Noise Modeling Analysis

The Federal Aviation Administration (FAA) used the Integrated Noise Model (INM), Version 6.1, to support the aircraft noise assessments for the interim conditions presented in Chapters 2 and 3 and Appendix C in the Draft Re-Evaluation. The same version of INM was also used for the analysis of the interim conditions in the EIS.

The INM is a computer program used to evaluate the noise exposure effects associated with aircraft operations in an airport environs. Based on a series of data inputs the model produces noise exposure contours which are computer generated lines connecting points of equal levels of noise resulting from aircraft operations. The primary inputs to the model include runway location and orientation, average annual day operations by aircraft type and time of day, runway use and flight paths.

The links below connect to the INM input and output file set for each respective interim condition.
