What is the 'eyebrow' fairing over the front passenger door for?
I've noticed it a few times on commercial aircraft. You can see one here: http://www.airliners.net/open.file/503971/M/
I've always assumed it's aerodynamic. It's always canted forward about 8 degrees, as if to encourage a vortex...but the door is flush to the fuselage, so why?

I believe the angle it's at is so that it is aligned with the local airflow around the fuselage. Not entirely sure about this, but given the choice why wouldn't you build it that way?
I hear that one asked as the pax stream in. On the way out they ask why there is an eyelet on top of the wing a few feet outside of the emergency exits. I used to fly a CRJ and it was common to be informed that our nose tire was flat.
Felix, I wasn't disputing the purpose, merely commenting on why they're mounting at the angles they are. They could slope steeply backwards, shallowly backwards, forwards by whatever amount, be chevron shaped etc etc & still stop drips.

Loma,
Some aircraft (i.e. 737NG) have integral airstairs but most (notably Bae-146 shown in pickie) don't. So freezing water in the stairs probably wouldn't be an issue. It's just a comfort feature for the pax. BTW what's a mechanical pathologist??
