    Description of modification

    UNS-1Fw FMS is a fully integrated navigation and flight management system 
    installed to provide pilots with centralized control of the aircraft navigation sensors, lateral and vertical flight guidance and steering, fuel management, database management and flight planning. This modification installs a single WAAS FMS with Localizer Performance with Vertical Guidance (LPV) monitor in order to meet the integrity goals for precision approach types. LPV monitor has its own GPS/WAAS sensor which is wired and configured as a second GPS sensor with the single FMS. The key components installed on the aircraft are two GPS antenna, one FMS Navigation Control Unit (NCU), one LPV monitor, one Flight Panel Control Display Unit (FPCDU), one Solid State Data Transfer Unit (SSDTU) and eight annunciators. Depending on aircraft configurations, extra components may be needed to satisfy requirements of the new FMS integration.
