I had never heard of this 2 bar thing at all until I started reading this website. You're either a captain or an F/O. Of course where I live you likely won't even be getting a sniff of a airliner till you have at LEAST 3500-4000hrs and that is a bare minimum!! At the last place I flew the minimums for an F/O on a BE-10 was 1500hrs. Captains needed 3000hrs PIC to qualify. I guess with the lower minimums it makes sense to limit what the F/O's are able to do.
