Washout
Definition
A design feature where the wing is twisted so the angle of incidence decreases from root to tip. This ensures the wing root stalls before the tip, maintaining aileron effectiveness during stalls.
Why Washout Matters for Pilots
Understanding Washout 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 Washout 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 Washout in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
