Answer 1

The correct answer is altitude

Key Points

An altimeter is an instrument used in aircraft to measure the altitude of the aircraft above a fixed level.
It is a crucial device for ensuring the aircraft maintains a safe altitude, especially during takeoff, landing, and while flying in mountainous regions.
Altimeters can be of different types, including barometric altimeters, which measure altitude based on atmospheric pressure, and GPS altimeters, which use satellite data to determine altitude.
Proper functioning of the altimeter is essential for the safety and navigation of the aircraft.

Additional Information

The barometric altimeter works on the principle that atmospheric pressure decreases with an increase in altitude. It uses this pressure difference to calculate the altitude.
Modern aircraft often use a combination of barometric and GPS altimeters to enhance accuracy and reliability.
Altimeters must be regularly calibrated to ensure accurate readings, as factors like temperature and pressure variations can affect their accuracy.
In aviation, maintaining the correct altitude is vital for avoiding obstacles and ensuring safe separation from other aircraft.
