The Federal Aviation Administrations Integrated Noise Model INM is a series of computer programs designed to estimate environmental noise levels in the vicinity of an airport. As part of MITREs efforts to validate INM computations for the FAA, a comparison was made between arrival and departure profiles contained in the INM data base and those observed in actual operations at the Seattle-Tacoma International Airport. ARTS-III radar data were used to determine actual altitude and velocities of aircraft at various distances from the runway during arrival and departure operations. This report presents the results of the comparison.
