Practice question

How many possible radials can aircraft fly toward or away from a VOR?

  1. 180
  2. 360
  3. 270
  4. 90

Answer: B — 360

The correct answer is based on the functioning of VOR (VHF Omnidirectional Range) stations, which provide navigational guidance to aircraft. A VOR station radiates signals in all directions, creating a 360-degree coverage area. This means that an aircraft can fly towards or away from the VOR along different radial paths. Each radial represents a specific degree on the compass that relates to the VOR's position. Because there are 360 degrees in a full circle, there are, therefore, 360 possible radials that an aircraft can follow. These radials allow pilots to navigate effectively by aligning their aircraft with the desired directional path in relation to the VOR. This is essential for both departure and arrival procedures, as well as for en route navigation.
