MULTI-FUNCTION DISPLAY PRODUCT LINE

Project Scope

AVISTA supported our customer’s MFD product line for over 14 years, eventually taking over full responsibility for all maintenance and enhancements, including systems engineering. The MFD is fully certified and maintained to DO-178B Level A. AVISTA supported 40+ projects and certifications. The product line includes military and commercial applications, multiple fixed wing and rotary platforms. Cockpit configurations include up to 5 interconnected displays. The functionality of each display is configurable via a field loadable configuration data file.
