During an emergency call from the flight deck on a CRJ 900, what indication should flight attendants observe and hear?

• A. A flashing light is observed and a three HI/LO tone is heard
• B. A flashing light is observed
• C. A three HI/LO tone is heard
• D. No indication is observed

Answer: (A)

When the flight deck places an emergency call, the cabin receives both a visual and an audible alert. A flashing light is activated to grab your attention, and simultaneously you’ll hear a sequence of three HI/LO tones. This dual cue ensures the crew notices the call quickly in any cabin situation and clearly recognizes it as an emergency.

That’s why this option is the best: it matches both the visual signal and the distinctive audible alert used for emergency calls on the CRJ 900. A flashing light or a tone alone wouldn’t reliably convey the urgency, and there would be a risk of missing the alert.
