CTC do 3 hours of proper UPRT in a Slingsby. There is unusual attitude stuff on the CPL/IR syllabus as per legislative requirement but it's very basic. Eyes open, oooohh 30 degrees nose down, 20 degree bank, power off bank level pull up. It's not very extensive. MPL's do UPRT in the sim.
I'd like to see EASA require a mandatory 10 hours of real aircraft UPRT, plus two hours of unusual attitudes at night recovering with reference to instruments like the IR test.
Also I don't think it would hurt to teach g management techniques like straining your core muscles and breathing out. Would certainly help at the end of the UPRT lesson if your instructor asks if you want to do a few quick aeros on the way back home
