VOR range details
 

Hi Folks

I have tried searching for VOR details but no luck yet.
I would like to know where I can get information on VORand ADF ranges times of ops (NOTAMS) etc.

I am doing some nav exercises and VOR range would be handy as I don't want to bump into any airspace that I shouldn't be in. Perhaps I shouldn't fly too close but I want to be acccurate in my flying anyway.

Help, as always, appreciated.

VOR uses the VHF band, which is line of sight, so it isn't different for each different VOR The theoretical distance (in NM) is 1.25 times the square root of you aircraft altitude in feet. In Australia they publish a table of distances and height for planning.

UK Navaids are included in the AIP Enroute section 4

DOC is designated operational coverage, above which interference may be possible.

Thanks guys. SJ, I like the calculation guide and CB, there is so much on the AIS site, it is sometimes quicker to ask where to look.

In this corner of the planet, we publish range - specified as "rated coverage" for NDB and Locators only. Up to now, we've said next to nothing about LoS-type navaids. Thankfully, that is finally being addressed in the rewrite of our rules and, for enroute planning purposes (and drawing up enroute tolerance areas for a Lowest Safe Altitude), the range of a VOR will officially be assumed to be 60NM.

Don't think that'll help you very much rex, but thought I'd throw it in anyway...

VOR Line of sight:

Distance in miles = 1.25 x square root of (transmitter height in feet + reciever height in feet)

However I would only use this as a guide. If it is situated in the middle of a valley - the distance you receive it at will decrease significantly :D :D

Hope this helps
