Why is the pressure button in the plane necessary?
The principle of physical is that the pressure of air decreases with height. The person can breathe only in a certain barrage. So air pressure is controlled inside the plane. There is no scope for error in this system, because this mistake can cause travelers to die. So you know the whole system If the plane flies to the height, then the air pressure decreases. Since the plane's structure is able to withstand this difference. But the passengers inside the aircraft have to keep the same air pressure. The order in which the pressure to be created is called the cabin pressure control system. Air pressure is low at the height, but on the ground it is more. Therefore, pressure on the air with the help of the engine inside the plane is kept on an ordinary ATM. This pressure is controlled by specially made valves based on the height of the plane simple and straightforward answer, because we need oxygen. We know that the level of oxygen goes down at a higher altitude. This is a misc
