Abstract: A method for displaying a datablock (31) on an air traffic control display system that upon each update changes a display offset angle of the datablock by a predetermined increment to either (1) rotate the offset angle toward a desired offset angle if the datablock can be displayed at the rotated offset angle without generating overlap between a padded bounding rectangle (53) of the datablock and padded bounding rectangles of any other datablocks, or (2) minimize overlap of the padded bounding rectangle of the datablock with padded bounding rectangles of other datablocks.

Abstract: A video display system that includes a video display for displaying a raster image comprised of an array of pixels arranged in rows and columns, a video memory for storing pixel raster image data for the raster image, a bit-map memory, and a processor for rendering into the bit-map memory updated pixel raster image data for a rectangular region of pixels of the raster image that is less than the entire raster image, and for copying the updated pixel raster image data to the bit-map memory at locations that store raster image data for the rectangular region of pixels.

Abstract: A method for interactively displaying flight information in an air traffic control system. Flight information lists are displayed relative to associated geographic fixes, and further flight information is displayed pursuant to user selection of an item on a flight list.
