Spusa,
Things may have changed these days but from my own career path I'd say it's not too unusual for an RAF helicopter pilot to become a Qualified Helicopter Instructor (QHI) after completing his/her first operational tour.
The QHI course is a formal course run by Central Flying School (Helicopters).
I was posted to CFS(H) to have my brain removed (as RAF folk say) after my first RAF tour finished in 1983.
