Thule's white runways
On page 5 of Canada's best written weather book for pilots (ahem), it is mentioned, "the asphalt runways in Thule, Greenland are painted white to enhance albedo and prevent heating of the permafrost beneath the surface." The topic of unique airports came up while flying over Greenland after we almost diverted to Moscow on a recent New Delhi to Toronto flight. My F/O air dropped this pic to me. (It turns out this same pic is on the internet). When looking at the Jeppesen approach charts there is no mention of the runways being white. Something a pilot should know when breaking out from an ILS approach and seeing a white runway. Think slippery.
Thule is so far north, the runway headings are in True. It's just short of 10,000 feet long.
