Pilots use barometers to see the air pressure from the plane.
pilots use barometers because they don't want to crash because of the air pressure might be high
Because they need to measure the air plane
They wear diapers.
Depending on what type of plane, it'll be a wheel or a joystick.
Scientists use mercury barometers and aneroid barometers to measure atmospheric pressure. Mercury barometers measure pressure by balancing the weight of mercury against atmospheric pressure, while aneroid barometers use a flexible metal box to detect pressure changes.
Military or civilian, the plane that is being described is called a "trainer;" in some cases, a "primary trainer."
Mercury and aneroid barometers.
The two main types of barometers are mercury barometers, which use a column of mercury to measure air pressure, and aneroid barometers, which use a small metal box that expands or contracts with changes in pressure to indicate atmospheric pressure.

meteorologists use barometers
A lot of companies use a simulator to train pilots so the trained pilots can expect how one can fly up in the air. One will be trained so he won't make any mistakes or get into any accidents on the plane.
