FreeFlight introduces digital to analog convertor for radar altimeters

By General Aviation News Staff · October 30, 2020 ·

FreeFlight Systems has introduced the FDC-500 Convertor, a digital to analog convertor that allows the replacement of heavy, legacy radar altimeters with FreeFlight Systems’ RA4000/4500 radar altimeters while retaining existing antennas, cabling, and indicators onboard the aircraft.

The FDC-500 will allow the RA4000/4500 radar altimeter — which is used widely in rotorcraft and general aviation aircraft — to be installed in turboprops and small business jets, while keeping original analog panel indicators, such as the KNI 415 and KNI 416 Altitude Indicators, company officials explained.


“In continuing FreeFlight’s mission to outfit legacy aircraft with avionics for modern airspace systems, the FDC-500 is an ideal product to add to our portfolio,” says Tim Taylor, CEO and President of FreeFlight Systems. “We know there is minimal time and budget available in keeping legacy aircraft flying and FreeFlight Systems will continue to be part of the solution in keeping these aircraft airworthy.”

The FDC-500 will be available for delivery in December 2020.
