Hey ops normal are you telling me that the part 135 supervision requirements are not command practice? We always logged it as so and the CAA never seemed to mind.
The major difference between the OZ ICUS and the NZ methods is that in NZ the flights must be either an ATO or CTO. None of this private hire ICUS

.
Solowflyers suggestion re the logging of time sounds like the safest option to me, although I would be tempted to just write it in the Command Practice column.
Here is another question... Is NZ Command Practice time recognised as ICUS or Command, or anything at all for that matter, in Australia? I have been assuming that as it is slightly more restrictive surely it could be counted to be at least equivalent to ICUS.
