Accidents Are SurvivableAccident ComparisonCabin Crew and Emergency ExitsDifferent Types of ExitsSlide Or Jump?Passenger BehaviourSmoke and DarknessOther FactorsDecision to EvacuateEvacuation TestsAccording to the European Transport Safety Council (ETSC), 90% of commercial transport aeroplane accidents can be categorised as survivable or technically survivable. Even in catastrophic circumstances, such as fire or fuselage disruption, a high level of occupant survivability can be achieved. Effective crew procedures and associated training can increase the probability of a successful evacuation and the more rapidly an evacuation is started and efficiently conducted, the more likely the number of injuries and fatalities to occupants will be reduced. There have been a number of studies published on emergency evacuation by aviation authorities. In June 2000 the US National Transportation Safety Board (NTSB) issued Safety Study: Emergency Evacuation of Commercial Airplanes, which included 20 safety recommendations.
