Changes In How Aircraft Evacuations Are Evaluated.

Sat Sep 18, 1999 12:54 pm

I got this from, this revelation has surprised me considering in the past there has been so much empathsis placed on aircraft safety and evacuations. How much more effort would it take for aircraft manufacturers to do the full scale tests with "real" people.

The FAA's long-standing policy to require full-scale emergency evacuation testing of new airliner designs is changing. Now, aircraft manufacturers can show "analysis" instead to prove that all occupants of the plane can be safely evacuated. The NTSB opposes the decision, saying analysis of the type the FAA is talking about is unreliable and unsafe.

How does everyone else feel about this new policy? Even with all the computer technology it still just is not the same.

As a flight attendant I would like to think that real situations involving peolpe are utilised when trialing evacuation times and procedures for new aircraft and also when cabins are reconfigured. Some aircraft simply by virtue of the internal layout are more difficult to exit than others of the same type but with different configurations of seating and galley areas. It is one thing to use theoretical figures. When real people are involved the human factor comes into play and I believe the situations could be very different, particularly with regards to the composition of the "pax" group. One must also bear in mind the test scenarios are quite unlike the real situation where the people being evacuated following an actual incident will be traumatised and /or in shock when the evacuation takes place. Probably the reality of the changing test methods is simply to avoid the inevitable injuries to the volunteers that do occur whenever mock evacuations are trialed. Our training department for example no longer requires flight attendants to slide from the B747 upper deck slides as too many back and limb injuries have occurred over the years. It is a catch 22 situation I'm afraid. My thoughts only,
