To obtain the aircraft ground speed during Instrument Landing System approaches an algorithm is developed which utilizes the glide slope deviation signal and the rate of descent as determined from the radar or barometric altimeter. The accuracy of these inputs is determined from a study of all appropriate Federal Aviation Administration Flight Inspection Records and from examination of topographic maps of the areas beneath the flights for which records were available. It was found that irregularities in the glide slope, variations in the slope of the terrain, and rapid fluctuations in the barometric pressure associated with wind shear will all induce excessive errors in the value obtained for the ground speed.
