FfF, actually I don't see a problem with a prospective pilot asking about potential salaries. I think too much is made of the idea that flying is a vocation. It may be a profession that relies on enthusiasm for the machinery and the 'glamour'
rather than pay to attract new entrants, but it still has to put a roof over our heads! Asking about what pay one's likely to get is perfectly reasonable for someone considering flying as more than a romantic dream!
