Re: Altitude vs. Barometric pressure
den alt needs temp, pressure, dew point and field elevation. You get that from a weather
station. Kestrel or any other. A lot of weather stations don't give you DA. The model I
use does. But if you enter a load in FTE with den alt that is the way it has to be used.
Always good to have backup in the field. Especially when it weighs and costs nothing.
I guess I could add, the program uses dew point because it is designed for flying, so
icing and carb heat require knowing the dew point anyway.
