DVI allows the pilot to activate non-safety critical moding and data entry functions as an alternative to using manual methods.
Manual data entry
Multi-Function Head Down Display (MHDD)
Radio and navigation aids selection
Target allocation to formation members
DVI commands are confirmed by visual and/or aural feedback. This unique VTAS capability drastically reduces the pilotís workload enabling him to focus on the mission and systems operation. In an air battle scenario this system even allows the lead pilot to assign weapons to targets for both himself and his wingman with three simple voice commands.
