I have around 3,000 TT, about 100 - 150 ICUS, mainly from my first > 5,7 command, & also to fulfill insurance reqmts when I started out in PNG. Just seemed a little silly to list such a small amount of time separately.
I list my total time, and then my actual COMMAND time. ICUS doesn't get listed on my resume as I see it as irrelevant. You may as well list your dual hours as well.
For the purposes of stating how much command you have, leave ICUS out of it.
ICUS is good for 2 things - getting time on type required to operate as command, and getting trained/checked to line at a new company. That's it. Ohh and you can also log your CIR renewals as ICUS if you want as well.
You can also base it off the organisation you're applying for. If you know that the requirements under CAO 82.3 for instance are important for them, and you won't be hired without meeting them, then tailor how you report your experience that way. (ie for 82.3 ICUS time is included when measuring command time
If you are a Kiwi, you would probably log that alternate sector you were hand flying on a normal day as Command time - even though the Captain wasn't even aware you were calling it ICUS.... (and the Chief Pilot only picked it up from a logbook check.... )
