Rusty,
Only do an Aero. Engineering degree if you really think you would benefit from it.
They are hard degrees, and if you are not inclined to that 'sort' of study, it is better that you do something you are good at and get a good degree rather than do an Aero degree and get just an average grade.
If you do want to do an Aero. Engineering degree and you don't have a Maths A-level, you could always do a foundation year: I know a number of uni's do them- you just do an extra year of study, the first basically being a 'catch-up' course.
Do bear in mind that all of the people on my course have studied Maths though and we are all finding it difficult now we are in year 2 !!!
Best of luck
Jason
