AbstractThis is the first of three reports containing the results of an NEF validation study for Transport Canada. Summaries of the other two reports are included in Appendix 2 of this report. The NEF_1.7 program is a critical part of the management of airport noise in Canada, and it is extremely important that its validityand accuracy be as good as is reasonably possible. The use of millions of dollars worth of land near airports is determined by the noise level contours from this program. Similarly, the acceptability of land nearairports for residential use is determined from the calculated noise contours produced by the NEF_1.7 program. The analyses of this report suggest that improving the detail of the flight path description anddeveloping a more correct excess ground attenuation calculation procedure would considerably improve the NEF_1.7 program. It is therefore essential that the required continuing development of the NEF_1.7 program receive the necessary financial and technical support. The analyses of this report were focused on the errors associated with predicting noise levels around airports. The related problems of determining acceptable noise level limits and the practical application of these limits will be considered in a second report. These two reports will form the technical background for a final report evaluating the use of theNEF measure to quantify airport noise levels near Canadian airports.
