RealContours™, a pre-processor for the FAA's Integrated Noise Model (INM), is a powerful noise management and analysis tool delivering much more than just an annual contour. Where standard INM modeling techniques require human input to define representative flight paths, RealContours uses actual radar flight tracks, yielding noise contours with unparalleled precision and accuracy.
HMMH creates and maintains the RealContours/INM modeling configuration which is specifically designed for each individual airport. And as each year brings changes in airline fleet mix, runway layouts and new aircraft types, we continue to update the modeling configuration to maintain the accuracy of every contour.
RealContours always runs the very latest release of INM; it is currently supporting INM version 7.

Meeting FAA Guidelines
HMMH has developed a proprietary technique to compare radar flight track altitude profiles to all available INM standard profiles to find the best matches possible for modeling. 14 CFR Part 150, Sec. B150.3 and FAA Order 1050.1E, Par. 13b, Attachment 2, Change 4 require that a complete record of inputs to INM and the resulting log files be maintained for each INM run. By using INM standard profiles and maintaining inputs and logs, RealContours exceeds FAA's best modeling practices and computational requirements.
Real Profiles
This add-on module uses aircraft performance data to create custom profiles for radar flight tracks based on their actual profiles instead of using INM standard profiles. This serves to more accurately model the noise output of each aircraft and represents a significant advancement in the accuracy of noise prediction.
