Question

Which among the following statements is false about a very high frequency omnidirectional range (VOR)?

(a) VOR is a radio navigation system for aircrafts

(b) The frequency range of VOR is 108.00 to 117.95 MHz

(c) VOR is intolerant of diffraction

(d) VOR signals show more accuracy than nondirectional radio beacon

The question was asked during an interview.

I'd like to ask this question from Next Generation Wireless Network in portion Next Generation Wireless Network of Cognitive Radio

Answer 1

Right choice is (c) VOR is intolerant of diffraction

For explanation I would say: Very high frequency omnidirectional range is a radio navigation system incorporated in aircrafts to stay on route with the help of radio signals transmitted by a network of ground radio beacons. A prominent feature of VOR is that the bearing from the station to the aircraft is unaffected by wind and orientation of the aircraft.
