We can arrange a visitors pass for you for 1-5 days but because you are under 16 we require to have the pass countersigned by the BAA Ops Duty Manager - which isn't really a problem!
We have rarely taken work experience students because there is very little for you to do - as has already been mentioned you can't speak to the aircraft on the RT for example!
Unfortunately I'm not in a position to approve your work experience but I can at the very least arrange a visit to the Tower at Gatwick for you if you do get turned down!
