Which of the following is a traffic management initiative used by the FAA to manage capacity and delay?

• A. Mile-in-trail
• B. Traffic reroutes
• C. Ground delay
• D. Metering

Answer: (B)

When capacity or weather constraints impact the system, adjusting how flights move through airspace can keep the overall flow balanced. Directing aircraft along alternative routes to avoid congested or affected airspace is a traffic management initiative used by the FAA to manage capacity and delay. This rerouting distributes demand across available routes, helps prevent bottlenecks, and can reduce the need for holds or widespread ground delays by keeping airplanes moving along less constrained paths. Other methods like spacing (mile-in-trail), delaying departures on the ground, or sequencing arrivals through metering are also used in flow management, but rerouting specifically targets capacity by changing the flight paths themselves to smooth overall delays.
