Special Jetways?

Fri Jun 25, 1999 2:30 am

Does each airline have a special jetway for some types of their planes? Example, jetway for 727, 737, Fooker 100, and Super 80. jetway for 747, 767, and 777. Or could a 727 use a 747 jetway?

As far as I know, they are universal.

Except for American Eagle's ATR gates in ORD

Several years ago at MIA, I was supposed to fly a USAir 757 to BWI. An MD-80 was substituted. When it pulled into the gate, they had a major problem with the jetway, because it wouldn't go low enough to fit the MD-80. Passengers couldn't deplane and we couldn't board. After about a 30 minute delay, they decided to use steps. They pulled away the jetway and hooked steps up to the forward entry door, and we boarded the plane that way. So in some cases, jetways are made for certain aircraft.

so that explains why there are 'tracks' for the jetway to slide up/down on (only at some gates)

I agree with L011. Also, sometimes it depends on the amount of space at the terminal. For example, at DTW, there is no way that they could fit a 747 at the gates used for DC-9's. Those gates are so crowded together, it's hard to believe they can even park a DC-9. A lot of times at Detroit, 747's and DC-10's are parked exclusively at the ends of terminals for this reason, but when Northwest's widebodies have departed, you will see the gates used by 727's, MD-80's etc.(meaning that the jetways are used for many types of aircraft)

There are basically two sizes of gate parking bays: one for smaller planes (up to 767-ish) and wider-spaced ones for 747s, L1011s, DC10s, 777s, A330/340s to accomodate the wingspan (although obviously smaller a/c can also park here). On the tarmc are painted marks, with a/c types next to them. This is where the nosewheel should stop for door L1 on that particular type to be level with the jetway. That's how the marshall knows when to bring his wands together and tell the captain to stop. Then the jetway aligns vertically with the height of the sill.

I think the 777 needs a larger opening than say a 767. The way Boeing designed the door makes it swing way out and if your jet bridge isn't log enough...

I think the door size of the jetway is standard. But whether it can be raised or lowered; or how far it can telescope, depends on the surrounding space of gate. Certain gates are spaced closely to only handle smaller planes. And I think the airport might choose not to equip the jetways of these gates with the hydrolic equipment for raising or lowering it. That's why you have the problem when a MD-80 is parked at a gate for a 757.

In Delta terminal at LGA, widebodies (767, L-1011) have to park at the inner most gates so that their long bodies don't extend all the way into the narrow taxi way and block other planes. The jetways on these gates can accomodate both MD-88 and L-1011. But the gates on the outer side of the terminal only needs to handle 727 or MD-88. So the jetways there can have less equipment on them.
