Keep the NR at 100% (324rpm)
kulttt,
I will try to find the report. It is in my archives somewhere. The problem is with the lower NR at high cruise speed, high gross weight, and high density altitude. The collective pitch is high because of these conditions. The rotor rpm decay rate is rapid with a throttle chop/engine failure and keeping the load factor above 0.5g is next to impossible.
I'm on my way to HAI and will not return for several days. I'll look this up when I get back.
