Trying to get up a discussion subject for a CRM course - if you were having to nurse a helicopter back on low fuel, are you better off reducing power and beeping the rotor RPM down to the bottom of the green range or pulling as much power as you can, on the basis that the (turbine) engine's best power is in the high range anyway and that you get a higher percentage of groundspeed against airspeed?
Answers on a postcard please.....
