What is the curved line of metal above the outside of airplane doors for? something to do with attaching the jetway to the plane?

It's a rain gutter used to direct water away from the door opening. -

One's on our planes are horizontal... Sooo it seems it depends on the aircraft, how they are mounted.Originally posted by BoeingBobby View Post-Not an Airbus or Boeing guy here.

Here are several examples of rain gutters installed at an angle.I have never seen an angled one!
Note that gutter over the L2 door on the A330 is horiziontal, while all the others are angled to allow the water to run away from the door opening.
Also note that none of them are curved.Comment

Hey, when your wrong you wrong, what can I say. I was interpreting angled as a v shape in my mind. Hey I am an old guy, mind isn't what it used to be. LOLOriginally posted by 474218 View PostHere are several examples of rain gutters installed at an angle.

It's aligned with air flow.

The rain gutter alignment has nothing to do with air flow, only water flow.Originally posted by bob m View Post
On the L-1011 the rain gutters were originally installed horiziontally above the doors. This allowed the rain runoff to over flow the gutter and spill over into the door opening. Later build aircraft had the gutters angled.
Original installation:
Final configuration:
In the second L-1011 photo note the different angle between the L1 door and the L2 gutters.Comment

On a cylindrical surface only a horizontal gutter would not be curved. Try it with a business card on a cylinder. Of course the gutter may be flexible enough not to require a pre-curve.Originally posted by 474218 View PostHere are several examples of rain gutters installed at an angle.
