I'll be a contrarian - apply - it costs nothing. You may get in, you may not. 30 years ago I started a selection process with 1200 other applicants. Nine passed - including me. A statistician would have told me not to bother.
If you want it badly enough you stand a strong chance of getting it. If it just a holding position for something else you want more, then you probably won't get it. Good luck.
If it's not a silly question, why are you not applying as aircrew?
