    There’s no real need for a rule of thumb or any calculation – VORs have a “standard service volume” that ensures* signal reception within that range.Typically at light aircraft altitudes it’s 40nm as long as you’re greater than 1000 feet above the VOR itself.

    See the Aeronautical Information Manual for more information:
    http://www.faa.gov/air_traffic/publications/ATpubs/AIM/aim0101.html#ncG212JACK

    * Not all radials, however, can be received this far from a particular VOR depending on local terrain and obstructions (buildings). A given VOR may have service restrictions – for example, “radials 360-060 unusable beyond 20nm”.

    Also, radials may be used at far greater than their normal range – you will often see airways with distances of greater than 80 nm between them. In this case the radials are specifically flight checked for signal integrity before being published.
