SCN 1002.3


Upgrade your UNS-1Ew FMS units to SCN 1002.3 or greater with Flightstar STC #ST04522CH.

SCN 1002.3 can be completed on a single UNS-1Ew with LPV Monitor or with dual UNS-1Ew FMS units. It corrects or adds the following:

  • Corrects known VNAV pitch issue. This issue is discussed in the Bombardier Advisory wire, AW22-009 titled “Pitch Oscillation During Approach”. This known issue occurs during the final approach segment of LPV and LNAV/VNAV approaches when using UNS-1Ew FMS units in the Learjet 40 and 45.

  • Adds Localizer Performance approach capabilities.

  • Adds Push-to-Load en route functionality to aircraft previously equipped with CPDLC. This function allows for the automatic loading of information received from Air Traffic Control via Controller-Pilot Data Link Communications (CPDLC) into the FMS flight plan.

Receive use of this STC free of charge when purchasing Flightstar STC #ST04421CH, CPDLC DCL, ATN B1 CPDLC, and FANS 1/A+.
