Standard 622.131 - Pilot Assessment of Runway Visibility - Canadian Aviation Regulations (CARs)

(amended 2006/12/01)

  • (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) When assessing runway visibility, a pilot:

    • (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;

    • (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

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

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

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