A structural system for capturing, supporting, and releasably securing a tail ramp toe of an aircraft, while the aircraft is either on the ground or in flight. The preferred embodiment of the ramp toe stowage system is adapted for use with a cargo aircraft having: a downwardly and outwardly opening tail ramp, with at least one ramp toe removably attached to it; and, an upwardly and inwardly opening tail door that is complementary to, and aft of, the tail ramp, with the tail door having an internal surface. The stowage system is located over, and is attached to, the internal surface of the tail door, and includes two horizontally positioned tracks that accept complementary guide rollers which are on the side edges of the ramp toe, near the known center of gravity of the toe. Unlike the prior art, the system requires only one man to stow the ramp toe, or to release it from stowage, even while the aircraft is in flight.

A ramp toe storage system, adapted for use with a cargo aircraft having a tail, a downwardly and outwardly opening tail ramp having at least one ramp toe removably attached to said tail ramp, and an upwardly and inwardly opening tail door complementary to and aft of said tail ramp and having an internal surface, wherein said tail ramp and said tail door can be opened and closed while said aircraft is airborne and also when said aircraft is on the ground, and wherein said ramp toe has a first side edge, a second side edge, a first end edge, a second end edge, and a known center of gravity, comprising: a. means for capturing and supporting said ramp toe, with said capturing and supporting means located over, and attached to, said internal surface of said internal surface of said tail door wherein said ramp toe capturing and supporting means includes: (1) first track member and a second track member in parallel and equal spaced-apart relationship to each other, with each said track member in a horizontal position and having a groove therein, and with said track members disposed such that said groove in said first track member and said groove in said second track member are mutually opposed, and wherein each track member has a first end, a second end, and inner surface and an outer surface, and wherein each groove has an upper surface with a recess therein at said first end of its respective track member, with each said recess in communication with its respective groove; (2) means for holding said track members over, and for connector said track members to, said internal surface of said tail door; (3) a first biased latching means connected to said first end of said first track member; (4) and, a second biased latching means connected to said first end of said second track member; b. means for slidably engaging said ramp toe with and to said capturing and supporting means, with said engaging means operatively associated with said capturing and supporting means; c. and, means for releasably securing said ramp toe to said capturing and supporting means in a, and at a, preselected position, with said securing means in operative association with said capturing and supporting means and with said ramp toe.
