Chord
Definition
The straight-line distance from the leading edge to the trailing edge of an airfoil. The mean aerodynamic chord (MAC) is used as a reference for center of gravity calculations.
Why Chord Matters for Pilots
Understanding Chord 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 Chord 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 Chord in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
