magasságmérk

Magasságmérk is a Hungarian term that translates to "altimeter" in English. An altimeter is an instrument used to measure the altitude of an object above a fixed level. This fixed level is typically sea level. Altimeters are crucial in various fields, most notably in aviation and mountaineering.

In aviation, altimeters are essential for pilots to maintain safe flight altitudes and navigate through airspace. They typically work by measuring atmospheric pressure. As altitude increases, atmospheric pressure decreases, and the altimeter translates this pressure difference into a corresponding altitude reading. There are different types of altimeters used in aircraft, including aneroid barometers and radio altimeters.

For mountaineers and hikers, altimeters help in tracking their ascent and descent. This information is vital for planning routes, assessing progress, and ensuring safety, especially in challenging terrain where visibility might be limited. Portable altimeters, often integrated into GPS devices or dedicated instruments, provide this valuable data. Understanding the altitude can also be important for acclimatization to prevent altitude sickness. The concept of magasságmérk, therefore, encompasses a range of devices that serve the fundamental purpose of measuring height above a reference point.
