How Airplanes Fly: The Complete Guide

The science of flight

Flight is made possible by four fundamental forces acting on an aircraft: lift, weight, thrust, and drag.

Lift, thrust, and drag

Lift is generated by the wings as air flows over their curved surface, creating a pressure difference. Thrust comes from the engines, propelling the aircraft forward.

Aircraft components

Every commercial aircraft relies on a combination of wings, control surfaces, and engines working together to achieve controlled flight.
