Simply said PC-1 might be understood as OEI HOGE performance at a defined Gross Weight
Simply said that's rubbish!
EASA define PC1 as "‘Operation in performance class 1’ means an operation that, in the event of failure of the critical engine, the helicopter is able to land within the rejected take-off distance available or safely continue the flight to an appropriate landing area, depending on when the failure occurs."
In order to comply with "safely continue...." there are further implications for OEI performance i.e. climb to 1000 feet, or MSA.
It has nothing to do with OEI hover performance!
Why do we seem to have a continuous stream of
uniformed drivel from AW009 and turboshafts of late?
