Cool. An actual limit.
I can “do” actual limits. I can even agree that “bad things” might happen above the limit.
So it’ll actually turn above 2500 RPM when WOT below 5000’ in level flight? Or are you more concerned about busting the limit in a descent?
Obviously they’re such dogs up here as
@flyingron mentioned, that there’s little chance of one over-revving on anything but the coldest days of the year.
To match up with Ron’s story, the RPM would have had to have been approaching or exceeding the limit for the instructor to ask to reduce power as it sped up in cruise, I assume.
THAT I can see happening if they’ll overspeed in stock configuration (no climb prop, etc) below 5000’ in level flight.
