VHF Omnidirectional Range (VOR)

Question 1

All directions associated with a VOR station are related to:

Answer 1

Magnetic north

Question 2

The rate that the transmitted VOR variable signal rotates is equivalent to how many revolutions per second?

Answer 2

30

Question 3

What is the frequency range of the ground-based Very-high-frequency Omnidirectional Range (VOR) stations used fo aircraft navigation?

Answer 3

108.00 MHz to 117.95 MHz

Question 4

Lines drawn from the VOR station in a particular magnetic direction are:

Answer 4

Radials.

Question 5

The amplitude modulated variable phase signal and the frequency modulated reference phase signal of a Very-high-frequency Omnidirectional Range (VOR) station used for aircraft navigation are synchronized so that both signals are in phase with each other at _____ of the VOR station.

Answer 5

360 degrees North, magnetic bearing position.

Question 6

What is the main underlying operating principle of the Very-high-frequency Omnidirectional Range (VOR) aircraft navigational system?

Answer 6

A phase difference between two AC voltages may be used to determine an aircraft’s azimuth position in relation to a selected VOR station.
