I know I keep wittering on about training/experience, but I found the following quote on a website to be quite significant:
" In flight the MetroLiner was pitch heavy, roll dampened, and rudder sensitive. In addition control pressures changed with airspeed, thus you never really had the feel for the plane until you had around 100hrs flying it."
Not the place for a two week F/O in ?? visibility, at half of the legal DH with a captain who was possibly more preoccupied with visual cues than monitoring airspeed.
