What do these strips do above the 787 doors?

those are rain gutters
ToeEnvironmental7463@reddit
Gutters.
BeachHut9@reddit
Scratch marks from bird strikes

Channel rain away from the door.
wurstbowle@reddit (OP)
Thanks! That explains why the A330 next to it seems to have them too.
Great_Specialist_267@reddit
Your car has a similar setup…

Is that GRU by any chance?

Most airliners have them, sometimes they're not very obvious though
RazAlGul7@reddit
The sill where the doors seat against the fuselage is a gap, when it rains, water will find it's way in causing a flood,
TommiHPunkt@reddit
most trains too
ticianlicious@reddit
And houses.
NetCaptain@reddit
and our eyes ( for sweat though, not rain )

And cars
tarmacjd@reddit
How have I never noticed these before
berger034@reddit
First time i noticed it was on the Airsorayama livery for Starlux. Probably cause of the dark gray color makes it stand out.
Wikadood@reddit
Also even on CRJ pax doors
BeedleTB@reddit
You'll find it on some train cars too. I guess it's a common solution to a common problem.
Redleg171@reddit
It really bugs me they are all 3 at different angles unlike the Boeing.
t-poke@reddit
What's the aerodynamic and weight penalty on those?
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.
Economy_Link4609@reddit
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.
Just_anotha_redditor@reddit
And they are allligned with the airflow in that region during cruise so they don't generate vortices

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.

CyberKnight@reddit
Allow water runoff in case of door use.
the-only-Chris@reddit
So when you think you’ll be parked for a long time, you can attach awnings.
thisaintparadise@reddit
Drip rails.
whereilaymyheadishom@reddit
Honestly, kind of funny to add them above emergency exits.
pavelowdriver@reddit
drip rails so rain/dirt don't end up on your head
FelisCantabrigiensis@reddit
Gutters. They direct water running down the fuselage away from the door opening.
TomOnABudget@reddit
They're also useful for installing a roof box, awning or roof top tent when you take your plane out to go bush camping.
LateralThinkerer@reddit
You're not gonna strap your canoe to the landing gear like some amateur...
LinguoBuxo@reddit
Also you can pin a mosquito net to it.. dual function
CptJFK@reddit
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.
oboshoe@reddit
Yea. But then once you get it all setup, and realize you need to fly into town for supplies.....
Claudio_VerKnight@reddit
I hate when that happens
Bright_Broccoli1844@reddit
Hee hee
InTheSky57@reddit
You got your answer but damn that's a dirty bird.

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.
One-Reference-7355@reddit
I sometimes wonder how much money they save doing this, since it’s almost always down to that
Puzzled-Formal-7957@reddit
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
snailmale7@reddit
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.
Fabiablee@reddit
you will start to notice them alot on other things too
cyberentomology@reddit
They keep water from running into the plane when it’s raining and the door is open.
dredeth@reddit
Same what you have on your car, more visible on older cars, but it's still there.

Divert rain when on the ground. You notice when boarding - and you are thankful for it!

ah thank you I've found my people over there.

Where the bridge or stairs for passengers and crew
agha0013@reddit
keeps water from entering the cabin as easily when it's raining
water runs down the fuselage and those act almost like gutters diverting it away from the door.
Nousername58@reddit
Drip guards so rain water doesn’t run into the open doors
