If the Pressure Indicator Light is flashing red, what should you do?

• A. Notify the CA immediately
• B. Secure the cabin
• C. Open the exit
• D. Disconnect the battery

Answer: (A)

A flashing red pressure indicator signals a cabin pressure abnormality that requires immediate action by the flight crew. The correct course is to notify the Captain immediately so the flight deck can initiate the appropriate procedures, such as securing the aircraft’s pressurization plan and, if needed, initiating a controlled descent. This is a time-critical situation where the Captain is responsible for deciding the next steps and coordinating with the cabin crew. Opening an exit while the cabin is pressurized is unsafe, and simply securing the cabin or disconnecting the battery doesn’t address the immediate safety imperative of a pressure abnormality.
