Sorry AB, think I may gave been unintentionally obtuse!
The only real point I was trying to make was that unless one is a captain one cannot log P1 in the 'Holders Operating Capacity',
it has to be either P1u/s or P2 and that my interpretation of GID44 is that this will be the case regardless of licence held.
If an F/O is given a sector he may prefer to log it in the 'Holders Operating Capacity' column as P1u/s rather than his only alternative, P2, even if he does have an ATPL.
