Category of ops and performance classification
Dear Rotorheads,
Do ICAO or EASA or FAA have the same definitions for classifying Helicopter performance and the type of operations which a machine can perform or it varies with the type of regulations in force. Kindly advise
Happy touchdowns

EASA have a code of performance which is fully compliant with ICAO.
The FAA does not have a code of performance but, through application with the limitations of the RFM - i.e. the HV Diagram is a limitation, has a pseudo Performance Classes for helicopters which are certificated in FAR 29 and have more than 10 seats. Helicopters that have a certificated mass of more than 20,000lbs (and 10 seats) should apply the Category A procedures (PC1); those with a certificated mass of 20,000lbs, or less, (and ten seats) should apply the Category A second segment climb performance.
Alleviation from the HV Diagram is permitted under circumstances that are described in FAR 91.9(d).
