Thank you very much..:) Do you know if at 55...

Thank you very much..:)
Do you know if at 55 kCAS, still at high density, the NR drops down to 100% and how it decreases to 96.5% increasing the speed?

hover RPM

Hi folks,:O
I have a question for 145 pilots:
At high density, during hover, in the NORM mode operation, I guess the rotor speed is between 101% and 103.5%..is it 102% like the 139 or slighly...
