AlliedSignal runway system gets final OK from FAA Transponder contract with Britain also is announced

September 04, 1996|By Greg Schneider | Greg Schneider,SUN STAFF

AlliedSignal Aerospace had a busy day yesterday at the Farnborough Air Show in England, announcing a pair of developments that benefit its Communications Systems operation in Towson.

A precision runway monitor system developed at the Joppa Road facility won final acceptance from the Federal Aviation Administration for use at the Minneapolis-St. Paul Airport.

And the British military agreed to purchase customized friend-or-foe identification transponders for certain long-range support helicopters.

The runway monitor system is the only federally certified method for air traffic controllers to land planes on parallel runways. A prototype was installed at an airport in North Carolina, but the Minnesota system is the first of five full-fledged production units in the works.

The others are planned for airports in New York, St. Louis, Philadelphia and Atlanta.

A similar system produced for the Kingsford Smith Airport in Sydney, Australia, also received final acceptance yesterday, from that country's oversight agency.

The system uses a radar that scans quickly and updates each aircraft's position and velocity every second, giving controllers time to coordinate parallel approaches.

The helicopter contract was hailed by AlliedSignal as an entree into the European market. The company's APX-100 transponder, produced in Towson, receives friend-or-foe interrogation signals and transmits a reply identifying the aircraft. The British military plans to use them on SH-101 helicopters.

AlliedSignal Inc. declined to disclose the value of the contract.

The company has headquarters in Morristown, N.J., and employs almost 1,000 at its facility in Towson.

Another 3,000 work at the company's Technical Services division in Columbia.
