LINCOLN, Mass., 24 Feb. 2009. Avidyne Corp. in Lincoln, Mass., earned supplemental type certificate (STC) approval from the U.S. Federal Aviation Administration (FAA) in Washington to install the company's TWX670 tactical lightning detection system aircraft avionics in the Cessna 400 four-seat general aviation aircraft.

The TWX670 third-generation lightning-based weather detection system aviation technology provides a color-contoured display with instantaneous picture of surrounding weather. The TWX670 avionics sensor detects and displays electrical discharges -- the primary indicator of thunderstorms -- in real time, regardless of aircraft maneuvering.

The TWX670 provides tactical weather avoidance in the critical 0 to 25-nanometer range to enable the pilot to determine the areas of greatest intensity, and identify areas with potential for convective wind shear, turbulence, micro-bursts, hail, and icing. The TWX670 is for installation in helicopters and fixed-wing aircraft.

"Advanced digital signal processing and greater noise immunity allow the TWX670 to detect and display weather based on lightning and electrical activity," says Rob Higby, Avidyne's vice president of marketing, sales and service.
