Appendix B Data Modeled for Noise Predictions

Appendix B – Data Modeled for Noise Predictions B-1 The following appendix provides a summary of input data used to produce the modeled noise metrics presented in  Chapter 4.    HMMH has developed a preprocessor named RealContoursTM that converts radar flight tracks to Integrated Noise  Model (INM) tracks, thereby modeling each and every radar flight as an INM flight track and producing daily  contours, which are then averaged to provide annual noise metrics.  RealContoursTM uses individual flight tracks  taken directly from radar systems rather than relying on consolidated, representative flight track data.  This  provides the advantage of modeling each aircraft operation on the specific runway it actually used and at the  actual time of day of the arrival or departure.  RealContoursTM then sets up an INM study for each day using the  INM standard data.  Each day is then modeled in the INM and the results for each day combined and averaged to  get the annual DNL contours.  The RealContoursTM approach essentially eliminates the approximation associated with the use of a limited set of  prototypical modeling tracks by applying the INM’s modeling capabilities on a flight‐by‐flight basis for over 138,000  tracks. This methodology, including the use of RealContoursTM, has been used for a variety of other FAA‐funded  and reviewed projects including NEM projects at a number of airports.  Modeled data for runway ends entered into RealContours™ are presented in Table B‐1.  Table B‐1. Runway Data  Runway  Latitude  Longitude  Elevation (ft.  MSL)  Length (ft.)  Approach Angle  (degrees)  Displaced  Thresholds  06L  33.949108  ‐118.431154  116.6  8,925  3 ‐ 06R  33.946743  ‐118.435322  108.1  10,285  3  331  07L  33.935826  ‐118.419337  118.5  12,091  3 ‐ 07R  33.933644  ‐118.419014  119  11,095  3  ‐  24R  33.952099  ‐118.401944  117.2  8,925  3 ‐ 24L  33.950190  ‐118.401664  111.1  10,285  3  ‐  25R  33.939873  ‐118.379772  92  12,091  3  957  25L  33.937358  ‐118.382708  98  11,095  3  ‐  Source: FAA 5010 data  http://www.faa.gov/airports/airport_safety/airportdata_5010/menu/  Table B‐2 shows operations counts for modeled aircraft types, broken out by day (7:00 AM to 10:00 PM), night  (10:00 PM to 7:00 AM), and total operations. A total of 650,798 operations across 128 different aircraft types were  modeled.  Table B‐3 shows the runway utilization derived from LAX radar data, and broken out by day/night/school day and  arrival/departure. School day runway utilization (8:00 AM to 3:00 PM) is provided for comparison against daytime  runway usage.
