I'm flying to KTM regularly, in a Heavy. In fact, I took off from there a few hours before this accident. I can not, for the life of me, understand why anyone would circle to Rwy 20 unless the tailwind component on 02 is absolutely prohibitive. 7 knots tailwind should never be, for a Q400. I'll prefer 10 knots tailwind for Rwy 02, even in a heavy, any day of the week.
