how much is Narsasuaq used as enroute alternate/ emg field and how realistic is this. Anyone?
Speaking from the experience of multiple landings at Narssarssuaq (BGBW) I would not recommend its use as a diversion for a heavy jet except in the most dire circumstances. Located at the bottom of a glacier, rugged topography surrounding and with the fjord open to the ocean, the weather is just too unpredictable. And, don't even talk about the turbulence associated with surface winds over 20 knots.
