747 Two Level Boarding?

Fri Aug 06, 2004 9:21 pm

As airports start to modify gates in order to keep up with the A380, once those are finished, will it be possible to board the 747-3/400 from the upper deck door? It will certainly reduce turnaround times and thus costs.

Regards,
Matias.

It doesn't seem very efficient since the upstairs doors are not very large and not many people sit there. Also, when you come down the stairs, you are in the "lobby" anyway.

What they will probably do is use two main deck doors, as they do today in many places..

The Upper Deck doors cannot be used for boarding, as the evacuation slide is in the way. I will try to find some photos.

In that picture, you can see how the evacuation slide is in the way.

Have a look at this pic.

You can clearly see that the door opens upwards, and the slide pack is in the way so no chance of boarding through the U/D door as you couldn't open the door with a jet bridge attatched.

Just for info, I raised one of the new A380 bridges up to it's maximum height just after they got installed in T3 to see how high it went. It was quite amusing to see the look on the Capt's face as he taxiied past and I was at the same level as he was.  Laugh out loud

So will the A380 be able to be boarded from the upper-deck? It would seem like it would take a long time to board all 200 odd pax upstairs if It couldn't.

Yes.

Not necessarily. The first two pairs of doors are intended for single-level boarding of both decks: Passengers for the upper deck will board through the front door and climb the broad staircase to the upper deck; Passengers for the main deck will enter through the second door.

Dual-level-boarding will spare the passengers the stairs; That´s it. I´d expect that it still won´t be the stairs but the usual aisle congestion that will slow down boarding.

I´m not sure if any airport is yet planning to use both the two main deck doors (for accelerated main deck boarding) and the upper deck door...

Yes you will able to board from both decks. Also, even if you only board from one door, the staircase is much wider than the one on the 744. And there is an extra staircase at the ass end.

I do not believe that any airports are equipped with triple-jetways, although if they really wanted to, they could hook up the double-jetway to the main doors and use a jetway from the next gate to go to the right-side upper-deck door. Seeing as how few wide-bodies are boarded through two-doors, I doubt that we will see three doors being used.

Thanks guys, anyway it is a thing to consider by Boeing if they launch an A380 competitor.
