frequency allocation 100/50khz spacing

[Paulo]

Hi to all

to this I am embarrassed, but i have a problem working out frequncy spacing, I know this should be very simple "sums" but I have a block on this.

in the introdution to the VOR chapter 5 it states that 108.2 and 113.35Mhz would be VOR frequencies with 50khz spacing and 108.1 would not

help please, sorry to be such a dumbo

Cheers Paulo

The VOR frequency range is 108.00 - 117.95 MHz.

A part of that is shared with ILS.

This is the range from 108.00 - 112.00 MHz.

Frequencies allocated to ILS use ODD 100 kHz frequencies, i.e. the digit after the decimal, i.e.

108.10, 108.15, 108.30, 108.35, etc. all the way up to 111.95 MHz.

Frequencies allocated to VOR use EVEN 100 kHz frequencies, i.e.

108.20, 108.25, 108.40, 108.45, up to 112.00 MHz.

Anything above 112.00 is a VOR frequency.
