The Bootstrap Approach to Aircraft Performance
(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.
