description Automated systems and methods that utilize high-accuracy landing system data to correct the position of a synthetic runway presentation on a pilot display. This is achieved by first computing the "synthetic" lateral and vertical rectilinear deviations of the airplane from an ideal beam using the airplane's GPS position and barometric altitude, the runway location and orientation contained in an airborne database, and approach angle information. This synthetic deviation data is then compared to rectilinear deviation data computed by the computer system as received from a ground installation. The computer system is programmed to determine the differences between the ground-based and GPS-based rectilinear deviation data and then compute a corrected position vector using those differences. The position of the synthetic runway symbology on the pilot display is adjusted as a function of the corrected position vector.
