Kollsman Avionics, which worked with Gulfstream to develop the first certificated enhanced vision system (EVS), has begun offering the system to other manufacturers. The system is being marketed as the All Weather Window. A simplified Night Window is being developed for smaller business jets.
The Kollsman EVS was certificated on the Gulfstream V last year and entered service earlier this year on a GV delivered to the US Air Force. Work is under way to certificate the system on the GIV by year-end, says Kollsman. The agreement with Gulfstream prevents it offering the system to certain aircraft manufacturers, but talks are under way with others, Kollsman says. The EVS is compatible with any raster-capable head-up display.
The All Weather Window uses a broadband camera that operates in near and mid-wave infrared (IR) and can detect runway lights and ground features, allowing lower approach mimina, but the Night Window system uses a long-wave IR camera and is intended to provide awareness of surrounding terrain during clear night operations. The system does not provide lower approach minima, Kollsman says. The Night Window should be available next year.
