A Study on the Airline Cabin Crew Member’s Passenger Evacuation Commands Focusing on the Brace Position and Carry-on Baggage

In the aircraft accident, the passenger survivability reaches up to 87%, if they are prepared for the aircraft crash. Most of the aircraft accident casualties take place during the crash impact and the subsequent evacuation process. The survivability depends on the brace position to be protected from the head and leg injury and the effectiveness of the egress times that are directly linked with cabin crew members' clear and assertive brace and evacuation commands. Lately airlines have introduced the passenger seat with the shoulder harness in the first and business class whereas the cabin crew member's commands for the passenger to adapt the brace position do not include this new change, leaving passengers unaware of the proper brace position. Also in most evacuations, passengers tend to slide down with their carry-on baggage, threatening to delay the evacuation. The ICAO (International Civil Aviation Organization) suggests that air carriers should establish the cabin crew training procedure to prevent passengers from sliding down with baggage. As for Korean flag carriers, the cabin crew evacuation commands either do not include the baggage related words or inappropriately sequenced, that appears to be hazards to passenger survivability in the aircraft accident. In this paper, through the comparative analysis on air carriers' cabin crew member's brace and evacuation commands, improvement methods are suggested to include the brace position with the shoulder harness in the brace commands, and the carry-on baggage related evacuation commands in the air carrier's cabin crew evacuation system in an appropriate sequence.
