I have a few question on emergency exits for airplanes : Is the "must be able to empty plane in 90 seconds" a real requirement or just urban legend ? Are there specific and widely accepted ways to measure each exit's capacity in an emergency ? If so, what are the criteria used ? (door size, chute length, cabin/aisle design ?) Or do aircraft manufacturers actually load up a plane with people and make the test ? Does anyone have specific numbers on how many passengers a full fledged door (with chute) can process (per minute ?) and how over-wing exits fair in that regard ? If the "90 seconds" requirement is true, does it apply to a plane with all of its doors usable, or does it assume that a certain percentage of its doors will be unusable ?
