Abstract: There is provided a method and apparatus for simulating a flight scenario during a live flight of an aircraft. The method comprises: (i) generating (60) images comprising scenes relevant to the simulated flight scenario at a simulated altitude; (ii) calculating, using live flight data received for the aircraft and with reference to a predetermined flight model (65), simulated flight data for the simulated flight scenario at the simulated altitude; and (iii) displaying, on a display system (35) of the aircraft, the calculated simulated flight data while controlling the display of said generated scene images to simulate movement of the aircraft through the displayed scene at a rate and in a direction corresponding to the displayed simulated flight data. The method and apparatus may optionally alter the response of the aircraft to control actions (70) by a pilot to simulate the response expected of the aircraft having the simulated flight characteristics.

Abstract: A map display device stores a map image dataset with image pixels including a plurality of static-type pixels each having only one color value, and a plurality of dynamic-type pixels each having a predefined set of color values, and a function definition field which defines a function to select between said color values. A graphics processor processes one tile of map image data by, for each of the dynamic type pixels, retrieving the function identified by the function definition field, applying a current time value to the function, and selecting one of the predefined set of color values according to a result of the function. An output unit outputs the map image frame as a raster image containing one pixel color value at each of the pixels for display on a display screen.

Abstract: A map display device 200 stores a map image dataset 211 with image pixels including a plurality of static-type pixels 410 each having only one color value 412, and a plurality of dynamic-type pixels 420 each having a predefined set of color values 422-426, and a function definition field 428 which defines a function to select between said color values 422-426. A graphics processor 220 processes one tile 401 of map image data by, for each of the dynamic type pixels 420, retrieving the function identified by the function definition field 428, applying a current time value to the function, and selecting one of the predefined set of color values 422-426 according to a result of the function. An output unit 230 outputs the map image frame as a raster image containing one pixel color value at each of the pixels for display on a display screen 240.

Abstract: A method of producing male or female sterile plants comprising the steps of transforming plant material with a polynucleotide which encodes at least one enzyme which reacts with a non-phytotoxic substance to produce a phytotoxic one, and regenerating the thus transformed material into a plant, wherein the said non-phytotoxic substance is applied to the plant up to the time of male or female gamete formation and/or maturation, so that the non-phytotoxic substance provides for the production of a phytotoxic one which selectively prevents the formation of or otherwise renders the said gametes non-functional, wherein the enzyme is expressed preferentially in either male or female reproductive structures, characterised in that (i) the non-phytotoxic substance is selected from the group consisting of ester derivatives of non-phosphonate herbicides which herbicides are directly phytotoxic to non-green tissue, D-alpha amino acids, peptide derivatives of non-protein D-alpha amino acids, S-enantiomers of aryloxyphenoxy
