Air navigation and communication with air traffic control (ATC) is mostly based on the use of navigational beacons and airways. This allowed less experienced users to achieve the same results as highly trained celestial navigators and eventually decreased the need for professional navigators. Most ADF radio receivers signals are in the frequency spectrum of 190 kHz to 1750 kHz, which includes LF and MF navigation facilities, and the AM commercial broadcast stations. When war broke out, new military equipment revolutionized air navigation. Each system of radio navigation uses time in a slightly different way and each requires its own type of navigational charting.īy World War II, a web of air navigation radio stations and beacons connected by “airways” began to cover the globe. ![]() Marker beacons and high intensity runways lights may. ![]() The localiser (LOC)provides azimuth guidance, while the glideslope (GS) defines the correct vertical descent profile. The invention of timekeeping technologies, such as the crystal oscillator, led to a new era of systems that could fix position accurately and were easier to use. An Instrument Landing System is a precision runway approach aid employing two radio beams to provide pilots with vertical and horizontal guidance during the landing approach. ![]() Radio navigation became the most important air navigation technology.īefore World War II, radio navigation could only provide a course or a bearing to a station. An aeronautical light beacon is a visual NAVAID displaying flashes of white and/or colored light to indicate the location of an airport, a heliport, a landmark. ![]()
