Question

VOR stations depend on __________

(a) Line of approach

(b) Line of sight

(c) Line of descent

(d) Line of attack

This question was posed to me in unit test.

I'd like to ask this question from Aviation Communication Systems in section Aviation Communication Systems of Aircraft Maintenance

Answer 1

Right answer is (b) Line of sight

To elaborate: VOR stations are dependent on line of sight. They heavily rely on it as an unclear line of sight means the observer will not be able to see the transmitting antenna clearly and thus an appropriate signal will not be received.
