The study was designed to develop and analyze an aircraft takeoff noise data base consisting of areas and populations, computed as a function of noise level, aircraft type, weight and takeoff flight procedure. Six aircraft, each at typical and maximum weight, were chosen to represent the range of civil transport aircraft and engine types. Six types of takeoff flight procedures were selected, three involving cleanup of flaps and leading edge devices before thrust cutback, and three involving thrust cutback before or during cleanup. Each of these procedures was initiated at 3 altitudes: 122, 305, and 610 meters, so that for each combination of aircraft and weight a total of 18 takeoff procedures were considered, for a total of 216 cases.
