Miami Homestead General Aviation Airport ( FAA LID : X51 ) is a county-owned public-use airport in unincorporated Miami-Dade County , Florida , United States , located 4 miles (6.4 km) northwest of the central business district of Homestead .
6-521: The airport was renamed from "Homestead General Aviation Airport" to "Miami Homestead General Aviation Airport" in December 2014 by the Miami-Dade County Commission. Homestead General Aviation Airport covers an area of 960 acres (390 ha) at an elevation of 9 feet (2.7 m) above mean sea level . It has two asphalt paved runways : 18/36 is 3,999 by 100 feet (1,219 x 30 m) and 10/28
12-439: Is 3,000 by 75 feet (913 x 23 m). It also has one turf runway: 9U/27U is 2,500 by 150 feet (762 x 46 m). For the 12-month period ending June 18, 2002, the airport had 72,084 aircraft operations, an average of 197 per day: 70% general aviation , 1% air taxi and 1% military . At that time there were 64 aircraft based at this airport: 66% single- engine , 13% multi-engine, 19% ultralight , 3% helicopter and 43% glider There
18-540: Is extensive glider activity due to the presence of Miami Gliders, a glider flight school, operating out of runway 9 turf. Homestead is also the home of Skydive Miami. Elevation The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid , a mathematical model of the Earth 's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum ). The term elevation
24-486: Is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface. Elevation is not to be confused with the distance from the center of the Earth. Due to the equatorial bulge , the summits of Mount Everest and Chimborazo have, respectively,
30-579: The landscape at different scales. Tools inside the GIS allow for manipulation of data for spatial analysis or cartography. A topographical map is the main type of map used to depict elevation, often through contour lines . In a Geographic Information System (GIS), digital elevation models (DEM) are commonly used to represent the surface (topography) of a place, through a raster (grid) dataset of elevations. Digital terrain models are another way to represent terrain in GIS. USGS (United States Geologic Survey)
36-617: The largest elevation and the largest geocentric distance. In aviation, the term elevation or aerodrome elevation is defined by the ICAO as the highest point of the landing area. It is often measured in feet and can be found in approach charts of the aerodrome. It is not to be confused with terms such as the altitude or height. GIS or geographic information system is a computer system that allows for visualizing, manipulating, capturing, and storage of data with associated attributes. GIS offers better understanding of patterns and relationships of
