Is There A Possibility To Open The Door Of The Plane During The Flight?

Many travellers still worry about the possibility that aircraft doors would open during a flight. Though reasonable, this anxiety stems from misinterpretation rather than fact. Let’s explore the mechanics of aircraft doors and the physics controlling their operation to help us to relax these concerns.

Ron Wagner, a seasoned US Air Force veteran, says technically the door can open if you are able to pull a force of three to four tons. Sometimes flight attendants report nervous passengers trying to open the aircraft doors, but the sheer force needed makes their efforts useless.

At cruise height, the average force applied on an airplane door is shockingly three to four tons. The pressure differential between the cabin and the outside atmosphere generates a force between 181 and 362 kg even when the plane is on ground.

To avoid abrupt pressure shocks damaging passengers’ eardrums during takeoff, airlines deliberately pressurize the cabin while the plane is still on ground. This preemptive action also supports the door security.

An airplane’s door are made with a special locking mechanism. Closed they fit the outer frame like a plug, which explains the term “plug-doors.” This design guarantees that, instead of depending on sophisticated locking technologies that might perhaps fail under pressure, the force of air pressure works in favor of keeping the doors tightly shut.

The fact that airplane doors open from the outside is another absolutely important feature. Anyone inside the cabin cannot physically open the doors during a flight thanks to this design element.

In aviation, you really need to be on the side of laws of physics. Airline doors’ design makes use of these laws to preserve their integrity under very demanding circumstances. Working with physics instead of against it guarantees the stability of airplane doors, so guaranteeing the safety of every passenger on board.
