Seattle-Tacoma International Airport Purchases PASSURSoftware

GREENWICH, Conn., Nov. 3 /PRNewswire-FirstCall/ -- Megadata Corporation (OTC Bulletin Board: MDTA) announced today that Seattle-Tacoma International Airport (Sea-Tac) has purchased a subscription to PASSUR(R) FlightPerform(TM) to improve overall operations.

"Airports are taking on greater responsibilities in flight operations, and as they do, our proven operational tools - like FlightPerform - are becoming more critical to them," said Jim Barry, Megadata's President & CEO. "We are very impressed with the Ramp Tower Controllers at Sea-Tac and we're looking forward to their suggestions for further enhancements to our capabilities. This is our first opportunity to work with Sea-Tac, and we're pleased we can play a part in their bright future."

FlightPerform is the industry "gold standard" for airspace visualization, for those customers who need the most dependable, reliable capability to guide their operations in real time. FlightPerform is a live flight and airspace analysis and awareness system using air traffic management-style displays and tools, used by airports and airlines for real-time arrivals, dispatch and facilities management.

"We picked FlightPerform largely on the basis of its frequent refresh time," said Mike Ehl, director of operations at Sea-Tac. "We felt the frequent updates of the on-screen data gives us an additional measure of safety and efficiency."
