequences if you realise you are no good at it when u come to for example ur IR (which I believe if the most difficult part of the training, although not done it yet), after having spent a load of cash thus far.
2. You deceive and cheat which ever training organisation you are trying to get into. CTC will not be happy when they realise they have been taking in a load of wannabes who are not as good as they would want them to be, due to them gaining a place un fairly through practicing the pilapt tests before hand.
3. You are also cheating innocent wannabes out of a place which they deserve more than you. Say for example that you practice like mad, and beat a guy who is doing the tests for the first time by 1%, who has the most aptitude for flying? Who deserves the place on the course more?
As a final word, ive gotta say that in my honest opinion any one who does fail the tests really should take the fail seriously. I took the ones at Cranfield (with no previous practice of course) and destroyed em all, dispite being knackered. They are easy man! If you cant pass them then you are not cut out to be a pilot, simple as that.
