What should ground control provide to pilots to minimize taxiway congestion?

• A. Pre-briefed, clear taxi routes and proactive sequencing.
• B. Ad hoc directions on demand.
• C. Only a single fixed route regardless.
• D. No taxi instructions.

Answer: (A)

Providing pre-briefed, clear taxi routes and proactive sequencing helps create a predictable, orderly flow of aircraft on the ground. When pilots know the exact routes they should follow and the planned sequence for taxiing, they can move efficiently without unnecessary backtracking or last-minute coordination at intersections. This reduces conflicts between aircraft, minimizes delays from holds, and lowers overall taxi times, which in turn decreases taxiway congestion. Ad hoc directions on demand introduce uncertainty and variable routing that can lead to bottlenecks and more radio traffic. Limiting everyone to a single fixed route ignores real-time conditions and gate positions, creating rigid bottlenecks. Without any taxi instructions, pilots would be left guessing, increasing confusion and the potential for congestion.
