You need relatively calm conditions of course. Not an issue if you have taken the time to actually read the AFCS FOBN.
What about the collective being engaged as a protection at 60kts?

VR is a great training tool for some things but it would suffer from the same issues - accurately reproducing handling qualities in hazardous scenarios.
yes, I agree.. in the fixed wing sims its the exact same issue… the FM at the outer edges of the envelope are not always like in real life!
I dont know how many times I have sat in a Level-D sim thinking that the damn thing does not fly like the real thing. My point is that its better than nothing as its akin to not teaching spin recovery to PPL students except have a quick chat about it. Same here. VR and modern tech has its advantages in certain training exercises in the same way you have to teach upset recovery in a real airplane as being upside down in real life is more unsettling than in a sim, but again doing all this in a Citabria is a whole lot easier than a 737also, so somewhat limited use also.

Info is direct from Airbus Flight Operations Briefing Notice (FOBN)12-22 applicable to Software Step 3 K10_15274G_123 and personal experience.
Vortex ring protection is only applicable with a vertical axis engaged which does not occur with selection of GTC-H from forward flight unless you add a vertical mode manually.
