BGBW is not approved with the OPS SPECS/OM Part C of a couple of airlines I know. First due to the simple fact that the approach is a nightmare (with mins just like VFR mins and high mountains around it - when adding your alternate mins you have to have very good conditions), second because of rather limiting opening hours.. .True Greenland is somewhat limiting, but I usually prefer to use BGSF.. .. .Cheers. .fcit
