Definition#
Drag is the aerodynamic force that opposes an aircraft's forward motion through the air. Total drag is the sum of parasite drag (form, skin friction, interference) and induced drag (byproduct of lift).
Why It Matters Operationally#
Drag determines fuel consumption, cruise speed, climb rate, and range. The speed at which total drag is minimized (L/DMAX) yields maximum range and endurance.
