What do these strips do above the 787 doors?

I can see having them on the main doors and even the rear door for catering and servicing, but over the emergency exists too? If you're using those, getting wet is the least of your concerns.

Remember - on a 787 those doors can be used for catering or boarding with multiple jetways, so they are opened regularly. You won't see these on over-wing exits I think.

And they are allligned with the airflow in that region during cruise so they don't generate vortices

Markiza sie wysuwa jak pada deszcz. Albo swieci słońce.

Sure helps channeling water, but my money are on while airbridges are used. Not sure airbridges is the correct term, we call them fingers here, but I guess.. when the airplane is fingered sounds way more wrong.

Allow water runoff in case of door use.

So when you think you’ll be parked for a long time, you can attach awnings.

Honestly, kind of funny to add them above emergency exits.

drip rails so rain/dirt don't end up on your head

Gutters. They direct water running down the fuselage away from the door opening.

They're also useful for installing a roof box, awning or roof top tent when you take your plane out to go bush camping.

You're not gonna strap your canoe to the landing gear like some amateur...

Also you can pin a mosquito net to it.. dual function

Is the beer-holder optional or a fold-out?

FelisCantabrigiensis@reddit

You've seen the seating plan for Ultra Basic Economy fares, I see. They're up in the roof box.

Yea. But then once you get it all setup, and realize you need to fly into town for supplies.....

United likes to not clean the outside of their planes. UA easily has the most beat up looking planes of any of the US major carriers.

I sometimes wonder how much money they save doing this, since it’s almost always down to that

From the outside. Inside it is American, as far as I can tell.

[-]

I_like_cake_7@reddit

I would have to agree with that.

[-]

3rd-party-intervener@reddit

They don’t care about clean

These strips align with the wind when the airplane has reached it's optimum flare attitude..... OR, like everyone already said... to keep the rain from running into the door when it's parked at the gate.... I like my first suggestion better though.
