Explain Why Aircraft Doors Are Always On The Left Side

Why is the aircraft door on the left side (Freepic)

YOGYAKARTA - For people who often travel by air, of course they already know that the plane's door is on the left. This door is used for passengers to enter the cabin or when they leave after the landing plane.

Many passengers wonder why the aircraft door is on the left side? This fact is indeed interesting to swallow because airlines always design the door on the left. Why not make the door on the right side of the plane?

Although airplanes are not new technology, there are still many people who do not know the intricacies of the aircraft. Including the reasons why the aircraft doors are always on the left, not on the right.

The reason for placing the aircraft door on the left is explained by Michael Oakley, an executor of The Aviation Hostorian. He revealed that the commercial aircraft was originally designed with passenger doors on the left side due to tradition.

In the past, there were many terminology in the world of aviation that adapted from maritime terms such as steering, cabin, cockpit, nodes, and others. Meanwhile, the construction of the aircraft doors on the left side aims for efficiency.

The concept of aircraft transportation is the same as ships and boats that have a port side. The side of the ship is usually approached by the dock to dock at the port. So people are also used to getting on the boat from the side of the port which is on the left.

In addition, the steering position is usually located on the right side of the ship. So goods or passengers will usually be on the opposite side, namely the left side of the ship. This tradition is then also applied to airplanes.

This tradition was then used on airplanes. In the 1930-1940s, United Airlines airline implemented an airplane door on the right. However, because more and more people use airplane transportation modes to travel, it is considered more efficient if all passengers ride from the same side and the same terminal.

Matthew Burchette, senior curator at the Aviation Museum in Tukwila, Washington, said the plane's door to the left had something to do with the pilot's seat on the left. The airport was then built with a gate on the left, so the pilot could take into account the distance of the sea better as it slid into the gate.

Quoting from aircraftnerds.com, the pilot of the United States Air Force, explained that the initial airports were designed in such a way that planes could glide near the terminal. With such an airport design, planes can stop and deliver or lift passengers efficiently.

Since ancient times, a pilot has been sitting on the left cockpit seat. By placing the bordering door on the left of the plane, it can make it easier for pilots to assess the wing-end distance from the terminal building. This is the reason why passengers ride and descend on the left side of the plane.

When passengers enter (up) or out (down) from the left door, the right side of the plane will be used for other activities. For example, the right side of the plane is used for loading and unloading, refueling, and others. This situation can save passengers and airport staff time at work.

A similar explanation was also conveyed in the Angkasa Pura I Instagram account. On the account it is stated that the plane door on the left aims to separate the activities of passengers and crew outside the plane. The second reason is to separate passengers from items stored in the trunk of the plane.
