In high-traffic ground conditions, what practice helps reduce taxiway congestion?

• A. Allow arbitrary taxi routes to save time.
• B. Pre-briefed, clear taxi routes and proactive sequencing with ground control.
• C. Coordinate with Approach Control to speed up departures.
• D. Let pilots navigate on their own.

Answer: (B)

In high-traffic ground conditions, organizing taxi operations with pre-briefed routes and proactive sequencing is essential to keep the movement on the ground smooth and predictable. When routes are clearly pre-briefed, pilots know exactly which path to follow, where to expect intersections, and where holds may occur, which reduces last-minute changes, wrong turns, and backtracking that cause bottlenecks on taxiways. Proactive sequencing with ground control further helps by assigning a sensible order and timing for taxiing, allowing controllers to stage departures and arrivals so aircraft move in a steady flow rather than bunching up at intersections or the runway. Together, these practices lower taxi time, reduce conflicts, and improve overall ground throughput. Relying on arbitrary routes, coordinating with Approach Control to speed up departures, or letting pilots navigate on their own all tend to increase confusion, inefficiency, and congestion on the ground.
