Sensis Hopes To Deploy Three More By Mid Year, 2011
Thirty-two major U.S. airports are now operating with Sensis
Corporation's Airport Surface Detection Equipment, Model X
(ASDE-X). ASDE-X is the FAA's key runway incursion detection and
alerting program set to be deployed to a total of 35 airports by
mid-2011. The technology provides air traffic controllers,
including those at five of the 10 busiest airports in the world,
with precise surveillance of aircraft and vehicles on the runways
and taxiways. ASDE-X also incorporates advanced conflict detection
and alerting capability to provide controllers with automatic
visual and audible warning of potential incursions.
The company says that, as the FAA's primary runway safety tool,
ASDE-X has made a positive impact in the reduction of runway
incursions, including a 50 percent reduction in serious incursions
for the FAA's last two fiscal years, from October 2008 through
September 2010. Earlier this year, the NTSB released its updated
"Most Wanted List - Transportation Safety Improvements," which
upgraded the status of its runway safety recommendations. In
response to the updated list, the FAA noted that the deployment of
ASDE-X and Runway Status Lights (RWSL), also being deployed by
Sensis, are addressing the NTSB's recommendation to "give immediate
warnings of probable collisions/incursions directly to flight crews
in the cockpit."
ASDE-X combines surface movement radar, multilateration and
Automatic Dependent Surveillance - Broadcast (ADS-B) surveillance
to provide air traffic controllers with highly accurate, real-time
position and identification information of aircraft and vehicles on
the airport surface. By integrating multiple surveillance
technologies, the system delivers a comprehensive picture of ground
operations, increasing controller situational awareness and
improving airport safety in all weather conditions. The system also
features advanced runway conflict detection and alerting
technology, Safety Logic, which uses complex algorithms to alert
controllers of potential aircraft or vehicle incursions. Further,
ASDE-X is serving as the surveillance infrastructure for the FAA's
RWSL program.
Sensis says that ASDE-X also facilitates the sharing of surface
surveillance information through data distribution. In the Radio
Technical Commission for Aeronautics (RTCA) NextGen Mid-Term
Implementation Plan, the organization recommended that surface
situational awareness of the runways, taxiways and ramp areas,
obtained through a system such as ASDE-X, be shared among airport
stakeholders to create a more efficient airport surface management
environment. The FAA identified in its response to the Plan a
number of actions to enhance surface movement activity through
shared situational awareness of surface activity.
