Canadian VOR alignment tolerance is maintained at how many degrees?

• A. 3 degrees
• B. 1 degree
• C. 5 degrees
• D. 2 degrees

Answer: (A)

VOR alignment tolerance is the maximum permissible error in the azimuth reference of a VOR ground station during calibration. In Canada, this tolerance is three degrees, meaning the published VOR radials must fall within ±3 degrees of the intended azimuth when the facility is aligned. This keeps navigation guidance reliable for enroute tracking and approaches, because the VOR’s bearing indications are used to fly courses and intercept radials. If the alignment drifted beyond three degrees, the indicated bearings could systematically lead you off course. Smaller tolerances would be more demanding to maintain, while a larger tolerance, like five degrees, would reduce accuracy beyond what standard navigation requires.
