Nobody's disputing the value of ICUS, we're banging our heads against the wall with people paying for it.
There's more than a few operators around who do ICUS for FREE. In fact you actually get PAID to do ICUS. You start working for the company and immediately receive a salary, when there's a bit of movement in the company, they pay for your endorsement on the next largest aircraft in the fleet and send you off flying with a more experienced pilot until you are competent.
If you want to get real fancy some of them even work for CAR 217 organisations where the pilot sitting in the right hand seat has been checked as a Supervisory Captain rather than someone who just happened to do the endorsement three months before you and still learning themselves.
Once upon a time airline pilot's didn't pay for type endorsements either. In fact there's still some companies where this is the case. Think about it.
