EHSI Wind Indicator Question

Recommended Posts

Guest

All,What, exactly, is the wind arrow telling me? Is this surface wind? Last night, at FL350, I got indicated winds on the EHSI varying from calm to 7 or 8 knots, while a check of the weather overview window showed winds at varying times during my flight at 27 to 42 knots. On final into KPHX, the indicated winds were exactly what ABQ_CTR said they'd be.It's a handy device, to be sure, because it gives good gouge on a crosswind approach, but shouldn't it provide winds where the airplane is? Why didn't I see the 35+ knot crosswinds at FL350?Kurt KalbfleischAmerica West Virtual(Vive la Rolls)

Kurt-the wind arrow is telling you the Current Wind Heading and Speed at the aircraft LOCATION, in 3-Dimensional space. That is, at its' current latitude, longitude and ALTITUDE.If it's not working properly, (which I've never noticed - I think it works fine, to be honest), you should address Rich Harvey, as the information is coming straight from the Fly! SDK usingAPIGetWindSpeed() andAPIGetWindHeading()Cheers,
