AIC 36/08 outlines NavCanadas latest decommissioning project.

NAV CANADA, the country’s provider of civil air navigation services, recently evaluated the requirement for very high frequency omnidirectional range (VOR) receiver test facilities (VOT) in Canada.

The review concluded that VOT sites are underutilized and no longer required. This fact is partly because of the increased use of global navigation satellite system (GNSS) for primary navigation and partly because many VOR receivers are equipped with an internal self-test function.

Accordingly, VOT sites will be decommissioned, starting in November 2008. It is expected that decommissioning all the current VOT sites will take several years.

Personally, I’ve never used one before. Does this mean that they will be removing the VOT related questions from the PPL/CPL written?

They are requesting users submit their comments about the decommissioning schedule.
