Astronics Corp. (Booth C2810) announced the approval of an amended supplemental type certificate (STC) for the Max-Viz 2300 enhanced vision system (EVS). The STC covers multiple Bell and Leonardo helicopter models, the latter including the AW109 and AW119. Approval was obtained in cooperation with Avio of Calgary, Canada.
The Max-Viz 2300 produces EVS images that can be presented on multifunction displays (MFDs), primary flight displays (PFDs) and on standalone displays, depending on aircraft configurations. The amendment also upgrades the wiring package to include Vivisun switches, which improve usage of night vision goggles in search and rescue, emergency medical services, aerial firefighting, and military applications.
“We worked closely with Avio to get this technology approved for daily missions on these Leonardo helicopters,” said Tom Geiger, Astronics business unit manager. “Our technology provides pilots with an unprecedented situational awareness and safety.”
Meanwhile, Astronics also announced a new, mostly solid-state CorePower frequency converter unit (FCU). “CorePower is a highly efficient unit,” said Christine Ellis, director of business development. “The goal was to not have a fan, because that leads to more mechanical failures and noise. CorePower takes variable frequency power—115-volt AC, that can be from 350 to 800 hertz—and converts it to straight 400-hertz power. This is used on special mission aircraft and some older helicopters when they need a straight-frequency power for some mission equipment. Customers can upgrade with new equipment and have the right input power.”
CorePower is smaller, wider, and lighter than the unit it replaces, Ellis said. Users of CorePower, she explained, would need “clean power, which means distortion is very low—below three volts—for critical equipment, such as running radar and sensors for military functions.” Price is in the $15,000 range.
