Your right I was having too much fun so apologies as I have obviously upset you.
Toronto is one example of a large airport with a VOT
If you wan't to know more just search on VOT
Yes I know that we don't do this in the UK and yes a UK IR pilot would not necessarily know about this.
If you are flying big jets internationally I don't think you need to worry about this but if any of your aircraft have VOR;s fitted and have an N on the tail then you might wan't to know about this (as well as the requirement for a full pitot/static test every 24 month, now that is thorough).
