Abstract: A conveyance storage apparatus includes an annular turntable having an outer circumference and a central opening defining a support surface therebetween for supporting a plurality of conveyances, particularly aircraft, on parking spaces thereon. The turntable is supported on a foundation, and a rotation assembly is positioned between the turntable and the foundation for permitting rotation of the turntable on the foundation between storage and enter/exit positions. A stationary core is positioned within the central opening of the turntable and the turntable is mounted for rotation around the stationary core. The turntable can be positioned within an enclosure having an opening sized to permit only a single conveyance to enter or exit the enclosure at a time. The rotation assembly is electronically programmable to respond to a predetermined access code by moving a predetermined parking space to a conveyance entrance/exit position in relation to the enclosure opening.
