VOR information received on the plane gives the pilot radial information during flight. The VOR station produces 360 linear lines called radial at one degree intervals around itself. ![]() DME – Distance Measuring Equipment VOR (VHF Omni-Directional Range) It does not provide direction information, only the distance to the station is obtained. It works with the “pulse waves” system sent from the ground station. NDB – Non Directional Beacon DME (Distance Measurement Equipment) Aircraft equipped with the appropriate equipment determine their air conditions according to these signals. Ground radio transmitter station that broadcasts at low or medium frequencies, which is not very sensitive, in order to find a heading. Let us explain the devices on the ground in order. Radars, on the other hand, have different features, especially determining the location/distance in the air. Landing facilitators are ILSand MLS and visual aids (such as runway lights). Direction/distance purpose devices located on the ground are NDB, DME, VOR. During navigation, devices installed on aircraft receive position, distance, heading, height, all information from the devices (navigation aids) on the ground and/or satellite. It includes planning, takeoff, climb, cruize flight, descent and landing stages. Navigation in aviation is the process of taking the plane from one place to another with planning, position, direction, time and distance solutions. Let’s first make a brief definition of navigation. With new technology aircraft and systems, you can fly and land/take off even in completely overcast weather and difficult meteorological conditions. Aircraft position in the air is determined with radars and satellite-based systems (navigation aids). Today, there are very advanced direction finding, distance determination, approach/landing devices, systems and facilities. A compass and a map that is doubtfull how detailed it is were the only materials to aid the flight. Have you ever wondered how aircrafts (planes, helicopters…) find their way during flight? You can imagine that in the early years of aviation, pilots were more on their own with very limited aids in the air. ![]()
