You probably noticed that boarding and disembarking passengers from the plane is always done from the left side. But is it necessary or is it just a tradition?

Airport apron buses always bring people to the left side of the plane. To solve this mystery, you need to understand how maintenance works.

Almost all maintenance and pre-flight work is done on the starboard side. This is because there are many hatches on the right side that provide access to important structural elements of the aircraft.

So having people land on the left allows engineers to service the aircraft at this time. In addition, the luggage hatches are also located on the right side.

This allows them to be loaded while boarding without disturbing passengers, reducing aircraft idle time.

It is for the reasons described above that the hatches for boarding passengers are located on the left side. It is more convenient and safer for all parties.

This order was not always there. until 1940 there were no generally accepted design rules for cargo and passenger aircraft.

The place of the landing and technical hatches were regularly changed, which created unnecessary difficulties.
