At the Air Traffic Control Association’s annual convention this fall, Syracuse, N.Y.-based Sensis announced that its multilateration system will replace the legacy precision runway monitor (PRM) radar used at the Sydney, Australia airport, to monitor aircraft flying simultaneous approaches to its closely spaced parallel runways, 16L and 16R.

This is an important breakthrough because, while the PRM radar increases runway throughput and reduces delays by as much as 20 percent, its high cost–said to be around $15 million per unit, uninstalled–has limited its deployment to five U.S. airports (Minneapolis/St. Paul, Philadelphia, St. Louis, San Francisco and Cleveland). The system is also deployed at Hong Kong, Frankfurt and Sydney.
