Humberprop
Have you got any previous experience? i.e are you an ex-mil controller? If so then you will be able to cut down the basic course to 4 weeks. If not than as previous posters have said you will need the 6 weeks as the study load is high. As for the ADI well that will depend on the number of people on your course. If the college can get it done quicker then you may be in luck, however that might not make it any cheeper
Costings, set aside £20k at least.
