{Origin of VOR}}

The VOR is a very high frequency(VHF)NAVAID that is extensively used in instrument flying. Its full name is the very high frequency omni-directional radio range. The VOR was developed in U.S. during the late 1940s,and was adopted by the International Civil aviation Organisation(ICAO) as the standard short-range radio navigation aid in 1960.When introduced,it offered an immediate improvement over previously existing aids such us ADF/NDB combination, most of which operated in lower frequency bands than the VOR and suffered significant limitations such as night effect,mountain reflections and interference from electrical storms.
