What is the wake turbulence separation time for an aircraft behind a Category B or C?

• A. 1 minute
• B. 2 minutes
• C. 3 minutes
• D. 4 minutes

Answer: (B)

The appropriate wake turbulence separation time for an aircraft following a Category B (small aircraft) or C (medium aircraft) is indeed 2 minutes. This separation time is established to ensure safety, as wake turbulence can be particularly hazardous to smaller and lighter aircraft.

The International Civil Aviation Organization (ICAO) and various air traffic control authorities have implemented these time intervals based on an understanding of how long wake turbulence can remain a hazard after an aircraft has passed. Category B represents small jet aircraft, while Category C encompasses larger jets. The 2-minute interval allows sufficient time for the wake to dissipate, thereby reducing the risk of encountering turbulence and maintaining safe operational conditions.

Recognizing the need for effective management of wake turbulence is vital in maintaining safety in controlled airspace, especially in busy terminal environments where category B and C aircraft often operate.
