O-320-D Power Spreadsheet Available

I created an O-320-D power spreadsheet, just in case anyone is interested. It replicates the Lycoming power charts for the O-320-B and -D engines, except for the O-320-B2D, -B2E and -D2J. It is only valid if the mixture is set for best power.

I ran a few test cases against the paper power chart, and it seems to match OK. I'd like to find a power table from the POH of some type-certificated aircraft to check it against, but I haven't found one yet. Can anyone point me to any type certificated aircraft with constant speed props that used one of these engines? Fixed pitch power charts are useless for this purpose, as they don't provide the MP.

Kevin,
At least on my copy, lines 11 -12 and 21-120 don't show up in the spreadsheet that I can see. These contain the equations that you used to generate the hp numbers.

Unprotect the sheet and then unhide the rows. Lots of info there.
