 In an 14 April 2015 hearing of the DOT's Advisory Committee for Aviation Consumer Protection, Cynthia Corbett, an investigator for the Federal Aviation Administration (FAA) Civil Aerospace Medical Institute, discussed concerns regarding the emergency evacuation of higher capacity aircraft.The citizens' group "Flyers Rights" brought a case against the FAA in 2017, arguing that the agency had a responsibility to prevent seats from becoming so cramped as to become a safety issue in an emergency.This type of seat was pioneered by Recaro, but several other manufacturers (such as Weber Aircraft LLC and B/E Aerospace) have introduced their own slimline seats as well.
