if aircraft is flying in high altitude is it possible to open the door?

Answer 1

yes, but everything not tied down will get sucked right out the door.

Answer 2

To answer your question correctly you have to understand a little about aircraft pressure differential and structures on commercial aircraft.

Each pressurized aircraft has a determined maximum pressure differential, which is the maximum differential between cabin and ambient altitudes that the pressurized section of the aircraft can support. All commercial aircraft have a negative pressure relief valve to equalize pressure in the event of a sudden decompression or rapid descent to prevent the cabin pressure from becoming higher than the ambient pressure.

AIRCRAFT CABIN VOLUME RATIOS
Aircraft Type Cabin Volumes in Cubic Feet Ratio
DC-9 vs CE-650 5,840 vs 576 10:1
B-737 vs LR-55 8,010 vs 502 16:1
B-727 vs NA-265 9,045 vs 430 21:1
L-1011 vs G-1159 35,000 vs 1,850 19:1
B-747 vs Learjet 59,000 vs 265 223:1

You have to understand the doors on large commercial aircraft are called plug style. Meaning they are shut from the inside and get tighter as the aircraft is pressurized. So if you take the above cubic feet chart inside of an aircraft and apply it to the door we are talking tons of pressure holding the door closed. Needless to say it cannot be opened from the inside at altitude unless the aircraft is somehow de-pressurized.

Even if a pressure seal is broken the pressure differential will push the door up against the rubber seal. Some pressure will escape, but the door will hold and sill cannot be opened. The pressure relief valves will close to aid in equalizing the inside pressure.

So to answer your question No you cannot open the door.

Answer 3

Possible yes. If it's a pressurized aircraft however you will rapidly lose cabin pressure and this could damage the aircraft or cause someone to be sucked out the door. And since whoever opened the door is most likely to go out with the air, I'd suggest you don't try it. In a unpressurized aircraft it will have very little effect.

Answer 4

The Hulk may be able to do it, but you couldn't.

Aircraft at altitude are pressurized to maintain a livable oxygen pressure for the folks onboard. This pressure differential is expressed in psid (pounds per square differential). The average cruise differential is around 8 psid. Now take your standard aircraft door. It's about 75 inches high, and 40 inches across. Do the math and that's 3,000 square inches. At 8 psid that's 12 tons of pressure holding the door closed. Even the mechanical advantage given by the standard door operating handle won't give you enough help to move the door against that.

Answer 5

Technically, yes though anyone who wants to do it would be crazy. At high altitudes, a commercial aircraft is pressurized, so that passengers can breath normally rather than the thin air at the altitudes. Because of this, the air pressure inside the airplane is many times greater than outside. Therefore, if anyone opened the door at high altitudes, a huge amount of air would be forced out as the pressures equalized. This creates a giant suction out the door, sucking anything no secured outside, and even ripping the door off it's hinges. Following the decompression, all the people inside would likely pass out due to the lack of oxygen at the altitude.

Many instances happened in history. None involved a passenger door, but all suffered decompression problems.
United Airlines Flight 811 is an example, as is Helios Flight 522.

Answer 6

Yes its possible. We used to take playing cards and peel back the number 2 entry door seal and let the cards get suck out. Only on long missions and we were bored though ;). So if I can peel the door seal back with 2 fingers, yes the door can be opened in flight. Not a recommendation though. Besides, the 10's doors went up into the fuselage and not out.

Answer 7

No , not at high altitudes, and im presumeing your speaking of a pressureized airliner in todays world, When you are on the ground the pilots presureize the plane before take off,

Now id something pierces the skin of the plane or he depressureises it , you will know as th oxygen mask will fall down,,, anything above 10,000 ft will be sucked out if you open a door,

Case in Miami an american airlines plane landed from New York but this new type of jet was malfunctioning and a valve to depresserize did work so fast. Well the flight attendant went to open the door and whoosh was suck out onto the runway.( tarmac)

Answer 8

It all depends on the aircraft an unpressurised aircraft then yes. A pressurised aircraft with plug doors would be impossible as the presurised atmospher inside would prevent the door opening most modern airliners use an ouward opening plug door.

Answer 9

On pressurized aircraft, the doors are "plug type." They will have to open inward before they're allowed to swing outward. The cabin pressure helps keep the door firmly in place. I guarantee that you'll NEVER be able to open an aircraft (pressurized) door in flight.

Unpressurized aircraft are another matter. Yes it can be done.

Answer 10

No, in a commercial pressurized aircraft it is impossible to open the doors. They are made so that they must swing inward before they can rotate outward . Have you ever tried to open a car door at 70 mph? Imagine going 600 mph.

Answer 11

it is possible and only do it if you want to DIE because at higher altitude the pressure outside is much lower than inside the plane soeverything gets sucked out to lower pressure and you will fly out and when u make impact you will die
