I flew the Fokker F-50 (came after the F-27 or Fairchild FH-227) 4,5 years
and made the transition to the Dash 8 Q400. 2 very good things: The powerful engines and glass cockpit. Very economic airplane for the airlines. But designed and produced very cheap. The Fokker was simply a quality product (that killed Fokker). The oldest one I flew was from 1989 and still quiet with very little vibration (actually none compared to the Dash).
I flew a Q400 just 2 years old. It vibrated (so some people might have liked it), noisy (the QUIET one?) numerous
issue's, autopilot would always disengage at the worst moment. Hmmm....
But apparently Horizon masters the operation of this airplane.
I saw the Q400 as a nice transition to a jet.The Fokker was comfortable, reliable and VERY easy to fly....but slow.
If you are starting just go for it because if you can fly the Dash....(you will learn why they call it Trash) you will make easy transitions to any airplane.
The toilet is a joke. Did anyone had a stuck passenger?
