aerodynamicsFAA-published sample question (AGI, Aug 2021)
At a constant velocity in airflow, a high aspect ratio wing will have (in comparison with a low aspect ratio wing)
A
increased drag, especially at a low angle of attack.
B
decreased drag, especially at a high angle of attack.✓ Correct Answer
C
increased drag, especially at a high angle of attack.
Explanation
A high aspect ratio wing produces weaker wingtip vortices and therefore less induced drag than a low aspect ratio wing at the same lift, and induced drag matters most at high angles of attack (PHAK Chapter 5). So it has less drag, especially at high angle of attack.
