ICUS
3rd Axis,
I had a similar problem, especially if it is a day/night split. I rang CASA a queried it. How do you log it?
From CASA, although beware there probably differing opinions even within, but....
Fortunately I only had one ICUS flight, but anyway, I have logged my time in the command column, though having said that, I have not totalled it at the bottom but rather drawn in an extra box underneath. This to be honest has been a real pain. I think about it now but depending on your circumstance if you are doing lots of ICUS, I'd recommend just getting the Theory Centre type logbook which has the ICUS columns. Just to prevent all the dramas.
Hope this helps.
