At the risk of falling out with

, you do
not need physics and maths A-levels to become a pilot. However, if you wish to consider an aero engineering degree, you most certainly will need them.
There is much to recommend an aero engineering degree, but I would only consider it if you are interested in the immense level of detail involved. Many wannabes have attempted this and similar degrees, in the belief that it would help their chances, and found that their motivation was not up to completing a course that didn't really fit their talents. If you lean towards art, history, geography, or whatever, do the course (or A-levels) that interests you and get the best results you can. Failing, or dropping out of, a 'relevant' degree will not help your case. A 2:1 in a less 'relevant' degree will help you! A straw poll of the pilots I fly with suggests that the artists outnumber the scientists by some considerable number.
There was some talk a few months ago of a course at Leeds University which was to combine airline management with some flying. You might try a search on Leeds to see if you can find it.
P.S. Just to confuse the issue, Britannia's latest sponsorship deal requires you to have two of Maths, Physics, Chemistry or Economics at A-level, or one of these at degree level. This is quite common for a sponsored course, although not universal, but has no relevance to direct-entry employment.
