ABSTRACT:
A plan position indicator display is converted to a correctly scaled perspective display based on aircraft altitude and display parameters. Two cartesian based display memories are involved. One memory stores the plan position indicator image to be converted and the other memory stores the converted image ready for direct display on a bit-mapped display device. The arrangement is such that a plan position indicator display pixel address is provided for each pixel in the memory which stores the converted image for permitting said latter memory to be completely filled with the most appropriate pixel values at the frame rate without the need for further pixel filling or erasing.
