In addition to ATC, which office may authorize taxi movements on the airfield?

• A. Base Security Office
• B. Maintenance Control
• C. Airfield Operations Controller
• D. Public Affairs Office

Answer: (C)

Coordinating safe movement on the airfield surface is handled by the Airfield Operations Controller, who has authority to authorize taxi movements in addition to ATC. This office oversees all ground surface operations—defining taxi routes, confirming vehicle and aircraft sequencing, and ensuring there are no conflicts with active aircraft or other traffic on runways and taxiways. While ATC handles airspace clearance, the Airfield Operations Controller ensures the taxiing process itself can proceed safely and smoothly.

Base Security Office focuses on perimeter security and access control, not the day-to-day authorization of taxiing. Maintenance Control tracks aircraft status and maintenance needs, not movement approvals. Public Affairs handles external communications and information, not airfield movement authority.
