MADRID,  Feb. 12, 2013  /PRNewswire/ -- The U.S. Federal Aviation Administration
(FAA) has applied hundreds of thousands of research measurements made by
Lockheed Martin's [NYSE: LMT] WindTracer®  Doppler lidar to redefine flight
rules, achieving major efficiency enhancements at U.S. airports.  

The FAA granted approval for  San Francisco  International Airport (SFO) and
Newark Liberty International Airport (EWR) to conduct dependent arrival
operations on their closely spaced parallel runway (CSPR) pairs. SFO and EWR
have joined a growing list of airports with CSPR geometries that are authorized
by the Federal Aviation Administration to conduct a wake turbulence mitigation
procedure for CSPR operation, known as FAA Order JO 7110.308 - Ch3. The safety
assessment is enabled with significant amount of wake measurement research using
WindTracer lidars.    

The assessment permits reduced diagonal spacing of 1.5 nautical miles on
adjacent runways relative to the leading large- and small-category aircraft with
runway spacing less than 2500 feet under Instrument Flight Rules. Before the
implementation of 7110.308, planes arriving on two such CSPRs were required to
be spaced as if they were using a single runway, which effectively closed down
one of the parallel runways under instrument conditions. This procedure at SFO
and EWR is expected to reduce delays significantly.  

"We are thrilled that the FAA has employed our WindTracer Doppler lidars to
achieve these critical improvements to U.S. air traffic rules," said Dr. 
Michael Margulis, director of WindTracer Programs at Lockheed Martin. "These
changes will greatly increase U.S. civil airspace capacity while maintaining the
highest standards of air traffic safety."

The FAA Wake Turbulence Research Program has been using WindTracer systems since
2001 at multiple airport locations to conduct wake turbulence research
measurements. The databases are carefully mined to provide data-driven
assessment of ongoing and future wake turbulence mitigation concepts. In
addition, wind data collection is also used to develop weather-based wake
mitigation solutions.

The John A. Volpe National Transportation Systems Center, part of the U.S.
Department of Transportation's Research and Innovative Technology
Administration, maintains and operates a fleet of WindTracers for the FAA Wake
Turbulence Research Program and provides data analysis and other resource
