3/2/2023 0 Comments Altitude definition![]() Flight Level (FL) A surface of constant atmosphere pressure which is related to a specific pressure datum, 1013.2hPa, and is separated from other such surfaces by specific pressure intervals. VFR flights (in VMC) may be planned and executed at lower levels. Space extended upward height the perpendicular elevation of an object above its foundation, above the ground, or above a given level, or of one. Definitions Altitude The vertical distance of an object measured from mean sea level. For example, 42 means 4200 feet.īy definition, AMA is only applicable to IMC. The larger one represents the thousands of feet and the smaller one is for the hundreds. In geometry, the altitude is a line that passes through two very specific points on a triangle: a vertex, or corner of a triangle, and its opposite side at a. the height of anything above a given planetary reference plane, especially above sea level on earth. The AMA is maked on charts using two digits, usually one larger and one smaller. ![]() between 35 and 36 North and 27 and 28 East). ![]() The measured distance above a fixed object, e.g., the distance above sea level, or. the area between lattitude X and X+1 and longitude Y and Y+1 (e.g. A raised area that protrudes above the surrounding area. Although the term altitude is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. The exact definition and reference datum varies according to the context. While the ICAO definition allows for different sizes and shapes of the area, the most common format used is a 1-degree quadrilateral, i.e. Altitude or height is a distance measurement, usually in the vertical or 'up' direction, between a reference datum and a point or object. Normally this means 2000 ft over high terrain or in mountainous areas and 1000 ft otherwise but different figures can be specified by the competent authority. : the height of something (such as an airplane) above the level of the sea. 1 DescriptionĪrea minimum altitude (AMA), sometimes referred to as minimum off-route altitude (MORA) provides minimum obstacle clearance above all obstacles in the area. Britannica Dictionary definition of ALTITUDE. ![]() The minimum altitude to be used under instrument meteorological conditions (IMC), that provides a minimum obstacle clearance within a specified area, normally formed by parallels and meridians. ![]()
