For flight conditions, data are presented in terms of various acoustic measures over the range 200-25,000 feet minimum slant distance to the aircraft. For ground runups, data are presented as a function of angle and distance to the aircraft. All of the data are normalized to standard acoustic reference conditions of 59 deg. F temperature and 70% relative humidity. Noise data are presented in this Volume 4 for the following aircraft: F-100C, D, F; F-101B, C, F; F-102A; F-105B, D, F, G; F-106A, B; T-33A; T-37B; T-38A; T-39A, B, F; T-43A; and U-2. 收起
