I've definitely seen a Powerpoint slide somewhere that shows promotion to Sqn Ldr giving service to 38, Wg Cdr to 44, and Gp Capt to 55.
Haven't the RN been doing this for years - or something similar??
One knows of an RN Cdr who was "binned" under this rule a few years ago - and promptly transferred as a Spec Aircrew Sqn Ldr!!
