What are the wake categories of aircraft?

• A. CAT I thru III
• B. Categories A thru I
• C. Small, Large, Heavy and Super
• D. General aviation, military, air taxi and air carrier

Answer: (B)

Wake categories are used to determine separation by grouping aircraft into performance-based levels so ATC can apply appropriate wake turbulence spacing. In this material, those categories are labeled with letters from A through I, giving nine distinct groups. This alphabetic scheme is how the question defines wake categories, making it the best answer. The other options mix in concepts from instrument approach classifications (CAT I–III), operator or mission types (general aviation, military, air taxi, air carrier), or a four-size scheme (Small, Large, Heavy and Super) that doesn’t align with the wake-category labeling used here.
