RealProfiles, a software module within HMMH's RealContours system, calculates aircraft speed, altitude, track distance, and thrust based on radar data, local weather condtions, and INM aircraft parameters. This information, based on the actual flight path of the aircraft, allows calculation of aircraft noise with greater accuracy compared to using the pre-determined flight paths found in the standard INM.
The system is currently installed in the Sacramento County Airport System Airport Noise and Operations Monitoring System (ANOMS).
