How does the EC 145 show exceedances?

I am new to the 145 and understand that a flight report will show a mast moment exceedance, or mast over torque. How then would you check an engine over torque or and OEI over torque? The best that i...

That makes lot of sense as to why an engine would get hot without exceeding Ng limits. Because the compressor might be in the backside of its optimum efficiency at a high power setting.

Obviously as in your wonderful example Ng and TOT are not linear as those ratios would be approximately 1:9, 1:12.5, and 1:10.5 but fuel flow and Ng would be wouldn’t they? I believe SLFMS is correct...

High TOT in flight EP’s

How would lowering the collective (that is, reducing power) help to cool the engine? I
understand that it is less fuel, but less fuel means a lower Ng, so less air coming in since the compressor is...

Wonderful! Thank you so much for that information and the location on it!!! That explains why you have to reduce throttle quite a bit before you get an RPM droop. Thank you again!!

That was my exact thought too LRP. Unless you killed the battery and gen under 85%np the FADEC should not lose power.
