"and doesn't even know what FMS stands for"
Who cares? It ain't no thing. I had to learn it coming from the 727 to the 757 and, you know what, I'm dang glad I got to fly a real jet before one with an FMS. The FMS is no big thing, and you gotta go if it's broke.
The more experience guys have before entering this industry the better. All I know is 300 hours doesn't cut it....period.
