Which statement best describes wake turbulence considerations on final approach or takeoff/landing?

• A. To maintain safe clearances after a heavy or super aircraft to avoid wake effects.
• B. To ensure proper landing speed.
• C. To reduce noise.
• D. To increase fuel efficiency.

Answer: (A)

Wake turbulence is caused by wingtip vortices shed by heavier aircraft, and it can affect a following airplane during critical phases like final approach or takeoff/landing. Because these vortices can linger and sink into the flight path, keeping safe clearances behind a heavy or super aircraft is essential to prevent loss of control or uncommanded attitude changes. This is why the statement about maintaining safe clearances after a heavy or super to avoid wake effects is the best description: it directly addresses the risk and the required precaution in these tight, low-altitude or high-energy phases of flight. Other options touch on unrelated goals like landing speed, noise, or fuel efficiency, which are important in their own right but don’t address the wake hazard that wake turbulence presents.
