Hey Guys:
Here I go again with another 737 question, I noticed on a few 737's they have this cool door outline that curves before the actual door ends. My question is why are the outlines painted like this. Also is Southwest going to incorporate this design onto its 73NG's too?

I have no idea what you're seeing or talking about...??? Can you better point it out...? The grey band around the door...? Every single commercial aircraft in the world has that. It's design is to aid rescue workers in finding the door cut out. My guess would be it will draw your eyes towards it. The chrome trim at the bottom..? Nearly every single commercial aircraft has that as well. It protects the door sill from jetway damage

Sure heres a close up:
This close up comes from the picture taken by Rich Schlamp on Flickr.
The area I am talking about is circled in black.
From what I know the actual door its self fits the entire frame, so this is why I ask why the outline ends short of that chrome (dark colored) bottom.

What he is talking about is the fact that the bottom of the door is actually below the outline provided for it. It's easier to see in this shot:

That is the bumper plate I mentioned above... most all commercial aircraft...including Southwest. I don't understand why that airline elected to 'shorten up' the door band and not fully out line it. I've never seen that before

as you can see the door its self ends at the bumperplate, but the actual door outline ends about a foot before it- what I am talking about is the actual door outline ( which is a light gray)

For some reason this airline decided to not fully outline the door. Why I don't know.....

It seems like this is also found on the Airbus planes as well:
For those still scracthing their heads at what I am talking about its in this picture, as you can clearly see where the outline ends and where the door ends.

This laymans explanation...
Remember this door is a plug type. To open it has to go in first and then out - that means that the door has to get smaller somehow. The painted area at the bottom of the door is a panel that opens inward when the door is opened - I'm guessing it's a pressure relief door as well as a means to make the pax door smaller.
Why it's painted differently than the WN 737 below... I have no idea....

Its a stainless steel threshold plate it is attach to the fuselage skin and the door opening . It protects the aluminum structure from the jetways and passengers that would step right on the edge of the door opening.

The only thing above the item I am talking a the door opening, or the door if its closed.
Enlarge the following picture it shows the stainless steel door threshold very clearly and that the door extends below the outlined area:

Yes...you guys are talking about the same thing, just saying it differently! It's apparent that on some aircraft, the door outline does not exactly outline the door. The initial poster noted that and wondered why. You are stating the same thing, but getting hung up on the threshold!

There is a panel attached to the bottom of the door that folds inward on opening. It is not the threshold - the threshold is beneath it.

I think that panel is actually part of the door, not attached to it. In the picture below you can see the door, the panel and the stainless steel threshold.

How can something be part of the door... yet not attached to it? The panel moves inward when opening the door.

I've noticed this on newer a/c recently - mainly 737NGs and new A320s - even on new A330s.
I don't know why the door outline isn't painted all the way down to the scuff plate, but from an aesthetic point of view it certainly looks better.

Here's a 737 sans paint. The panels at the top and bottom of the door are plainly visible.

To get back to the original question, I think that maybe it's just a stylistic choice made by the airlines themselves. There doesn't seem to be a rhyme or reason as to who paints the door trim all the way to the bottom, and who doesn't.
I can't remember...is it actual paint, or is it an adhesive sticker?

That was my point all along, it is an integral part of the door, not something just attached to the door.

Well ok... but the door has lots of parts, "integral" or attached - your choice. Personally I prefer all the parts be attached...
Now, why is the paint different on this bit of the door - attached or integral??

I'm pretty sure that's what he wants to know! Just to be sure, (and with apologies to the guys who's photos I snipped the doors from), this is what he's talking about...
The door outline reaches all the way to the threshold on the Southwest bird, and comes up short on the Copa one. I think you realize that, but he wants to know why? It may be a silly question, but I have to admit that now I am curious too! I'm sure it all boils down to each airline's particular aesthetics.
As for this question: Also is Southwest going to incorporate this design onto its 73NG's too? I guess the answer would be "no" because the photo above is a 73NG, and it goes all the way to the threshold.
25 SXDFC: You hit the nail right on the head! Thank You! That is what I think too! it makes the plane look newer, unlike the old design.
