For Wake Turbulence Intersection separation, when a Category I aircraft is following a Category F, G, or H aircraft, a separation of 3 minutes is required. This guideline is established to ensure safety and minimize the risk of wake turbulence, which can be particularly hazardous for smaller or lighter aircraft that may be more affected by the vortices generated by heavier aircraft.

The 3-minute separation allows adequate time for the wake turbulence to dissipate, thus providing a safer environment for the following aircraft to take off or land. This time frame is based on operational data and research that indicates the behavior of wake turbulence as it relates to different categories of aircraft. The regulatory frameworks govern these requirements to ensure all flight operations maintain high safety standards while minimizing turbulence-related incidents.

Therefore, recognizing the proper interval is crucial for air traffic controllers to manage aircraft safely during takeoff and landing phases, especially at busy airports where different categories of aircraft may be operating in close proximity.
