To clarify, there is no 'bristol gs scholarship'. The courses were donated to the PPRuNe fund, the boys at PPRuNE decide what to do with them.
Generally 'discounted' courses are not considered scholarships, they are rarely as good a deal as they first appear and they often turn out not to be discounted at all. A scholarship usually involves some third party paying the fees. I believe GAPAN do a PPL scholarship, for instance, and the RAF certainly used to run flying scholarships up to first solo, I'm not sure if they still do. To my knowledge there are no scholarships, in the normal sense of the word, available for the ATPL
