Lines Above The Doors...

Thu Sep 25, 2003 8:43 am

Apologies if this has been discussed before, the search didn't turn up anything. If you enlarge the picture below, especially in the large version, one notices lines the width of all the cabin doors above the doors. Can someone explain what these are/why they're there...?

I'd assume they are there to stop water etc. running down over the door when the aircraft is on the ground.

He's correct--it's to channel the water away from the open doorway.

Think "very small rain gutter"...

Draingutters, yes, kinda like all cars and trucks used to have (before they went "aero", of course). You will notice that they are mostly all installed at an angle when viewed from the side to directionally channel water to front or rear, depending on door location, and not interfere with airflow...jack
all best; jack

Here's a shot that shows them pretty well...

The front ones (at least on the 737s and some other Boeings) is at more of an angle to compensate for the nose curvature, which you can see in the photo above. The one over the aft service door is closer to being level with the aircraft...

Being level is not a good thing, it would allow water to sit in the channel, inviting corrosion. So you will never see one of those gutters perfectly level.
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

Agreed; that's why I said "closer to being level"...  Big grin

The 747 is Kind of flat to the Jetway so we have to use a plastic gutter we rigged up so the PAX dont get wet..only when it rains hard, and it does happen on out Tropical Island of Saipan..
