Doors and emergency exits
 

On the Airbus A320 and Boeing 737 families with overhead wing exits, are these exits numbered or refered to as l/h and r/h overhead wing exits?

exits
 

they are refereed to as doors 2 or 3 dependant on how many pairs of doors in total the a/c has:

e.g. the 737 - 800 has 4 pairs of doors

l1 and r1 at the front
l2 and r2 at row 15
l3 and r3 at row 16
l4 and r4 at the rear

this applies accross the 737 family.
the doors are not overhead but at mid cabin height

I have to disagree, self help exits do not have a designation. On a 737, 1 left and right are at the front and 2 left and right are at the back. Same on a A320.

Emerg exits
 

Doors are doors and exits are exits. This means that on the A320 you have doors 1 (L and R) forward, doors 2 (L and R) rear and 4 overwing exits. As they're not doors they are numbered in the same way.

well for the airline i presently work for all self help exits on 737 (all types) and 767 - 200 are designated as numbered doors. an exit is just another name for a door. it must vary from company to company.

Seasick - why do you ask? :)

banewboi, who do you work for out of interest? It's just I've never heard of the self help exits having a number designator before. The manufacturers refer to the rear doors on the 737 and A320 as Doors 2.

at present i work for tfly (ex by) but i've just accepted ba. i didn't know that was the way the manufacturers reffered to them but that has always been procedure on all a/c types (including the airbus that we tested a few years ago) all doors or exits were just numbered in sequence to their position on the fuselage. i.e. rear doors are doors 3 or 4.

it's interesting to see these kind of differences that although small could be extremely confusing. something i noticed during the interview (similarly small but different but otherwise unrelated) i was told to adopt the brace position which is feet forward of the knee's whereas tfly is behind the knees, i would have thought this should be standardised by the caa as they are completelt opposite!!

All airlines do indeed have diferent names for their doors, and providing the CAA (or local governing body depending on where the airline is registered) have authorised it, it's fine.

Industry standard for a B737-300 for example is

D1L D1R

overwing exits

D2L D2R

And the reason you would have adopted the brace position with feet forward of the knees would be because you are demonstrating the crew position in a rear facing seat.

Feet should always be nearer the tail of the aircraft. So forward facing brace, feet back. Rear facing, feet forward.

It's to stop your feet flying forward in a sharp brake, impact or jolt. Like all rules governed by the CAA, they are as a result of various Air crash investigations, and policies change as a result to improve safety and learn from mistakes.

Another example, the reason you demonstrate the seatbelt unfastening is following a crash where bodies showed sign of trying to open their seatbelts like in a car, and perished as a result. The demo clarifies the difference in the hope they'll remember.

Also lifejackets used to be inflated inside. Until an aircraft ditched and was totally waterlogged meaningmany floated to the ceiling unable to get lower to escape out of a door. Adult lifejackets inflated on a child is different because alot of the air pressure had been released as the child is light and an adult can assist them to dive without too much pressure.

The brace position has been known to save many lives too.

Seat backs remain upright to protect the back and front of the head when bracing and if they are down at all, anything that hits the back of it just gives that little bit more momentum to knock the structure out of place and could collapse a seat exit into the row infront.
