A method and apparatus for analyzing passenger flow. A three-dimensional model of a passenger cabin is received. Features in the three-dimensional model of the passenger cabin are identified in response to receiving the three-dimensional model. A first plurality of objects is generated for the features in the passenger cabin. User input identifying a number of characteristics for passengers is received. A second plurality of objects for the passengers is generated using the number of characteristics. The second plurality of objects is assigned to seats within the passenger cabin. Each of the second plurality of objects is assigned a destination location and has a behavior when encountering an obstacle while moving from a current location to the destination location. A movement of the passengers to a number of locations relative to the seats assigned to the passengers is simulated using the second plurality of objects.

Aircraft passenger flow system

A vehicle () including a control system () is used for controlling vehicle attitude or angular velocity (). The processor () is coupled to a star sensor or tracker () and a memory () that may include a star catalog (), and an exclusion list (). The exclusion list (), a list of stars to be temporarily excluded from consideration when determining attitude or angular velocity or relative alignment of star sensors or trackers, is calculated on-board. Such a calculation prevents the necessity for a costly, periodic, ground calculation and upload of such data. By manipulating the star catalog, or sub-catalogs derived from said catalog, based upon the exclusion list (), measurements of such excluded stars are prevented from corrupting the attitude or angular velocity or alignment estimates formulated on board.
