Claim 15:
16. The apparatus according to claim 1 and further comprising:
a ramp hinge, wherein the ramp is rotatably movably mounted in operative connection with the emergency exit door through the ramp hinge,
wherein in the open position of the emergency exit door the ramp is enabled to rotate in operatively engaged relation with the emergency exit door between the extended position and a retracted position about a ramp hinge axis,

at least one ramp spring, wherein the at least one ramp spring is in operative connection with the ramp,
wherein in the open position of the emergency exit door the at least one ramp spring is operative to automatically cause the ramp to rotatably move about the ramp hinge axis in a first rotational direction from a retracted position to the extended position,
wherein in the extended position the ramp is extendable between the emergency exit door and ground,
and further including at least one leg, wherein the at least one leg is movably mounted in operative connection with the ramp, wherein the at least one leg is rotationally movable relative to the ramp about a leg axis,
wherein in the extended position of the ramp the at least one leg is rotatable in the first rotational direction about the leg axis to a leg deployed position in which the at least one leg operatively extends between the ramp and ground.
