Situations presenting an immediate hazard concerning safety of flight must be reported to the ___________.

• A. ATC facility most concerned
• B. Flight service
• C. Airport operations
• D. Local control tower

Answer: (A)

When something presents an immediate hazard to safety of flight, report it to the ATC facility with jurisdiction—the one most concerned. ATC has the authority and capability to rapidly disseminate the hazard, issue priorities, and coordinate with other flights to maintain safe separation. Which facility that is depends on where you are: the local control tower if you’re in the terminal area around a specific airport, or the appropriate air route traffic control center if you’re en route. Flight Service handles weather and planning information, not real-time hazard coordination, and airport operations or a local tower don’t cover the full scope of immediate in-flight safety communication across airspace.
