VHF Omnidirectional Range (VOR)

A VHF omnidirectional range (VOR) is a short-range radio navigation system that enables aircraft to determine their position and stay on course by receiving radio signals transmitted by fixed ground beacons. It provides 360 distinct magnetic radials radiating outward from the station.

Key Points

  • •Operates on VHF frequencies and provides precise magnetic track guidance via radials.
  • •Line-of-sight range is limited by the aircraft's altitude and surrounding terrain.
  • •Subject to specific errors such as scalloping and aggregate errors.

Exam Relevance

VOR tracking, position fixing, and interpreting Course Deviation Indicator (CDI) readings are core competencies for cross-country and instrument navigation.
