AirVenture2010 and 2011 Presentations,
Power and Drag Workbooks for several airplanes plus reference documents:

If you come to this page and view any of the materials, please let me know. I don't have a "hit counter". Thanks.

Workbooks (These all use "zero thrust" except the RV-7A)

Update: Third method for "LocatingX" page in spreadsheet. The Vms speed can be found by establishing a partial power glide where the power is somewhat below what would be needed for level flight. At this power setting, the airspeed that produces the minimum sink as measured by GPS is the Vms. Verification can be done as already described.

CAUTION: There is an error in the older spreadsheets that makes TAS computations wrong above 10,000. I will fix it soon.
