You are entitled to your views Xred, but the issue is quite relevant to lots of airlines being somewhat behind the times.
A thorough understanding of a PC12, with its EFIS and other modern equipment is far more relevant to an airline pilot's experience than hours in a 35 year old Navajo/401.
Face it, the only time that the multi experience is relevant is in the case of an engine failure, and how many of us have had one for real?
