TGP, aka pilot camera - it's standart aircraft function since jets dlcs.
First of all, try it on another planes, like standart A10D. Default combination is LCtrl + Right Mouse click.

If it isn't work with A10D, it isn't mod problem.
Double check Options->Controls->Common -> Targeting Camera binding.

at the end it was a pretty dumb problem. Since I'm from South America, there was a misstranslation, so instead of "targeting camera," it said something else that wasnt really related. so i wasnt able to find the action and configure the keyboard properly. but at the end the answer was right in front of my eyes. Anyway, thank you very much
