The wake categories of aircraft are designated as which of the following?

• A. Categories A through I
• B. Categories A-D
• C. Alpha through Delta
• D. Light through heavy

Answer: (A)

Wake turbulence separation relies on a structured set of categories that classify aircraft by the strength of the wake they create. The official system uses nine distinct categories, labeled in order from the smallest to the largest, to capture the wide range of potential wake effects. Because there are nine categories, this designation best matches the real framework used in ATC procedures, enabling precise spacing based on the leading aircraft’s wake potential.

The other options don’t fit because they suggest too few categories (A through D), use nonstandard labels (Alpha through Delta), or describe the aircraft in vague size terms (Light through heavy) that don’t reflect the formal nine-category scheme used for wake separation.
