Avionics Update: Duncan receives multiple avionics STCs
The Citation 500 series, Challenger 600 and Falcon 2000 are the latest recipients of Duncan STCs for various avionics installations. The Lincoln, Neb.-based company recently received an STC for installation of the Honeywell GNS-XL FMS in a Citation 560. This STC, which applies to the entire Citation 500 series, was completed in conjunction with a TAWS STC. A Honeywell AFIS has also been approved for installation in the Falcon 2000, and an IS&S altimetry system was STC’d for the Challenger 600, bringing the jet closer to obtaining RVSM airspace approval.
