Here in EUG, we have fairly new "contraptions" called dockloaders that we use for our CRJ-700s and Dash-8 Q400s. They're similar to a jetbridge only in the idea, however they are stationary. There is a platform that raises and lowers depending on the height of the cabin floor, and then an "end ramp" that moves left or right, to line up with the doorway, and then rotates down into the doorway. It also has an inflatable canopy that will inflate down to the aircraft, making a seal with the skin of the aircraft, keeping all the passengers out of the rain. Its not too bad, as long as the captain is paying attention to you as you're marshalling the aircraft in...there is VERY little room for error.
I do have to say that last time i flew home, on my return i flew from CID
on a NW
Saab 340, the "jetbridge" in MSP
, which reminded me of what we have in EUG, was very nice.
As a footnote, if I recall correctly, QX
Dash-8 Q200s use a jetbridge in YLW and I thought somewhere else...can anyone help with that?
