Universal FMS Support Coming to an End

December 2011

According to Service Letter (SL) No. 2843 and 2844, Universal Avionics has announced they will cease repair, support and the navigation database updates for the UNS-1M and UNS-1Msp series Navigation Management System, effective January 1, 2013. The UNS-1M has been a GPS-based navigation standard for Learjets, King Airs, Citations and other turboprop and light jet aircraft.

There are two trade-in programs Universal is offering to operators

1. Operators affected by the SL may trade-in their unit for credit toward a WAAS/SBAS-FMS.
2. Operators may trade-in their unit for a refurbished UNS-1E or UNS-1ES FMS with a one-year factory warranty that is fully upgradeable to WAAS/LPV capabilities. Because there are a limited number of UNS-1E and UNS-1Esp FMS units available from Universal, I recommend that you do not delay in taking advantage of these programs.

Duncan Aviation has a limited number of UNS-1E (or UNS-1Esp) Flight Management System units available. Installation of this system can be accomplished within one week.

For more information or to schedule your installation, contact your nearest Duncan Aviation facility.
