Did you read my post on the 92 thread?
PC2 is only permitted in non-hostile environments. If you are operating in a hostile environment you have, post 2010, two options.
1. Your helicopter has PC2e approval - operate to PC2e weights according to the appropriate RFM data. (not sure if all types will have a specific PC2e WAT)
2. Your helicopter does NOT have PC2e approval - You would have to delve into the RFM and find some way of extracting data that will indicate that you can safely fly away from the helideck if you go OEI at or after TDP. It may mean that you are unable to make use of any 'drop-down' and are left with only the 'OEI HOVER' graph to indicate a suitable weight. For most machines this may not even give you enough fuel to get home let alone take any payload. It is likely to be a show-stopper for some.
