What a private pilot must know — authored from the FAA’s own public-domain handbooks. Aerodynamics that answer real questions (the four forces, angle of attack and stalls, load factor in turns, ground effect), aircraft systems and instruments (pitot-static and gyroscopic errors included), airspace classes and their entry and weather minimums, sectional charts, airport operations and markings, radio procedures and light-gun signals, weight and balance, performance and density altitude, and aeromedical factors. Every explanation teaches the why, names the classic misconception, and leaves a rule of thumb pilots actually use. Original questions from public FAA materials — never actual test bank items. Independent study practice, not affiliated with the FAA; not flight instruction — always defer to your CFI and current official publications.
