Some definitions say that so long as the Captain doesn't have to intervene I can log as PIC, others say otherwise. Only have 83 hours actual PIC on single engine and Multi engine,
If the Captain has to use anything other than standard calls then you can only log 40% as ICUS, if the PIC raises their hand to point you can only log 30% as ICUS and if the PIC rolls his/her eyes more then four times in a sector less than two hours or more than six times in a sector more than two hours but less than five hours you can log 50% ICUS. I hope that helps?
