Principles of Flight

EASA ATPL Ground School

Aerodynamic theory independent of any aircraft: atmosphere and airspeeds, sections and finite wings, lift and drag, the boundary layer, stalling, high-lift devices, primary and secondary controls, static and dynamic stability, compressibility and shockwaves, propellers, structural loads and limitations, and windshear.
