ABSTRACT:
A system and method is provided for rapidly reconfiguring a jet aircraft from a cargo or passenger configuration into a parabolic flight configuration. In the parabolic flight configuration, a zero-gravity condition is created in the aircraft cabin to simulate a weightless atmosphere which can be provided as entertainment to paying customers. Various aspects of the invention include a hydraulic system design change which prevents loss of hydraulic function during a zero-gravity condition and a strap-down accelerometer which provides a visual indication of the parabolic flight condition. Additional interior modifications include removable padding areas, a dual-purpose interior gill liner, modified oxygen systems, handrail attachment fixtures, modified emergency lighting systems, and a palletized floor assembly.
