The input data on which these NEF contours are based have been provided from several sources as follows: Airport operations data were supplied by the FAA; (Number of operations, type of aircraft, flight path, time of day, runway utilization). Aircraft performance data were supplied by the aircraft manufacturers. Aircraft gross weight distribution by aircraft type for operations from O'Hare were supplied by the airlines. The procedure for computing NEF contours was developed and approved by SAE Committee R2.5. The computing and plotting work was accomplished by the aircraft manufacturers. (Author)
