altimeter

 

[ ælˈtɪmətər ]

Noun
Context #1 | Noun

aviation measurement

An altimeter is an instrument used to measure the altitude of an object above a reference point, typically the earth's surface. It is widely used in aviation, where accurate altitude readings are essential for safe flight operations. The device works by measuring atmospheric pressure, which decreases with an increase in altitude. There are various types of altimeters, including barometric altimeters and GPS altimeters, each using different methods to determine height.

Synonyms

altitude meter, elevation meter, height gauge.

Examples of usage

  • The pilot adjusted the altimeter before takeoff.
  • Using a GPS altimeter, the hiker tracked their elevation gain.
  • The altimeter provided critical data during the flight.

Etymology

The term 'altimeter' is derived from the Latin word 'altus', meaning 'high', and the suffix '-meter', which indicates a measuring device. The concept of measuring altitude has existed for centuries, with primitive forms of altimeters being used by explorers and mountaineers. The modern altimeter was developed in the 19th century with advances in barometric pressure measurements, allowing for more accurate and reliable readings. The use of altimeters became standardized in aviation in the early 20th century, enhancing flight safety and navigation. Over time, the technology has evolved, incorporating digital systems and GPS technology, broadening its applications beyond aviation to fields such as meteorology, mountaineering, and even outdoor sports.
