- Definição3
- A short-range VHF (very high frequency) radio navigation system that operates within the 108.00 to 117.95 MHz frequency band and has a power output necessary to provide coverage within an assigned operational service volume. The system is subject to line-of-sight restrictions, and the range varies proportionally to the altitude of the receiving equipment.

- Nota adicional1
- 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.
- Nota adicional2
- The only positive method of identifying a VOR is by its Morse code identification or by the recorded automatic voice identification, which is always indicated by use of the wors VOR following the range's name.
- Nota adicional3
- Most VORs are equipped for voice transmission on the VOR frequency. VORs without voice capability are indicated by including the letter W (without voice) in the class designator (VORW).
