Noise measurements were performed on five VFR Military Training Routes. The objective was to determine the lateral distribution of operations across these routes, in order to validate or update the structure of the ROUTEMAP noise prediction model. It was found that distribution of operations about the centerline is Gaussian, as embodied in the current version of ROUTEMAP. It has been established from the current measurements that the standard deviation of flight tracks is generally 0.17 times the route width. This dispersion is due to a combination of a missions using a variety of nominal tracks and b the variation inherent in visual navigation. In situations where there is only one nominal track route width less than 6 nautical miles, choke points, or specific local conditions, the standard deviation is one nautical mile. Recommendations are made for revisions to ROUTEMAP to incorporate these new results. Aircraft noise, Military aircraft operations, Community noise exposure.
