Downwash
Definition
The downward deflection of air behind a lifting surface. Downwash reduces the effective angle of attack of the tail, affects stability, and contributes to induced drag.
Why Downwash Matters for Pilots
Understanding Downwash 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 Downwash 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 Downwash in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
