I'm speaking from the point of view of a Navy flyer who has served on an AAC squadron.
If you want to fly as an officer for more than one tour (2 years) then don't join the AAC. You WILL end up doing a staff job after 2 or 3 years flying and unless you are very lucky, won't touch the sticks and switches again.
If you want to fly jets then join the RAF, if you can stand the uniform and dubious work ethos.
If you want to be a real millitary officer who flies helicopters in varied environments then join the Royal Navy and push for Commando Sea Kings.
The PPL may help in the early stages of flying training but any advantage soon dissipates when going through operational flying training.
