What is the minimum separation required for Wake Turbulence Intersection for a Category I aircraft behind Category E?

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

Answer: (B)

The minimum separation of 2 minutes for wake turbulence at an intersection when a Category I aircraft is following a Category E aircraft is based on established guidelines for maintaining safe operations in air traffic control. Category I aircraft, which typically includes smaller jets and general aviation aircraft, are more susceptible to the effects of wake turbulence generated by larger Category E aircraft, such as heavy jets and large transport planes.

The 2-minute separation allows enough time for the wake turbulence created by the Category E aircraft to dissipate to a safer level before the Category I aircraft begins its takeoff or landing. This guideline is critical for ensuring that the following aircraft can safely navigate through the wake turbulence without experiencing undue disturbance that could lead to loss of control or difficulty in maintaining a stable flight path.

In this scenario, the other options do not reflect the standard practice, which has been developed through extensive safety research and historical data on incidents involving wake turbulence. Therefore, 2 minutes is the correct and recommended minimum separation time for this situation.
