Patent ID: 7844622

Claim:
A method of computer generating a product specification for a passenger vehicle product for a user, said method comprising: presenting a plurality of locations; receiving a selection of a location from said plurality in which said passenger vehicle product will be operated; providing an initial product specification of said passenger vehicle product while automatically including any features in said initial product specification if the features are required in the location; displaying a depiction of the initial product specification; determining whether an added option regarding a physical feature of the passenger vehicle product would result in an altered product specification which is in compliance in said location by referencing a data file, said data file including information regarding at least one regionally-specific requirement in said location; displaying a depiction of the altered product specification which includes the added option; automatically informing said user of whether said added option causes said altered product specification to be in compliance enabling the user to eliminate a formerly-existing physical feature in said specification to result in a remaining specification; reflecting the removal of the formerly-existing physical feature in a stripped three-dimensional representation of said remaining specification upon the user's elimination of the formerly-existing physical feature; determining whether the remaining specification is in compliance in said plurality of places the aircraft is intended to be operated; executing said determining step by referencing the at least one data file or another data file which includes regionally-specific requirements in the plurality of places in which the aircraft is intended to be operated; automatically displaying an indication of whether the remaining specification is still in compliance; and continually displaying a total weight for the aircraft product.
