If you’re not careful and select an inappropriate runway for landing, a tailwind is indicated as a negative headwind; not sure how real tools do it, but it would be more obvious if tailwind was indicated (and perhaps highlighted when it exceeds e.g. 5 knots).
RWY 22 in use for arrivals and departures with tailwind components up to 4 kts. Otherwise, RWY 04 will be used.
Not sure it corresponds to IRL procedure or not, but it makes sense (no mountains in the way of a runway 22 landing), and I guess other airports might have similar considerations driving the choice of takeoff/landing runway. So I figure highlighting small tailwinds in too obvious a manner (like in red) might not be best.
