What is one advantage of an NDB over a VOR?

  1. The signal is not affected by lightning, static, or other storms in the area
  2. It gives a precise radial from the station
  3. Low or medium frequency signals are not limited by line of sight
  4. It shows the distance to the station
Show answer

Correct answer: Low or medium frequency signals are not limited by line of sight

NDB signals follow the curvature of the Earth, so they can be received regardless of altitude if the aircraft is in range.
