a little more detailed
Thank you all for your anwers!
I have to be more clear about the situation we had:
-carb heat wasn't applied (down)
-it was a cut grass surface
-we had already hovered 2min before we lost rpm
-the power we applied (when rpm dropped): 23 inches Manifold Pressure
-the rpm dropped very abrupt (lower than 97% in less than a 1sec)
-when the rpm dropped we had already stopped the turn
-weight was within limit with the RFM
-RFM says it's possible to hover IGE up to 10000ft (PA) with the weight we had
An other question:
-When full power is used (butterfly at approx. 45° open) what about the possibilty to risk carb icing?
Greetings.
