Radar Validation Exercises: Personnel from ATO-P R&D's Airport Safety Technology Research program participated in radar validation exercises at Marine Corps Air Station Cherry Point in Havelock, North Carolina on April 2. The study is part of a broader collaborative effort sponsored by the US Navy to validate radar technology for use on airports to detect bird activity. As part of the validation effort, researchers set up a single radar unit in the center of the operational area of the air station for maximum coverage of the airport property. Four teams of field observers were located at different posts around the airport property. This validation protocol, commonly referred to as "ground truthing," consisted of the radar detecting targets and then the field observers confirming whether the reported target was a bird or not. Similar exercises will be conducted at Patuxent River Naval Air Station, Maryland, and Whidbey Island Naval Air Station, Washington, during the month of April. Data will be compiled and analyzed to determine not only the ability of the radar to detect and track bird targets, but as the basis for developing effective protocols for further validation. The FAA is participating as a collaborative cooperator in this effort as the objectives closely relate to similar FAA sponsored studies to develop standards for avian radar us on civil airports.

Engineered Material Arresting System (EMAS): On January 23, portions of the FAA's Engineered Material Arresting System (EMAS) environmental durability test bed were upgraded with the latest generation durability coating materials. The test bed was installed at the William J. Hughes Technical Center in May 2005 as part of a continuing effort between the FAA's Airport Technology Safety R&D Section and Engineered Systems Co. (ESCO) being carried out through a Cooperative Research and Development Agreement (CRDA). The environmental durability test bed is instrumented with over 100 sensors that provide temperature, humidity, and load data. Additional data is collected from an adjacent weather station. Project engineers have been monitoring the bed for about 20 months and are hopeful that the data may yield important insight into material response to environmental condition changes and lead to predictive trends for long term durability forecasts. This recent modification of the test bed included the removal and replacement of ten of the 150 blocks of cellular cement material. New joint sealants and protective side protection materials were also installed. The FAA's test bed now contains various versions of arrestor bed composition representative of those that are installed at nearly 20 airports across the United States.
