Division IV – Airport Winter Maintenance
The objectives of airport winter maintenance planning are to minimize the effects of winter conditions and to establish requirements and procedures pursuant to the Canadian Aviation Regulations to prevent or eliminate hazardous conditions in order to maintain safe aircraft operations.
In this Division,
“cleared width” means the narrowest portion of the runway width that has been cleared of loose contaminants; (largeur dégagée)
“compacted snow” means snow that has been compacted into a solid mass such that aeroplane tires, at operating pressures and loadings, will run on the surface without significant further compaction or rutting of the surface; (neige durcie)
“dry” means a surface condition that is free of visible moisture, and has no observed contaminants; (sèche)
“frost” means ice crystals formed from airborne moisture on a surface whose temperature is below freezing. Frost differs from ice in that the frost crystals grow independently and therefore have a more granular texture; (givre)
Below freezing refers to air temperature equal to or less than the freezing point of water (0 degree Celsius).
“percent coverage of contaminant” means the estimated amount of contaminant present on the surface of the runway and reported as a percentage (%) of the assessed surface; (pourcentage de couverture de contaminant)
For example if a runway is totally covered with 0.5 inches of a contaminant such as dry snow, it is reported as 100% 0.5 inches dry snow. If half of the runway is covered with 0.5 inches of dry snow and half of the runway is dry, it is reported as: 50% 0.5 inches dry snow.
“Runway Surface Condition” or “RSC” means the portion of the AMSCR which reports the surface condition of the runway; (état de la surface de la piste ou RSC)
“significant change” means, with respect to runway surface condition includes but is not limited to: changes in type of contaminant, such as from dry snow to wet snow; measurable changes in depth of contaminant; following the application or removal of sand or chemicals; following snow removal or sweeping; changes in conditions caused by rapid increases or decreases in temperature; (changement significatif)
“standing water” means water of depth greater than 3 mm (1/8 inch); (eau stagnante)
“wet” means a surface condition where there is any visible dampness or water up to and including 3 mm (1/8 inch) deep; (mouillée)
“wet ice” means ice with water on top of it or ice that is melting; (glace mouillée)
“windrow” means a ridge of material, such as snow or gravel, created by airside maintenance equipment. (andain)
