Evacuation slide
inflatable slide for evacuating the occupants of a vehicle, aircraft, ship or an elevated location in an emergency
An evacuation slide is an inflatable slide used to evacuate an aircraft quickly. An escape slide is required on all passenger-carrying aircraft if the door is too high for passengers to step down from the aircraft uninjured. Federal Aviation Administration requires slides on doors where the floor is 6 feet (1.8 m) or more above the ground.
Some slides are designed to act also as life rafts if the plane lands in the water.
