ICUS? So you call up an operator at Lake Eyre after the last guy quit abruptly, trying to secure an Airvan job and have no time on type. Do you think they are going to give you 5 hours ICUS whilst you find your feet? No.
Any operator with a shred of professionalism should. Every job I've had had anywhere from about 5 to 20 hours ICUS (depending on aircraft) before being let loose.
