Addison Airport Joins Radar Network to Improve Hazardous Weather Forecasts

April 7, 2014

ads coverage mapAddison is part of a five-year, $10 million project to demonstrate how a radar network of X-band sensors can improve hazardous weather forecasts, warnings, and responses in a dense urban environment. The Dallas Fort Worth Urban Demonstration Network consist of eight radar sites, including the Town of Addison Service Center on Westgrove Drive, at the northeast corner of Addison Airport.

The Center for Collaborative Adaptive Sensing of the Atmosphere (CASA) and the North Central Texas Council of Governments (NCTCOG) are leading the project. It will develop high-resolution radar maps of current and future weather in the lowest part of the atmosphere, altitudes unseen by other weather radar. This overlapping network will detect and forecast severe wind, tornadoes, hail, ice, and flash floods.


Equivalent Numbers Give a New Perspective on Taxiway Alpha Project

March 24, 2014

AlphaLooking at Addison Airport with an aviation perspective, compared to the parallel 100-foot-wide Runway 15/33, Taxiway Alpha is a narrow strip of pavement, so improving it shouldn’t take much time, right? Now that the project is complete, Mitchell McAnally, an engineer with Garver USA who was the project’s manager, put the effort in its proper contest by sharing the numbers in equivalent terms.

The project reconstructed 54,000 square yards of Taxiway Alpha. Put another away, that would build 1.25 miles of full-width Belt Line Road, from Midway to the Town of Addison City Hall. It consumed 30,500 tons of asphalt, and if it were delivered at one time, the line of trucks, bumper to bumper, would stretch from the airport to the American Airlines Center in downtown Dallas.

Concrete aircraft holding bays were constructed at both ends of Taxiway Alpha. The north bay is 35-percent larger than its predecessor, and the south bay now gives aircraft an area to perform their run-up checks without blocking the Taxiway Alpha traffic flow. In five days last August, the project rebuilt 800 feet of Taxiway Tango and continued the asphalt overlay over its remaining length.

N AlphaCrews stretched 84,140 linear feet—15.93 miles—of cable and conduit along Taxiway Alpha to power and control the 376 LED taxiway edge lights that replaced 288 incandescent lights. While the number of individual lights increased nearly 25 percent, the overall power needed to make them glow dropped by 40 percent compared to the previous incandescent needs. That doesn’t include the power going to the 58 new LED taxiway position and guidance signs, which are larger than the 52 incandescent signs they replaced.
