Geoffersincornwall what I just wanted to make clear is something that YOU seem not to understand and that is the certification frame, i.e. what is legal in accordance with the RFM and what is not.
As JimL clearly explained, operations can (some times) relieve fro the RFM limitations and this what actually allowed offshore operations (otherwise not possible with helicopters with more than 9 passenger seats), none the less this does not mean that these operations are not violating the RFM limitations.
These operations can only be carried out (not in PC1 or PC2e) accepting some risks that come from the exposure time (PC2 with exposure).
