Distance Measurement


Distance measurement in aviation refers to the process of determining the distance between two points in the air or on the ground. This is a critical aspect of aviation as it is necessary for pilots to know their distance from other aircraft, terrain, and obstacles to ensure safe flight. There are several methods of distance measurement used in aviation, including GPS, radar, and visual estimation. GPS is the most accurate method of distance measurement and is commonly used in modern aircraft. Radar is also used for distance measurement, particularly in air traffic control. Visual estimation involves using landmarks or other visual cues to estimate distance, but is less accurate than GPS or radar.
