Seems like engine fire and ILS approaches would be pretty hard to do if you've never flown a 737 before. Are they looking for a general understanding, ability to fly and decision making? You wouldn't know what callouts ryan uses or anything, so I'm finding it hard to understand what would be considered good enough to pass if they expect you to fly to airline standards.
Callouts, flap and powersettings, are you supposed to fly as PF only or PNF as well?
