20-501: A gauge inside the aircraft cockpit. A radar altimeter measures altitude more directly, using the time taken for a radio signal to reflect from the surface back to the aircraft. Alternatively, Frequency Modulated Continuous-wave radar can be used. The greater the frequency shift the further the distance travelled. This method can achieve much better accuracy than the pulsed radar for the same outlay and radar altimeters that use frequency modulation are industry standard. The radar altimeter

It
40-467: Is used to help navigate the helicopter Ingenuity on its record-setting flights over the terrain of Mars by means of a downward-facing Lidar altimeter. Global Positioning System (GPS) receivers can also determine altitude by trilateration with four or more satellites . In aircraft, altitude determined using autonomous GPS is not reliable enough to supersede the pressure altimeter without using some method of augmentation . In hiking and climbing, it
50-627: Is used to measure height above ground level during landing in commercial and military aircraft. Radar altimeters are also a component of terrain avoidance warning systems, warning the pilot if the aircraft is flying too low, or if there is rising terrain ahead. Radar altimeter technology is also used in terrain-following radar allowing combat aircraft to fly at very low height above the terrain. After extensive research and experimentation, it has been shown that "phase radio-altimeters" are most suitable for ground effect vehicles , as compared to laser, isotropic or ultrasonic altimeters. Lidar technology
60-487: The 12-month period ending July 2, 2011, the airport had 24,000 general aviation aircraft operations, an average of 65 per day. At that time there were 88 aircraft based at this airport: 78.4% single- engine , 15% multi-engine, 1% jet , 3% helicopter , and 2% ultralight . It has a non-directional beacon (callsign WRLB3306 ) on AM longwave 416 kHz , which identifies itself with DJD in Morse code tones, then announces
70-473: The US Army Air Corps and General Electric tested a sonic altimeter for aircraft, which was considered more reliable and accurate than one that relied on air pressure when heavy fog or rain was present. The new altimeter used a series of high-pitched sounds like those made by a bat to measure the distance from the aircraft to the surface, which on return to the aircraft was converted to feet shown on
80-447: The name twice, followed by " automated altimeter ", and the local sea-level pressure in inches of mercury (such as "two-niner-niner-five" for 29.95). Altimeter 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 1931,

100-856: Was previously 47A when it was known as the Cherokee County Airport , prior to improvements made in the 2010s. A redevelopment project currently underway includes an already completed 10,000-square-foot (930 m ) terminal; the ongoing lengthening of the runway from its previous 3,414 feet (1,041 m) to 5,000 feet (1,524 m); a new parallel taxiway ; instrument landing equipment; and new hangars . The new facilities will accommodate 200 hangared corporate aircraft and provide 100 tie-downs for smaller aircraft. Cherokee County Airport covers an area of 160 acres (65 ha) at an elevation of 1,219 feet (372 m) above mean sea level . It has one runway designated 5/23 with an asphalt surface measuring 5,002 by 75 feet (1,525 × 23 m). For
