Definition of Slant Range
Slant range is the term used to refer to the distance between an aircraft’s antenna and a ground station. This is measured horizontally, taking into account the line-of-sight transmission of the DME signal. Slant range is a critical factor in aviation as it is used to accurately determine an aircraft’s position relative to a ground station or other navigational aid.
The slant range is calculated by measuring the time it takes for a signal to travel from the aircraft to the ground station, and back again. This measurement is then used to determine the distance between the two points, taking into account the speed of light and other environmental factors such as temperature, pressure, and humidity.
Slant range is essential for accurate navigation and is used in a range of applications, including instrument landing systems, air traffic control, and military operations. The accuracy of slant range measurements can be affected by a range of factors, including interference from other signals and weather conditions.
Overall, slant range is a critical concept in aviation and is used to ensure the safety and efficiency of air travel. Accurate measurements of slant range are essential for accurate navigation and communication between aircraft and ground stations.
