Eastern Skyjets,
With the exception of neville nobody and one other, most of what you have been told here is garbage, and not even a good grade of garbage.
Under ICAO Annex 1, it is AICUS by whatever name.
You need to check the rules for your country of license. Don't just ask somebody in the company, check the local law, get your facts straight. You might ask another Australia who doesn't know either , so just makes it up.
What it is NOT, is in command. If your logbook does not have an AICUS/P1-U/S column, it is logged in the command column, with the name of the Captain of the aircraft in the pilot column to make it clear you were not the pilot in command.
Do your own homework, find out the local air law on the subject, and take no notice of people who, quite simply, do not know what they are talking about.
As for all you anal retentives in Australia on this subject, who can't tell the difference between P1 and P1 U/S, with Australia's non-compliance with ICAO, don't forget, Qantas F/0s log AICUS (NOT co-pilot) on every sector where they are pilot flying. And have done for many, many years. And it is legal.
Tootle pip!!
