DA Calculator

[pmanton]

Have any of you clever computer literate people ever made a DA calculator with Excel?

I'd love to get one but I'm not clever enough to make it work.

I recently moved to an airpark in Arizona at 1600 foot elevation. In the "cool" of the morning DA can approach 5000'.

Anything I try with Excel turns out real ugly.

It's all laid out for you to build your own spreadsheet.

Understand that it does not include humidity as presented. Adjust the standard lapse rate to account for humidity.
