Abstract : Data were recorded from 658 aircraft in the enroute IFR environment. Aircraft samples included Air Carrier, Military, and General Aviation operations. Altitudes of aircraft sampled ranged from the Minimum Enroute Altitude (MEA) through Flight Level (FL) 450. Electronic radials were checked before, during, and after data acquisition periods. Deviations from airway/route radials were analyzed statistically to determine mean and standard deviation. Data were found to be normally distributed. Deviation from centerline was not affected by aircraft category (air carrier, military, or general aviation). Deviations increased as distance from the navigation facility increased. Deviations were affected by altitude groupings (above or below FL-180). Flight Technical Error (pilotage factor) was found to be linear rather than angular. It was determined that present airspace structure for enroute airways/routes could be modified with substantial savings in airspace. (Author)
