Which duty is part of AMOS/AMSL responsibilities?

• A. Situational awareness of airfield activities
• B. Develops a monthly duty schedule
• C. Maintains a locally developed airfield lighting outage chart
• D. Functions as AFM during absence

Answer: (A)

The key idea is that AMOS and AMSL responsibilities center on keeping a clear, real-time picture of what’s happening on the airfield so operations stay safe and coordinated. Having situational awareness means continuously monitoring airfield activities—aircraft movements, active and closed runways, taxi routes, lighting status, construction or maintenance impacts, and any incidents. With that up-to-date view, AMOS/AMSL can communicate effectively with air traffic control, maintenance crews, security, and weather personnel, adjust ground operations as needed, and ensure the field operates smoothly and safely.

Administrative tasks like popping in a monthly duty schedule are more about staffing and shift assignments than day-to-day airfield management. Maintaining a locally developed airfield lighting outage chart is important and related to AMSL duties, but it’s a specific documentation task rather than the ongoing situational awareness that underpins all AMOS/AMSL activities. Functioning as the Airfield Manager during absence is a temporary acting role, not a standard ongoing duty of AMOS/AMSL.
