West Star Adds EVS to Challenger 604

West Star Aviation announced the completion of flight testing in a customer Challenger 604 of a Kollsman enhanced-vision system at the company’s Grand Junction, Colo. modification center. Incorporating a streamlined, low-profile fairing on the Challenger’s upper nose, the Kollsman EVS-II external camera will be integrated with the new Kollsman AT-HUD and operationally certified, making the complete system eligible for landing credit to 100 feet on straight-in precision approaches.

Known as an enhanced flight vision system (EFVS), the system is claimed to be the first ever, non-OEM aftermarket EVS displayed on a HUD. Working with a team of partners that included EVS equipment supplier Elbit Systems of America (Kollsman Commercial Aviation) and various subcontractors, West Star Aviation’s certification effort involved “computational fluid dynamics, fairing, substructure and EVS window functionality, required conformity and detailed flight testing,” according to the company. An STC for the installation is expected to be issued this month. The EVS-II camera is identical to those being installed as standard equipment on new large-cabin Gulfstream business jets, FedEx airplanes and offered as optional equipment on the Embraer Lineage 1000 bizliner.
