Lift
Definition
The aerodynamic force perpendicular to the relative wind generated by an airfoil. Lift is produced by the pressure differential between the upper and lower surfaces of a wing as air flows over it.
Why Lift Matters for Pilots
Understanding Lift is critical for passing the FAA Private Pilot Knowledge Test and performing safely in flight. Aerodynamics questions make up a significant portion of both written exams and oral checkrides. Pilots who grasp concepts like Lift can make better decisions during all phases of flight, from takeoff to landing.
Exam Tip
This concept is commonly tested in aerodynamics-related questions on FAA and EASA exams. Make sure you can explain Lift in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
