In an inflight emergency, which entity should flight crew inform about all dangerous goods being carried?

• A. Captain
• B. IOC
• C. ATC
• D. Med Link

Answer: (C)

The main idea here is coordinating with the external authorities who manage safety in the airspace and on the ground. When dangerous goods are on board, it’s crucial that the flight crew inform the right external agency so that precautions can be taken and emergency responders can be prepared if needed. Air Traffic Control is the appropriate channel because they connect the airplane with airport emergency services, ground crews, and other authorities, and they can adjust routing, spacing, and response plans based on the hazard. They need to know what dangerous goods are on board, where they are located, and the potential risks, so they can relay accurate information to responders and coordinate a safe outcome. The other entities handle different functions—onboard command, internal airline operations, or medical emergencies—but informing ATC directly ensures external safety and effective coordination during an inflight emergency.
