...unless you are are taking off and landing offshore to a floating runway long enough and wide enough to simulate PC1 onshore you are then left with a situation of being PC 2 or PC 2 with exposure or PC 2 enhanced, I.e. you do not have full OEI accountability offshore (bring your own floating runway sufficient to cope with an OEI situation at the weight and temperature corresponding to your respective CAT A chart from your respective RFM)
What about the scenerio where a CAT A/PC1 helipad procedure are published?
Even a HV diagram with no "avoid area" at the operating weight?
The Q seemed to be was it possible/legal, not whether people think it's prudent.
