I may not be the most accurate of sources but I think its to deflect rain away from the doorway when there is no jetway attached. I.e. when there is the galley service truck or in the even of an evacuation in the rain. That's just my $.02  Wink

I believe its a miniature gutter, to keep rain from dripping onto your head when you walk through the door. Feel free to correct me if I'm wrong.

Its there so that rain doesent drip down the aircraft door, instead it goes down the "line thingy" and onto one side away from embarking/disembarking passengers.

I think it's pretty much like a rain-gutter kinda thing. I've seen 'em a rew time. When it's rained water can still make it's way through the gap between the a/c and the jetway so it kinda deflects the water to the side.

Trust me, it's a rain gutter. On the 400 they're at all the main deck doors. If they were some type of "buckle zone" they would be at the upper deck doors. If you look, they're absent from there.

It's called a drip rail(rain gutter). Trust ME, I've replaced my share of them. It isn't there for the absence of a jetway as the rain will pretty much come in the door anyway. It does route water running down the fuselage away from the door. The canopy on the jetway doesn't make a water tight seal so the drip rail keeps most of this water from reaching the canopy.

I've always been curious; how are they attached? Welded? Rivets? Glue?

They are attached with solid rivets, which are shot on wet(with sealer), and sealer between the rail and the fuselage. They are then edge sealed with an aerodynamic seal.

I wondered that a lot when I first saw 777s, and noticed most planes had them. When I got up close and noticed it, I found it funny how quickly it's purpose came to mind. It was like, "Oh! It's to deflect water from falling into the cabin!"  Smile

The best part, that no one has mentioned, is that they are aligned with the relative airflow so they have the least amount of drag, and the pic shows it perfectly.

Here's a pic that I took that actually just got rejected but I'll revamp it until its a.net needs but you can see that it is clearly doing its job over the door of this United 777-222;

It was this picture that made me think about this same question but was afraid of getting flamed for my lack of the "simple things". Glad to hear its what I thought and that it isn't "as simple" as CCA has pointed out.

Thanks,

Matt
