An emergency call from the flight deck is indicated by which combination?

• 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

Answer: (A)

An emergency call from the flight deck is shown by both a visual and an audible cue, so the crew knows it’s urgent and must respond immediately. Specifically, you’ll see a flashing light at the call indicator and hear a three-tone HI/LO sequence. The flashing light catches attention in a noisy cabin, while the distinct three alternating tones signal the elevated urgency of an emergency from the flight deck. If you only had one cue, it could be a less urgent call or a normal alert, but the combination of both a flashing light and the three HI/LO tones confirms an emergency call.
