In a previous study, a method was developed for obtaining navigational data from operational missions by means of postflight reports by the pilot. In this study, a series of flight tests were conducted to determine the validity of navigational data obtained by that method. Two fixed-wing squadrons and two rotary-wing squadrons flew a total of 39 low-altitude sorties, and an objective record of the track of each sortie was obtained. During fixed-wing sorties, the objective track was determined by chase pilots during rotary-wing sorties it was determined by Decca Flight Logs. After each sortie, the pilot marked on his aeronautical chart the track he recalled having flown. Measurements of navigational errors were made from the objective tracks and compared with those made from the recalled tracks. Author
