So simply make it AC, LAC and SAC as the rank without is being shorthand for anything, meaning SAC is an SAC and the term Senior Air Craftsman wording no longer exists, hence no sex discrimination problems.
I was shopping in Tesco and saw a female naval rating in the store. She was badged as a Leading Seaman and it occurred to me that in days of the WRNS she would have been a Leading Wren. I asked her what the modern term was and she told me she was a Leading Hand ( as were her male counterparts ) which seemed to me to be an eminently sensible solution to the problem.
By the way, Nutloose, it's Senior Aircraftman (sans 's'), as I'm sure you knew
