July issue of AOPA pilot considered density altitude a major topic. I
have looked a bit around on the net and found formulas to compute exact density altitude from indicated altitude and weather data. (http://wahiduddin.net/calc/density_altitude.htm) Well, I implemented these formulas into a Google gadget. You can find it at http://airspace-v.com/ggadgets You can add it to Google, use it on http://www.airspace-v.com, or put it on your own web site. Of course, this also holds for other gadgets listed on this page. There is at least one more gadget interesting for flight preparation: The wind calculator to compute heading and flight time from TAS, course, wind speed and wind direction. Different units of measurement are supported. You may even mix them. virtuPIC P.S.: You have sauna experience? At altitude ? In ski holidays? Calculate the corresponding density altitude! I know why I am yawning in there. ;-) -- Airspace V - international hangar flying! http://www.airspace-v.com |

That's where the steam room is. g) Where does elevation come into it? temp, pressure and humidity defines the density of the air ( 1.083kg/m3 in this case) , which is then compared to the density of the standard atmosphere, which in my calcs gives 4140 ft as the density altitude. terry |

900 is where you start.
