How is a Category E aircraft separated from a Category B arrival if they are on intersecting paths?

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

Answer: (B)

The correct approach to separate a Category E aircraft from a Category B arrival on intersecting paths is by utilizing a 2-minute separation standard. This 2-minute interval is established based on the capabilities and performance of both categories under typical operational conditions.

Category E aircraft, which generally refers to large turbojet aircraft, require more distance due to their speed and wingspan, while Category B includes smaller turbojet aircraft that may not require as much spacing. By employing a 2-minute separation, air traffic controllers manage the potential wake turbulence and ensure safe distances between the aircraft, thus minimizing risk during critical phases of flight such as approach and landing.

This standard is particularly important in busy air traffic environments, where intersections of flight paths are common. The established separation helps to maintain safe operational flow without imposing excessive delays on incoming flights. Understanding these separation standards is crucial for maintaining safety in terminal airspace and ensuring efficient air traffic management.
