Jetbridges Without Wheels (Fixed To The Ground)

Sun Jan 22, 2006 3:08 pm

The recent thread about dual jetbridges got me thinking about other kinds of jetbridges.

I recently realized how some jetbridges in some airports are actually fixed to the ground and can't move around much.

I was wondering, what exactly is the usefulness of these jetbridges?

I used to travel through AMS a lot when I was younger, and I know they are quite revolutionary with the dual jetbridges for the 747 with one of the jetbridges going over the wing to dock at one of the back doors. While browsing some pictures, a few jetbridges caught my attention as they appear to be fixed.

I am not entirely sure, but I believe this middle gate where a KLM MD-11 is parked is equipped with a fixed jetbridge:

Also, I'm not entirely sure about these, either they don't have wheels or the wheels are hidden:

Perhaps some Dutch members can clarify, it's been 6 years since I passed through AMS.

All of the jetbridges in CAI's Terminal 2 are fixed jetbridges, however they are also pretty old:

The first reply by TUNisia in this thread has photo of a Swiss A340-300 docked onto a jetbridge in Terminal 2, you can clearly see how it is fixed:
http://www.airliners.net/discussions...general_aviation/read.main/2554841

In BEY, 10 of the 21 gates are equipped with fixed jetbridges, however it is only the gates that are between the two wings of the airport.

Here are two photos of mine and you can clearly see how the jetbridges are fixed to the ground:

http://img.photobucket.com/albums/v168/mea707/beyamm/100_0085.jpg

In the case of BEY, I get the impression that fixed jetbridges are used in the areas that are more tight since they are only put on the gates between the two airport wings, while the gates on the outside of the wings are equipped with normal jetways. Take a look at this map to see what I mean:
http://mea707.lrehosting.com/mapbig.jpg

Would it be accurate to say that the advantage of fixed jetbridges is compactness? For the smaller fixed jetbridges I mean...

What other airports in the world are equipped with fixed jetbridges? I believe they are also called pedestal jetbridges.

Any feedback would be greatly appreciated.

There are 3 left in Columbus, all on the B Concourse. When the B Concourse was the ONLY concourse at CMH, all the jetways were fixed to the ground. Since that time, most have been replaced, however 3 of the original jetways remain, two of which are unleased, and one which belongs to United.

The two that are currently unleased used to belong to America West. I remember bringing a plane in to those gates; you had to get the nose right on the mark since, as fixed jetways, there's very little room for error. If you stop the aircraft too far forward, you can forget about opening the main cabin door.

In a widebody only situation, there is really not much reason to need to move them. You can lift and extend without needing to move them. As long as you have the space to park the jet in the right spot, it shouldn't matter.

America West uses an old semi-fixed jetway at Gate 4 at Oakland International Airport. The boarding platform can slide back and forth on a sort of rail system, but cannot move up or down or laterally. When the Mesa CR9s use the gate, pax have to deplane to the tarmac, walk through the HP ops area and use a back set of stairs to enter the terminal.

ORD terminal 3 L concourse L2,L4,L6 has fixed jet bridges. They use to be leased to Apple Vacations. A A320, B737, B757, B727 use to use them. Only difference was where the particular aircraft nose wheel would stop. When the correct aircraft stopped on the correct pavement marking, the forward door was always perfectly lined up. All you had to do was adjust the height and extend the tunnel to the correct length.

that was my point. as long as you have sufficient room behind the jet so it can pull in to accomodate the correct wheel placement, there really is no need to roll the jetway.

One can also assume there is less chance of damaging the plane if the jetway has less ability to move. The more options you give a driver for movement, the more opportunity you present to screw something up.

the benefits of having a movable jetway are of course more flexibility in getting every jet as far out of the alley as possible, and also to get the jetway further out of the way of the ground ops when not in use. But it really isn't necessary in a place like LHR or NRT on widebody gates.

This jetbridge and the ones in the other picture have wheels under the shrouds. They have fixed wheels that allow them to only move left and right. If you look closely, you can see the black tire scuff marks.

I use to work in MCI and they had fixed bridges. If you missed the park line for said aircraft you had to push the plane onto the line, making for delays.

BA,

Indeed the bridge on th KLM MD11 is a fixed bridge which is only able to extend but not to move left or right.

As other poeple already mentioned all other bridges have their wheels underneath the shrouds.

LGW still has a couple of fixed ones on the South Terminal domestic pier, the one I used with Jet2 still has a BAC 1-11 boarding ramp on it! The bridge has a telescopic end which meets the aircraft. MAN also has a similar one at T1 which can be seen from the large windows airside.

DCA has some in Terminal A, which is the older terminal. If there's not much room to work with, that's the main usefulness of them. They extend forward (towards the plane) and move up and down as needed, but most there are actually part of the terminal structure.

At ARN all the bridges are fixed, except on the latest pier F.
You must be able to stop the aircraft accurately and we use laser guided guidance devices, and the aircraft usually stops on the line. One advantage is that it is a doddle to operate the bridge, and it moves onto the aircraft very quickly.

Interesting, so you are saying this jetbridge at OAK cannot go up or down, and only forward and backward? That's got to be a pain.

In my experience, fixed jetbridges can move up or down as well, this is at least my experience in BEY.

Quoting Tristarsteve (Reply 14):

What exactly is this laser guidance system called? They are like traffic lights for the aircraft and they tell the pilot if they have to turn to the right or to the left, am I correct? I've seen them in many airports.

Interesting, I never really thought of that.

This makes sense. In the gates with fixed jetbridges in BEY, the aircraft move extremely close to the terminal.

You can see the difference from these two shots:

My guess is they opted to put fixed jetbridges in the interior gates of the terminal so that aircraft are forced to park as close to the terminal as possible to keep the tarmac between the two airport wings (piers, concourses, whatever you want to call them) as free as possible to allow as much maneuverability as possible when backing a plane out.

I know that DAL,HOU,OAK,PHL,and MSY all have a few Jetways that do not move horizontally. I have wondered myself as to their efficiency. I happened to see a NW 744 that diverted in PHL have to be pushed back a few feet after they missed the stop mark at gate E6.

Quoting Chris133 (Reply 18):

The B747 has about the biggest door and it opens outwards so you need a wide jetway to get it in. The best aircraft for fixed jetways are Tristar and B767 which have inward opening doors so there is a lot of fwd/back error allowed.

Quoting BA (Reply 16):
What exactly is this laser guidance system called?

Ours are called AGNIS (aircraft Guidance nose in system?) The operator sets the type of aircraft, then the laser measures the nose of the approaching aircraft and if it is correct a series of bars light up which extinguish as the aircraft nears the gate. There is left/right guidance as well. Works very well. An aircraft needs pushing back about 1 in 500, usually a pilot taxying too fast. Can be expensive if you hit the jetway?
Once I saw an operator enter B747-200 and then a B747SP taxied in. It never got to the stop sign because the jetway was embedded in the leading edge of the wing! Air China at ARN many years ago. The two types have the same nose profile.

In Lisbon (LIS) there are (still) airbridges without wheels...
In fact, 'my aircraft' have been pushed back a couple of times. Very inconvenient. I have been told the bridges are an old (and cheap) model.
There are marks on the ground for where different types of aircraft must 'place exactly' their forward landing gear wheels...

I know MSP has a few fixed jetways, PHX there are fixed jetways...I think the fixed jetways are cool looking however the fixed jetways in PHX (T-4) if it's raining it will get wet inside the jetway.

There are quite a few fixed jetways in SFO especially some in gates 20-36 and quite a few in the UA terminal.

DL in SLC has quite a few fixed jetways.

IAD has 2 or 3 fixed jetways in concourse D.

At BIL, I have noticed that the different airlines each have a different type of jetbridge. The NWA one is like the ones you talk about. The main part is fixed, but the part that connects to the plane moves back and forth.

Quoting Jetdeltamsy (Reply 24):

$ At the time of installation if the lease holder of the gate used similar sized airframes then only simple jet bridges were required saving the cost of motors wheels, controls, Mx costs etc.

I would not think it would be frugal these days with constant shift in airframes to meet passenger loads to use a fixed bridge very often as more flexibility between airframes would be in order. That route from DFW that had a 67 on it last year may have a rear loading ATR next year.

IAH has all three types. The fixed jetway where it is imperative to stop the nose gear on the proper mark. The semi-mobile where the jetway swings back and forth on a prescribed arc. We also have the fully mobile up and down drive it around type.

Some gates at Terminal 2 at YYZ are still fixed bridges. All of old T1 were fixed as well.

The T1 bridges used an interesting system. They were equipped with an adjustable feeler - like a horizontal flexible whip antenna. They were set for the appropriate aircraft type, so that the pilot just had to stop the plane with the feeler touching the front post of the windshield to be correctly positioned.
T2 may have had the same system, but you could only watch from the T1 parking garage.

Currently in WAW there are 2 operational jetbridges. There used to be 8 of them, but the terminal expansion will see more modern glass'n'metal with wheels.

Back to the subject, they are fixed and do their job well. They only extend back and forth and go up and down. Of course if the aircraft stops at the right position.
