1.	Is down wash is change in direction of lift?(a) True(b) FalseThis question was posed to me during an interview.This intriguing question comes from Downwash and Induced Drag in section Flow over Airfoils over Finite Wing of Aerodynamics
Answer» The correct ANSWER is (a) True Best explanation: Down wash is the change in DIRECTION of air deflected by the aerodynamic action of an airfoil, wing, or helicopter rotor blade in motion, as part of the PROCESS of producing lift. When the RELATIVE wind moves from nose to down side of the wing which causes change in direction of air and PRODUCE lift.
