A319/A320 Door Designation

[LandASAP]

Hi @ All,

how are the aft cabin doors on A319/A320 officially designated?

Are they 3R/3L or 4R/4L ? I'am not quite sure but if i remember correctly the dual overwing emergency exits are in terms of designation officially only One. Which would mean that 3R/3L is the correct designation for the Aft Cabin Crew/Pax Doors. Is that correct?

Greetings Michael

The AFT doors were designated 2L and 2R.

But I did notice in the generic CCOM about 18 months ago they changed to 4L and 4R, I assumed this was for commonality with other types but never checked.

I suspect that, from the point of view of the manufacturer and regulators, you can call the doors anything you like as long as you have a way of identifying each unambiguously.

Interestingly, Airbus itself has changed the way it refers to the doors, at least in its Airport Characteristics manuals, as the narrow-body family has developed.

Initially, for the A319/A320 (left-hand side only, forward to aft), the doors were referred to as:
Fwd passenger/crew door
Emergency exit door [optional on A319]
Emergency exit door
Aft passenger/crew door

Later publications changed that to:
Door 1L
Forward overwing exit
Aft overwing exit
Door 4L

Similarly for the standard A321 (where the emergency exits aren't overwing), initially:
Fwd passenger/crew door
Emergency exit door
Emergency exit door
Aft passenger/crew door

Standard A321 later:
Door 1L
Forward emergency exit
Aft emergency exit
Door 4L

And A321 ACF:
Door 1L
Forward overwing exit
Aft overwing exit
Door 3L
Door 4L

Confused? :O
