Boeing Business Jets said enhanced-vision system (EVS) capability is coming to the BBJ, but the technology will be offered as a retrofit both for new and in-service airplanes. In other words, buyers of new BBJs seeking to add EVS must first take delivery of their airplane before sending it to an installation center to add the EVS camera system at a cost of between $500,000 and $750,000 for the hardware alone. Approval of the Max-Viz EVS installation is expected next year and will be available through service bulletins from Boeing and HUD maker Rockwell Collins.
