The Bootstrap Approach to Aircraft Performance by John T. Lowry
(Part One — Fixed-Pitch Propeller Airplanes)
You say your airplane's POH doesn't have some performance numbers you
need? Or, because of airframe or powerplant modifications, your
factory-original POH performance section is out of date? Or perhaps you
need numbers for your one-of-a-kind homebuilt? Don't despair ... and
don't guess! Now there's an easy way to calculate accurate light
aircraft V-speeds, rates and angles of climb, thrust, drag, and much
more. Aviation physicist and private pilot John T. Lowry shows you how.

The Bootstrap Approach to Aircraft Performance by John T. Lowry
(Part Two — Constant-Speed Propeller Airplanes)
Calculating performance numbers for an airplane equipped with a
constant-speed propeller requires a different bootstrap model than was
used with fixed-pitch props. In this promised follow-up to his earlier
article on performance of fixed-pitch propeller aircraft, aviation
physicist John T. Lowry offers a downloadable spreadsheet plus some
guidance on how to use it to calculate key V-speeds and performance
numbers at any given combination of loading and atmospheric conditions.

The Bootstrap Approach to Aircraft Performance by John T. Lowry
(Part Three — Maneuvering)
Okay, bootstrappers ... time to cut loose and have some fun! In the
first two bootstrap articles by aviation physicist John T. Lowry — Part
One on basics for fixed-pitch aircraft, Part Two on constant-speed-prop
aircraft — the airplane was kept at full throttle, or perhaps gliding,
and always wings level. But eagles don't soar wings-level. (Then again,
neither do buzzards.) This article takes the airplane, still at full
throttle, and lets it bank and turn. Since bootstrap calculations are
easy and realistic, we'll be able to calculate interesting turn
performance numbers and bring up some new concepts. To do that, two
downloadable Excel spreadsheets are included: banks.xls, on geometric
aspects of level turns, and bootstp3.xls, details on maneuvering a
fixed-pitch airplane.
