Definition#
Chord line is the imaginary straight line drawn from the leading edge to the trailing edge of an airfoil. It serves as the geometric reference for defining angle of attack.
Why It Matters Operationally#
The chord line is a foundational concept in aerodynamics. Angle of attack is measured between the chord line and the relative wind, making it essential for understanding lift, stall, and performance.
