Module 11. Aeroplane aerodynamics, structures and systems

111.1 MHz is

  • a VOR frequency.
  • a HF frequency.
  • an ILS frequency.

Explanation

The ILS localiser uses the odd-tenths channels in the 108.10-111.95 MHz portion of the VHF navigation band. 111.1 MHz fits the localiser channelling pattern, making it an ILS frequency rather than a VOR or HF frequency (HF lies far below in the 3-30 MHz range).

IT has even hundreds... S-o why îs not a VOR freq?

the right answer is ILS and to be precise the ILS localizer which is 108-112 Mhz and the number above it within it.
