The only difference is the anthrometric assessment. RAF select almost exclusively for fast jet and therefore an individual must be in proportion for that type, otherwise limbs get lost in ejection. Rotary and Multi-Engine are more anthrometric forgiving. I was borderline rotary for my knee to backside measurement and at the time, early 90's, was only suitable for Buccaneer in the fast jet world.
The AAC now also look at weight very carefully. Too light and the Apache 'stroking seat' will not activate, too heavy and you go through the floor, either way sustaining injury.
However, for the sickly child type issues the 3 services are in line.
