Content last revised: 2006/12/01

(amended 2006/12/01; no previous version)

  1. (1) Runway visibility is assessed while stationary at the runway threshold take-off point, at the taxiway holding position for the taxiway adjoining the runway threshold, or at a point adjacent to the runway threshold. 

  2. (2) When assessing runway visibility, a pilot:

    1. (a) assesses, in the runway direction, the furthest visible runway edge lights or landmarks within 10 degrees of the runway centreline that can be seen and recognized;

    2. (b) from the assessment in paragraph (a), determines the distance (in feet) based on a 200 foot runway edge light spacing or using the applicable Aerodrome Chart published in the Canada Air Pilot (CAP); and

    3. (c) immediately reports the distance assessed to ATS, if available, or to the inquiring party, as the runway visibility along the specified runway in the following format:

      "RUNWAY VISIBILITY, RUNWAY [runway number] ASSESSED AS [distance assessed] FEET AT [time] UTC", to the nearest 100 foot increment.

  3. (3) If the runway visibility varies during the assessment, the pilot reports the lowest value observed.

  4. (4) The lowest reported value is 200 feet, with lower values reported as "... LESS THAN 200 FEET ...".

  5. (5) The highest reported value is 6,000 feet, with higher values reported as "... GREATER THAN 6,000 FEET ...".
