Did you suppose that at a single point, airplanes existed without having a heating system in them? When every one of us fly on airplanes, every one of us rely heavily on the Heating, Ventilation, plus A/C equipment on the plane.
- In fact, in most airplanes, there are many vents above each person’s head that allows cool air from the Heating, Ventilation, plus A/C equipment to keep us comfortable! Technically, airplanes mainly use a heating system on their plane.
They don’t undoubtedly need an a/c on the plane because the air outside is chilly cold at that height, without the Heating, Ventilation, plus A/C unit, most of us would have to bundle up because every one of us would be absolutely cold. In fact, people used to ride on planes before they installed heating systems on them. If you were the pilot of a plane before they had heating systems, you would have to wear thick suits to stay warm. It was even more hard to be a passenger on a plane before the Heating, Ventilation, plus A/C units were created, however obviously, back then, planes were not used for public travel which is why Heating, Ventilation, plus A/C units were not necessary! However, I am thankful that they have Heating, Ventilation, plus A/C units on planes now. I travel on a plane many times per year, plus I would never want to have to sit in a plane without a heating system to keep myself and others warm. I enjoy that most planes are warm, plus they have the vent in the Heating, Ventilation, plus A/C equipment that pumps in the cold air from outside. The ability to be able to control the temperature in each seat is nice. I wouldn’t ever want to go back.
