I would perhaps put the highest qualification you have on there, and allude to 'supporting qualifications'. An aviation CV (we're crossing back to your original topic here!) does not require inventive descriptions of how good you are or have been; it is simply a statement of directly-relevant experience.
Even brand-new baby pilots straight out of school rarely need to mention much about academic qualifications - though they might as well, as they have little else to talk about - unless they are applying for one of the various pay-it-yourself 'sponsorship' schemes. Also, it's worth bearing in mind that many airlines now use application forms rather than CVs, where you may well have an opportunity to note down non-academic quals.
