Altitude is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure).
Height above mean sea level is a measure of a location's vertical distance ( height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height.
An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level. The measurement of altitude is called altimetry, which is related to the term bathymetry, the measurement of depth under water.
In response to the pros/cons of feet vs. meters, the big advantage that feet have over meters, is that it allows you to use nice human-memorable numbers for cruising altitudes. In the US, we generally use 500ft for visual separation, and 1000ft for separating IFR traffic from other IFR.

19 de oct. de 2023 · An altimeter is a device that measures altitude, the distance of a point above sea level. Altimeters are important navigation instruments for aircraft and spacecraft pilots who monitor their height above Earth’s surface.
19 de oct. de 2023 · Altitude, like elevation, is the distance above sea level. Areas are often considered "high- altitude " if they reach at least 2,400 meters (8,000 feet) into the atmosphere. The most high-altitude point on Earth is Mount Everest, in the Himalayan mountain range on the border of Nepal and the Chinese region of Tibet.
