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 ...
A VOR/DME ground station in Germany. In radio navigation, a VOR/DME is a radio beacon that combines a VHF omnidirectional range (VOR) with a distance-measuring equipment (DME). [1] The VOR allows the receiver to measure its bearing to or from the beacon, while the DME provides the slant distance between the receiver and
The basic principles of air navigation are identical to general navigation, which includes the process of planning, recording, and controlling the movement of a craft from one place to another. [ 1 ] Successful air navigation involves piloting an aircraft from place to place without getting lost, not breaking the laws applying to aircraft, or ...
A mechanical VOR display. A course deviation indicator (CDI) [1] is an avionics instrument used in aircraft navigation to determine an aircraft's lateral position in relation to a course to or from a radio navigation beacon. If the location of the aircraft is to the left of this course, the needle deflects to the right, and vice versa.
One can also use the 1 in 60 rule to approximate distance from a VOR, by flying 90 degrees to a radial and timing how long it takes to fly 10 degrees (the limit of the course deviation indicator). The time in seconds divided by 10 is roughly equal to the time in minutes from the station, at the current ground speed .
A tactical air navigation system, commonly referred to by the acronym TACAN, is a navigation system initially designed for naval aircraft to acquire moving landing platforms (i.e., ships) and later expanded for use by other military aircraft. It provides the user with bearing and distance (slant-range or hypotenuse) to a ground or ship-borne ...
The pilot can follow this course manually (much like following a VOR radial), or the autopilot can be set to follow the course. The FMS mode is normally called LNAV or Lateral Navigation for the lateral flight plan and VNAV or vertical navigation for the vertical flight plan.
Terminal Procedure with Approach Intersections. In aviation, an intersection is a virtual navigational fix that helps aircraft maintain their flight plan.It is usually defined as the intersection (in the geometrical sense) of two VOR (VHF Omnidirectional Range) radials.
