S76 optimum Nr speed
Hey Nick,
Just back from another stint at FSI. Topic of discussion during one of the sim sessions was Nr speed for best performance.
As we were told at FSI, the S76A was having problems with Cat A certification when the Nr was maintained at 100%. It is said that to meet the required climb figures the Nr was reduced to 99%, 98%, 97% and finally to 96% at which RPM the aircraft met the requirements.
No furthur testing was required or done.
During my S76 carreer 96% Nr was sold as the most efficient Nr speed for climbout in an OEI situation up to BROC. If you were at 94% for instance you were not flying the aircraft in its optimum configuration with regards to Nr speed.
Is this a fact. Did you ever experiment with lower Nr speeds to try and gain rates of climb or to lower rates of decent?
Cheers
