aerodynamicsFAA-published sample question (ATS, Aug 2021)
What flight condition should be expected when an aircraft leaves ground effect?
A
A decrease in parasite drag permitting a lower angle of attack.
B
An increase in dynamic stability.
C
An increase in induced drag requiring a higher angle of attack.✓ Correct Answer
Explanation
PHAK Chapter 5 explains that leaving ground effect restores the full wingtip vortices and downwash, so induced drag increases and a higher angle of attack is needed for the same lift. Parasite drag is not reduced, and stability does not increase.
