Hello! At the risk of flogging what is clearly a dead horse by now, I was wanting to know about the mechanical comp. tests at the AIB. I passed my RT mech. comp. though I have a feeling it was maybe a bit hit and miss, and so my AFCO said to go and buy a GCSE physics book and get cracking, which I have duly done, in preparation for the AIB. However having never studied physics and not being the most mechanically minded of people, there seem to be an awful lot of equations and maths in it all. What I want to know is, do you really need to learn all the euqation type stuff? I am concentating on electrical circuits, gears, motion, speed etc. but judging from my RT, you neither have time to use complex formulas nor do you need to. I was just wondering what the general consensus was as I am sure the AIB tests are going to be a wee bit more difficult than the RTs. I have looked at the RAF practice questions, the fireman test etc. various books and sites that have already been recommended on here. My apologies if this has been covered somewhere already, but I couldnt find it! Also at something of a tangent, but I haven't been asked to do any running on a tredmill yet!? I had my medical and all my forms have been sent off, I haven't quite passed the medical yet due to some very mild eczima, but my AFCO doesnt see that being a real problem. Will this test be after the medical then? Just don't want to be missing out on all the fun Well thanks anyone who contributes to this, I have been following a lot of the threads for the last few months during the recruitment process and its great there is so much help here. Nick.
