Max-Viz said an STC approval for its EVS-1500 enhanced vision system in Hawker business jets is close at hand. According to the avionics company, Hawker Beechcraft Global Customer Support’s program for installation of the EVS-1500 on Hawker 750s, 800s, 850s and 900s will be STC’d by next month. Installations through Hawker Beechcraft Services’ factory-owned service centers will require three to four days of downtime, Max-Viz told AIN. The EVS-1500 will also be a factory option on new 900XPs.
