Or would it be too much pressure? What about the machine controlled ones on the heavies?

380,

as a flight attendant i say that Its impossible to open a door or an emergency exit during a flight regardless of how heavy it is or how its operated. this is because the pressure inside the cabin during a flight is much much greater than the pressure outside, so the doors are being pressed in their places.. and if you notice, all the doors in order to be opened whether they are opened upward, pushed outward or swung open, they mus be pulled inside and then pushed outside then opened.. and with that amount of pressure, you cant pull them inside.

The amount of force required is most likely thousands upon thousands of pounds. Even at a 1 psi pressure difference, a 6x2.5ft door would require around 2200lbs open.

This said, can a door be opened if the plane were to depressurize, or would the 500 mph wind across the door create enough suction to dissallow the door from opening?

i believe there is some kind of procedure in which the doors can be slightly opened to let smoke or whatever escape from the cabin.
i recently read on a Lufthansa flight (747-200) there was something hanging out from one of the doors and they opened the door and pulled it in (it was some part of the emergency slides).
however, this is only possible at low velocities and low altitudes due to facts already mentioned in earlier posts...

Just two words : NO WAY....!!!!!!!!!!!!!!!!!!

Pressure diff = 7 to 8.5 psi

No procedure to open a door in flight for smoke removal. Only a cockpit sliding window, with aircraft depressurized !!!

I suppose you could do it if the aircraft was depressurized.

I was F/O in an unpressurized Convair cargo flight once and we heard a funny noise from the back that we thought might be the overwing exit coming open. I said we best leave it alone, since they opened inward, and take care of it on the ground. The Capt. wanted to go back and fix it, though. So he did...no big deal.

No way you can open an emergency exit in a pressurized aircraft, though.

Two things:

1) I have seen procedures to open a 747 door at low altitude to evacuate smoke if needed. Of course, Airplane has got to be de-pressurized.

2) I recall, when I was working on DC-8 airplanes, a type of emergency exit that was called "jet escape". I am not sure if these exits would or would not open when A/C is pressurized.

On today's A/C, I do not believe it is possible to open an emergency exit during a pressurized flight.

Remember the incident a year ago aboard that A330 in the Phillipines. That robber opened the passenger door as the aircraft was circling at a low altitude.

Also remember the DB Cooper incident (but God knows what happened that time).

certainly, exits cannot be opened at cruising altitude but they can if the aircraft is at low altitudes, thus low pressure, or if it is depressurized...
