Density Altitude Equation on HP 35s

[Geoff Quickfall]

Yep, must add that to my aviation suite. Strictly for interest as the takeoff and landing data on the b777 is computed on board.

But leaving Bogata, altitude of airport is 8000 feet on a hot day (40'C) with a low pressure 29.80 it would be interesting to see what the density altitude is. Also comparing these answers to my circular JEPP cr3 which has the log curve built in to the display.

Thanks, but what are those brackets things (((()))))?
