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.

P.S.: You have sauna experience? At altitude ? In ski holidays?
Calculate the corresponding density altitude! I know why I am yawning in
there. ;-)

Fun! ...I thought so anyway.

900 ft .....Elevation
110 F ....Temp
29.92 ....Barometer guess
90% ......Humidity

5,282 ft .....@ the Y.M.C.A.

(What?? 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.

900 is where you start.
