The complete list of Q codes can be found in a publication called "Reglement general et additionel des radiotelecommunications," part of the Convention on International Telecommunications and published by ITU in Berne (CH) in 1938
The Aviation odes are only the series QA to QD and QF to QN, (rest is for railways, Navy and radio amateurs, etc .)
I do not have a scanner, but if someone is really interested, for a study or something else, e-mail me an adress and I could send you a photocopy of the list I have.
