- Definição1
- A type of electronic navigation equipment in which the instrument in the cockpit indentifies the radial, or line from the VOR station measured in degrees clockwise from magnetic north, along which the aircraft is located. VOR is a phase-comparison system in which two signals transmitted simultaneously from a ground station are in phase only when they are received at a location directly magnetic north of the station. At a location magnetic east of the station, they are 90°out of phase. At magnetic south, they are 180° out of phase, and west of the station, they are 270° out of the phase. The pilot selects on the omni bearing selector (OBS) the radial on which he wants to fly, and the needle of the course deviation indicator (CDI) centers when the aircraft is on the radial. If the aircraft moves off the radial, the needle moves away from center to show the pilot which direction to turn the aircraft to the radial. The indictor for the VOR is often also used as the localizer indicator.
