Aeronautics: Why Airplanes Stay in the Sky and How Flight Works

Series "In Twelve Evenings" Book 4

What Do I Already Know About This?

Vita Harwood

How can an airplane weighing tens or even hundreds of tons stay in the sky? What really creates lift? Why can a wing stall, why does an airplane bank to turn, and what does the autopilot actually do once a route has been loaded into the computer?

Aeronautics: Why Airplanes Stay in the Sky and How Flight Works invites readers to understand modern aviation in twelve evenings. The book begins with humanity's earliest attempts to fly, then builds the airplane as one connected system: atmosphere and aerodynamics, wings and flight controls, piston and jet engines, structural strength, hydraulics and electricity, navigation, weather, safety, and the future of flight.

Readers discover why the familiar equal-transit-time explanation of lift is wrong, what a stall really is, how fly-by-wire, GNSS, FMS, and inertial navigation work, why an airplane can still glide after engine failure, and how engineers design for turbulence, icing, system failures, and repeated loads.

No college-level math is required. Formulas appear only when they make the physics easier to see. Every lesson includes key terms, a quiz, a simple home experiment, and a Flight Log prompt. The book closes with 120 explained answers, a complete glossary, verified resources, and suggestions for what to read and watch next.

If you have ever looked at an airliner and thought, "How can that possibly work?", this book is your invitation to find out.
