Back to the original question ... I had the dubious pleasure of sitting OAT's aptitude test a few months ago; not for the airlines but for a commercial helicopter role. I passed all the maths and physics questions, personality test was fine, spatial awareness was fine but I failed the hand-eye-blue-ball-red-line-pedals-joystick test.
I already hold a PPL(H) but I have never played computer games. Somehow, I don't think the aptitude bit is really reflective of someone's ability!
