Frequency Band
VORs in Canada operate on assigned channels spaced at 0.05 MHz (50 kHz) increments within the frequency range 112.0 to 117.95 MHz.
The implication for users is that, in airspace serviced solely by VOR, aircraft equipped with older VOR receivers which cannot be tuned to two decimal places (e.g. 115.25 MHz) may not be able to operate under instrument flight rules (IFR). Of course, area navigation (RNAV), where approved for use, may enable operation under IFR.
Receivers with integrated distance measuring equipment (DME) (i.e. VOR/DME receivers) normally select the associated DME “Y” channel automatically, while stand-alone DME receivers display the “X” and “Y” channels separately.
