Which hard button on the far turns on the Emergency Signaling System?

• A. CMD
• B. EVAC CMD
• C. EMER CMD
• D. SOS

Answer: (B)

Activating the Emergency Signaling System is done with the dedicated Evacuation Command button. This button is specifically labeled for evacuations and, when pressed, triggers the full evacuation signaling for the cabin and flight deck—an alarm, alerts to crew, and the coordinated evacuation flow. Other buttons serve different purposes: a general emergency command doesn’t initiate the full evacuation signaling, and an SOS/ distress button is for separate distress signaling rather than the ESS evacuation sequence. So Evac CMD is the correct control to turn on the Emergency Signaling System.
