What is true about the chime during cabin pressure loss?

• A. Chime will sound (if applicable)
• B. Chime will not sound
• C. Chime will repeat every 30 seconds
• D. Chime replaced by another alarm

Answer: (A)

During a loss of cabin pressure, an audible alert is used to grab attention quickly. If the aircraft is equipped with a cabin chime, it will sound to warn everyone of depressurization, usually alongside the activation of the oxygen mask signs and the fasten-seat-belt sign so people respond promptly. Some configurations may not have this chime, which is why the statement includes “if applicable.” The chime isn’t meant to repeat every 30 seconds, nor is it typically replaced by another alarm—the key idea is that, when depressurization occurs on an aircraft with this feature, the chime provides an immediate audible cue.
