I don't know why there is so much negativity about ICUS. Sure if you only have ICUS in you log book it can look a bit crap, but for the most part you can't avoid it.
You have to 10 on type (legally speaking), but then you have the insurance requirement which varies operator to operator (depending on how much/little they want to fork out on premiums). I have had to do in excess of 50 hours ICUS on type (for smaller GA twins, ie not above 5700kg) just to meet the insurance requirement. Sure I didn't get paid on ICUS, but at least I wasn't paying it myself!
So why should people think it looks bad that I have a couple of hundred hours ICUS through my logbook just because I logged it legally and not as Command?!
