Because they need to measure the air plane
S(he) uses an altimeter which a kind of airborne barometer.
Pilots adjust a barometer to ensure it reflects the current atmospheric pressure at their location, which is essential for accurate altitude readings. Since atmospheric pressure decreases with altitude, an uncalibrated barometer could lead to incorrect altitude estimations, potentially resulting in unsafe flight conditions. By setting the barometer to the local pressure, pilots can maintain precise altitude awareness, enhancing safety and navigation accuracy.
the answer is yes
the answer is yes
how do meteorologist use a barometer
It is called a barometer, first developed in the 1600's
I chipped the glass tabletop when I dropped the barometer.
no
no
meteorologists use barometers
It does not use mercury.
i checked the barometer to see the air pressure
