  1. Aircraft Emergency Evacuation Study with Injured Passengers Hae Chang Gea Department of Mechanical and Aerospace Engineering Rutgers University, New Jersey, USA Program Manager: Dr. Mac McLean, FAA, CAMI

  2. Aircraft Emergency Evacuation • Grouped Passenger Behaviors During Emergency Evacuation (Cabin Safety I: 10:30-11:00AM) • Aircraft Emergency Evacuation Study with Injured Passengers (Cabin Safety II: 2:30-3:00PM) • Computer Simulations on Interior Access Vehicles for Emergency Evacuation (Cabin Safety II: 4:30-5:00PM) A full scale test is… • risky, costly, time consuming and inconsistent. Simulations can… • study what-if scenarios and hazardous conditions; • better understanding of the entire evacuation process.

  3. Injured Passengers Injured Passengers • We are referring to all passengers who move in slower speed than regular passengers. • Examples: injured passengers, disabled passengers, and passengers need special assistant.

  4. Outline Injured Passengers with Random Seating • Single Aisle Vehicle • Double Aisle Vehicle Injured Passenger with Assigned Seating • Single Aisle Vehicle • Double Aisle Vehicle Accidental Injury during Emergency Evacuation • Single Aisle Vehicle • Double Aisle Vehicle Conclusions

  5. Randomly Seated Injured Passengers on Single Aisle Vehicle
