-
(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 ...".
