An experimental trail cone stabilized static source system was fabricated and tested using various towing aircraft at speeds up to 1.12 Mach Number to determine its suitability as a standard method for determining altimeter static pressure error. Flight tests were conducted at sea level, 5, 000, 10,000, 15,000, 25,000, 30,000 and 40,000 feet, to determine the static pressure defect of the trailing cone system. Test results indicated that the experimental system had a nominal position error equal to 12 feet at sea level and 30 feet at 30,000 feet.
