Background Discussions between Transport Canada and the Northwest Territories Department of Transportation determined that there is a need for more consistent procedures regarding RSC reporting for gravel runways. The concern centred around the need to report the type of base structure that the aircraft tires will encounter as well as the need for a description of any overlying winter contaminants. The reporting of surface conditions on a gravel runway is more difficult than it is for a paved runway. In the case of gravel runways, it is impossible to remove all the winter contaminants from the gravel surface. In many northern sites, the common practice is to prepare a solid snow-compacted base on top of the gravel whereby the compacted snow becomes the operational surface for winter operations.
