Parasite Drag
Definition
Drag not associated with lift production, including form drag from the aircraft shape, skin friction drag from air moving over surfaces, and interference drag where components meet. Parasite drag increases with the square of airspeed.
Why Parasite Drag Matters for Pilots
Understanding Parasite Drag 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 Parasite Drag 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 Parasite Drag in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
