Why is the passenger door up and down on the left side of the plane?

If you pay a little attention, you will easily realize that the door to the passenger up and down is on the left side of the plane (in the direction of looking towards the plane). Why is the left and not the right? Everything has its reasons, let's see how experts explain this.

1. Why is the airplane wing not so high in flying tape?

When the airline industry was just born, the aircraft had to move close to the building to pick up and drop off passengers, not to take the bus to the place where the plane was parked. At that time, the pilot's seat was placed on the left, and in order to easily observe and prevent the wing from getting entangled, the aircraft was forced to approach the building from the left. So for convenience, not having to go around to the other side of the fuselage, the passenger door up and down is designed on the left.

Later, when there were passenger cars coming to park, the airport and the control of the aircraft became more complicated, this model was still fixed to this day.

In addition, the passenger pointing up and down the plane at the left door is related to safety. The activities in and out of the luggage compartment usually only take place on the right side of the plane so there are regular means of traveling on this side. Therefore, in order to reduce the risk of injury from moving vehicles, a clear separation between passenger-specific doors and ground service operations is necessary.
