I was hoping that someone, who actully knows something about aviation medicine, was going to answer your question, as to whether your brother who is a diabetic, can get a PPL. As no such person has replied - here goes!. .A few years ago, at my local flying school, as far as I recall, a student with well controlled diabetis (spelling?) was allowed a restricted medical certificate. All his "solo" training flights, had to have an instructor in the right hand seat, who was not allowed to speak or touch any of the controls. Once he had got his PPL, he had to have someone in the right hand seat, who held at least a current PPL, to act as a safety pilot.. .I would suggest that you contact your local AME or the CAA Medical Section at Gatwick, to find out what the current situation is.. .Also there is the new propsed UK National PPL (NPPL), that should be in place within the next 12 months. NPPL holders will be restricted to light, simple, S/E aircraft, in daylight, VFR within UK airspace. The medical requirments are likely to be, just an examaination by the student's own GP, & be up to the standards required for an (HGV?) driving licence, only. This may be of help to those who cannot meet the JAA Class 2 medical standards. The latest draft of the NPPL reglations, should be somewhere on the CAA website.. .Good Luck & Good Flying to you & your brother <img src="smile.gif" border="0">
