ABSTRACT:
A ramp toe system for use with a ramp of an aircraft, the ramp having internal and external surfaces and being pivotally attached at one end of the aircraft. A ramp extension having a proximal end fixed to the other end of the ramp and extending therefrom to a distal end, has an inside surface generally co-planar with the internal surface of the ramp, and an outside surface convergingly extending from the proximal end to the distal end. A ramp toe having first and second opposed ends and first and second opposed surfaces, the first surface convergingly extending from the first end to the second end, is pivotally attached to the distal end of the ramp extension at the first end, for selective movement between a stored position wherein the first surface is generally contiguous with the outside surface of the ramp extension, and an extended position wherein the first surface is disposed to be generally contiguous with the aircraft support surface and the second surface is generally co-planar with the inside surface of the ramp extension.
