DVOR (Doppler VOR) ground station, collocated with DME. On-board VOR display with CDI MCT DVOR, Manchester Airport, United Kingdom.. Very High Frequency Omnidirectional Range Station (VOR) [1] is a type of short-range VHF radio navigation system for aircraft, enabling aircraft with a VOR receiver to determine the azimuth (also radial), referenced to magnetic north, between the aircraft to/from ...
Separation can also apply to terrain, obstacles, and controlled airspace, wherein an aircraft must stay at a minimum distance from a block of airspace; as an example, all aircraft must be approved by the controller who "owns" the airspace before the aircraft is approved to enter that sector.
In 1958 the standard vertical separation of aircraft in controlled airspace was set at 1,000 feet from ground level or sea level to flight level 290, and at 2,000 feet above flight level 290. [3] The larger minimum separation at higher altitudes was necessary because the accuracy of altimeters, used to determine altitude by measuring air ...
In the United States, airways [1] or air routes are defined by the Federal Aviation Administration (FAA) in two ways: "VOR Federal airways and Low/Medium Frequency (L/MF) (Colored) Federal airways" [2] These are designated routes which aeroplanes fly to aid in navigation and help with separation to avoid accidents.
In the United States, Victor airways are designated by the FAA in FAA Order JO 7400.11. [2] They are available for flight up to, but not including, 18,000ft MSL (above mean sea level) [3] under either instrument flight rules (IFR) or visual flight rules (VFR). Victor airways have minimum (and possibly maximum) altitudes for IFR operations ...
An en-route (also known as en route [1] or enroute [2]) chart provides detailed information useful for instrument flight, including information on radionavigation aids (navaids) such as VORs and NDBs, navigational fixes (waypoints and intersections), standard airways, airport locations, minimum altitudes, and so on.
Congress ordered the Federal Aviation Administration to establish minimum dimensions for airplane seats within a year when the agency's funding was renewed in October 2018. The FAA has yet to comply.
The VOR minimum operational network and NextGen distance measuring equipment (DME) will provide navigation resiliency. [61] The NAS needs at least 126 new DME stations for maximum benefits, and the FAA will replace 50 stations with limited performance to support en route flights across the nation and terminal traffic at 62 busy locations.
