Induced drag is caused by the production of lift.

Induced drag is caused by the production of lift.

• A. True
• B. Not Related
• C. Depends on airspeed
• D. False

Answer: (A)

Induced drag comes from the way a wing generates lift. When a wing produces lift, air must be redirected downward to create the required pressure difference. This downward deflection creates downwash and wingtip vortices, which consume energy and show up as resistance to forward motion—drag. So, the production of lift inherently brings about induced drag, making the statement true. The amount of induced drag changes with lift demand and airspeed (it typically decreases at higher speeds for the same lift), but its cause is the act of generating lift itself.
