I'd have to disagree Jim - I've flown plenty of manoeuvres like that in a 412 and airtested a few of them as well - the Nr doesn't droop more than a % or two when you haul in collective.
that's for sure.
These were my thoughts too Crab. I can’t say I’ve been in the position that aircraft was in but I have never really experienced significant NR droop in a 412. Almost all my time is in EP’s so I’m not sure if it’s more of an issue in the earlier models. Quick stops isn’t something we get to play with often but I’ve always found the EP rock solid on power changes.
I can’t pick up any change of rotor speed in the video, well not until he’s just about to hit the ground.
