re Evacuation time FAR 25.803 Emergancy Evacuation (c) For ailplanes having a seating capacity of more than 44 passengers, it must be shown that the maximum seating capacity, including the number of crewmembers required by the operating rules for which certification is requested, can be evacuated from the airplane to the ground under simulated emergancy conditions within 90 seconds. Compliance with thie requirement must be shown by actual demonstration using the test criteria outlined in Appendix J... Appendix J (a) The emergancy evacuation must be conducted either during the dark of the night or during daylight with the dark of night simulated. (f) Each external door and exit, and internal door or curtain, must be in the takeoff configuration. (h)(1) At least 40% must be female (h)(2) At least 35% must be over 50 (h)(3) At least 15% must be female over 50 (h)(4) Three life-size dolls, must be carried to simulate live infants 2 years or younger (k) Before the start of the demonstration, approximately one-hald of the total average amount of carry-on baggage, blankets, pillows, and other simular articles must be distributed at several locations in aisles and emergancy exit access ways to create minor obstructions. (p) Not more than 50 percent ofthe embergancy exits in the sides of the fuselage of an airplane that meets all of the requirements applicable to required emergancy exits for that airplane may be used for the demonstration. Exits that are not to be used in the demonstration must have the exit handle deactivated or must be indicated by red lights, red tape, or other acceptable means placed outside the exit to indicate fire or other reason why they are unusable. The exits to be used must be representative of all of the emergancy exits on the airplane. (s) The evacuation time period is completed when the last occupant has evacuated the airplane and is on the ground. This is typically a demonstration which results in injuries. During the MD-11 program, on of the (h)(3) classification dove out the door, overshot the ramp and broke her neck. Friction burns and broken arms are also typical injuries (as they are during actual emergancy conditions). In the UK a test was done where the passengers were paid for each item of carry on they managed to take out with them. The demonstration was VERY realistic in that it turned violent as passengers fought to get out with their 'stuff.' Hope this answeres your questions.
