Q Codes;a definitive list
Q codes are great for winding up crusty ol' skippers...nothing riles them up more when the copilot knows more Q codes than they do. All in fun, of course, but now it seems my supply is running dry...QFU was perhaps my finest moment (magnetic orientation of runway in use...best used when setting up the APFDS, stating forexample "QFU is 262", then expressing surprise when the old boy looks unsure as to what you are talking about)...
So please, more Q codes, the more antiquated and rare the better...lets seee if we can compile the definitive list.
Yours subversively, Waldo.
