737 Over wing exits

[embpic1]

I was just looking at the Turkish 737 in Amsterdam and noticed the over wing exits are hinged at the top and they fold up. Is that a Turkish thing (option) or is that the way Boeing is doing them now?

They're like that on all the NG's.

They're very slick. Pop off the cover, pull the handle. Kinda like a Delorean without the time travel.

DC-3's were hinged at the top also. The more things change, the more they stay the same.

"very slick"

unless you crash upside down

They'll still open. Unless the fuselage is on top of them.

They're hinged and open out? I thought doors that just popped outward were the bane of pressurized jets. That's why we had to pull the old doors in and then set on the seat. You never had to worry about a Pax opening a door in flight because you might have upwards of 8.5 psi holding it shut.

Cool! How does it work?

they are locked shut if the engines (or maybe just #2, I forget) are above a certain RPM.

the other 'interesting' feature is that you need to open them with your palm up, if you stick your hand in palm down, which seems natural, the door opens with such speed and force that you may have a broken forearm for your trouble.

PSEU switch. Proximity Switch Electronic Unit. Glorified "squat switch." Controls the locking of the doors when power levers advanced for flight. In a nutshell.

 

[CRJ's suck]

I thought they weren't locked until groundspeed reached 40 kts. I may be wrong though, it's happened before.
