How does the air pressure in the cabin change when the plane lands or takes off?

When the plane lands or takes off, the cabin pressure will change as follows:

1. When the plane ascends or descends, the air pressure in the cabin will change accordingly. Because the air pressure in the cabin changes with the flying height, the passenger's eardrum will also be adjusted accordingly. When the plane is ascending or descending, passengers can adjust the air pressure in the eardrum by chewing gum and food, thus avoiding ear discomfort.

2. When the plane stays on the ground or flies at a low speed, the air pressure in the cabin will remain at the ground air pressure level, and the passengers' ears will not feel uncomfortable at this time.

3. When the plane is cruising, the air pressure in the cabin will be kept at a stable level, and passengers' ears will not feel uncomfortable at this time. However, when the altitude of the aircraft changes, the pressure in the cabin will also change.

Therefore, when the plane takes off and lands, the cabin pressure will change with the change of flight altitude. Passengers need to pay attention to the change of air pressure and take appropriate measures to avoid ear discomfort.
