Depends what you're applying for and what your flying history is?
Not sure about PICUS, but P1S can be counted as PIC in certain circumstances. In our operation we log P1S from the RHS when its our flying sector. This can go towards P1 time required for the issuance of an ATPL.
If however you are asking from the perspective of a first commercial job, Mad Jock is prob correct in his statement. I think P1S (as mentioned above) only applies in a 2 crew JAR 25 operation.
