A lot of experienced ppl's are put off by the time and financial commitment required to attain a CPL or even CPL/ATPL exams. Many are also limited by medical requirements. I believe however that the EASA proposals will relax the class 1 medical aspect. To what extent though I dont know. I also think that the type of ppl who will be inclined to do the rating, will be the one who does it for the love of flying and wants to put something back into viation. I dont think the pay will be a huge issue for them. The cpl 'hour builders' so to speak will also still exist. They will teach on their cpl's, and disappear off when the first airline job comes up. same old same old...!
