During evacuation initiation, what action do flight crew perform?

• A. They shout evacuation commands
• B. They announce BRACE FOR IMPACT
• C. They prompt passengers to prepare
• D. They announce "EVACUATE" on the PA and press the Evac CMD to sound the evacuation horn

Answer: (D)

During evacuation initiation, the essential step is to deliver a clear, standardized instruction and activate the safety alerts. The flight crew announces EVACUATE over the public address system and press the Evac CMD to sound the evacuation horn. This combination ensures every passenger hears an unambiguous command to leave the aircraft and triggers the alarm and door/slide systems, so the evacuation can proceed in a coordinated, timely manner. Shouting commands, or actions like BRACE FOR IMPACT, are not the initiating procedure for an evacuation, and simply prompting passengers to prepare does not activate the necessary alarms or guide immediate action.
