How should you signal the pilot in an emergency?

• A. Radio call only
• B. 4 high low chimes
• C. Flashing cabin lights
• D. Shout 'Panic!'

Answer: (B)

In an aircraft, emergencies are signaled to the flight deck with a standardized audible alert that is built into the cabin crew signaling system. The four-chime pattern, often implemented as a sequence of high and low notes, is designed to cut through normal cockpit noise and grab the pilots’ immediate attention. This signal is recognized across crews as an urgent call and prompts a quick, prioritized response. Relying on a radio call alone may not convey the urgency as reliably, and shouting or flashing cabin lights can create confusion or panic rather than a clear, professional cue. The four-chime alert provides a clear, standardized method that communicates “emergency—immediate attention” to the pilots.
