Flyingwrench-the reason you are being ignored is because you have no idea what you are talking about. This has got ZERO to do with 121/135. The question relates to the priviledges of a CPL vs ATP. Those reg's (P61) make no reference to 5.7 tons or in fact any other weight restriction. The consideration is whether the aircraft is CERTIFIED for single pilot operation, not if the TYPE of operation requires 2 crew.
So here's a question for you then, by the same scratchy logic does a Caravan require an ATP driver? Most are operated under IFR, and in most cases require 2 crew? How about a King Air 200?
