How often must aircraft and vehicle traffic be monitored on the airfield?

Answer: B — Continuously for ongoing safety

Monitoring aircraft and vehicle traffic continuously on the airfield is essential for ensuring ongoing safety. This practice allows for real-time awareness of any potential hazards, changes in conditions, or the movements of aircraft and vehicles. Continuous monitoring helps in quickly identifying and responding to emergencies, maintaining safe operational environments, and ensuring compliance with established safety regulations. While hourly checks or daily compliance measures may provide some level of oversight, they do not match the immediacy and responsiveness that continuous monitoring offers. Weekly evaluations may also miss critical incidents and hazards that could occur at any moment. Therefore, the emphasis on continuous monitoring aligns with the high stakes involved in airfield operations, where safety is paramount.
