An improved inflatable over-the-wing evacuation slide. The slide is provided with an inflatable wing ramp section projecting from the foot of the wing exit door to a point on the aircraft wing remote from the door. The wing ramp section also includes a generally flat upper or walkway surface and a lower face surface projecting in a tapered contact with the sloping aircraft wing. It also includes a pair of inflatable guard rails attached to the side margins of the inflatable wing ramp. The wing ramp then includes a right angle turn remote from the exit door and continues to terminate in an extended section proceeding from the wing to the ground. A unique support system is provided on the underside of the central portion of the extended ramp consisting of inflatable portions shaped to provide support to the slide regardless of the position of the trailing edges of the wing flaps. A continuous inflated floor configuration is thus provided which presents a smooth uninterrupting walking surface to the steeper slide section of the unit. The walking surface eliminates the joint between the two distinct inflatables sections, on the wing and beyond, which can, at times, present a tripping point for the people evacuating the aircraft when using the inflatable device.
