A321 Type C Exit / Door 2L

Mon Jun 08, 2009 3:23 am

I have a question relating to the the Type C doors of the 321. While 2L/R and 3L/R are certified as Type C doors, the 2L door is considerably larger - closer to the size of the main doors.

At doors 2 I have noticed that some airlines do not have overhead bins above both 2L and 2R. Others have bins only above 2R and some have bins over both. All 321s have overhead bins above 3L/R.

The slides are Doors 2 and 3 are stored in the aircraft, under the door. The inflation cylinders are in the overhead bins above the door. If there is no overhead bin above the door, where is the inflation cylinder located?

As the 2R door is of the smaller size, what is the benefit of not having the overhead bins above? Evacuation certification?

Regarding the 2L door, is it possible for it to be used as a pax entry door? I have seen Airbus material which indicates this. Do any airlines make use of this feature? Obviously driving an aerobridge to this door would be extremely difficult! What about stairs? The door is a full-sized door, yet on many configurations overhead bins cover the top third of the opening. Though in the first example above, Lufthansa, it seems that the Doors 2 area is set up for this purpose (pax entry).

Thanks in advance.

I'm no expert on the A321, but here's a guess from my end:

As you said, the 2R door is smaller than the 2L door (looks to be about the size of the 3R/L doors). I would guess that this is very specifically done to enable 2L to be used as a passenger entry door. However, as they are certified as a pair of doors (for passenger egress purposes), they can only be certified as Type C due to the 2R door being smaller. That's assuming that door are certified as pairs - which is what I believe happens.

I've quite often boarded AA 757s through the 2L door (similar positioning to the A321's 2L door). I'd guess it depends on the gate setup more than anything else.

Perhaps the airlines that have the overhead bins in front of 2L don't use that door for boarding.

The bottles are still in the overhead area. They don't need the entire bin space though, which is why you still see a box in the overhead area above the exits even though there is no luggage bin. This smaller box is enough to hold the bottle.

You can see how big the bottle box is in this video:

We get very few A321 nightstops here, its usually an A319.
Last month a A321 nightstopped, and as I was checking the cabin, the 2R door opened. Catering had driven up, saw the 8 door layout, and thought it was a B757. Catering guy comes through 2R door and looks at me. "Where have the galleys gone?" (Our fwd galleys on B757 are at doors 2)
It was my first A321 nightstop as well. I thought that 2R was an emergency exit only, up till then I didn't realise it was an ordinary door.

Thanks for your replies!

I am still uncertain as to why the airlines choose different bin layouts at Doors 2 L/R.

And do any airlines use Door 2L as a pax entry door?

At bmi we have no overhead lockers at L2. It is often used as a boarding door, especially when the aircraft has come in as international / domestic and is departing domestic / international. A jetty is attached to L1 to disembark the passengers into the correct part of the terminal, and passengers are bussed out and come up stairs to L2. As far as I am aware, L2 cannot have a jetty fitted due to the proximity of the engine.

Thank you so much, BWA flyer!

Does that make the L2 door a Type 1 door at BMI? Or still Type C?

On BMI 321s does L2 door have a cover over the door operating handle, like the other Type C doors? Does the L2 door have the slide pack on the door in this arrangement, or under the door as with the other Type C exit?
