Pro Star Aviation ODA Issues FAA Approval a Transport Category First; Universal FMS Software Update

April 14, 2017

Londonderry, NH (April 14, 2017) - Pro Star Aviation has received FAA approval from its in house STC ODA for the amendment to STC ST00158BO to add software version SCN 1001.X to a Single Universal Avionics Systems Corporation (UASC) UNS-1Espw with LPV Monitor or dual UASC UNS-1Lw Flight Management Systems (FMS) on Cessna Citations equipped with Honeywell P-1000.

The newly amended STC currently applies to Cessna aircraft models; 550, 550 Bravo, 560, 560XL and 560XLS Series. This STC can be purchased by contacting either Pro Star Aviation directly or your nearest UASC authorized dealer.

Old SCN S/W Version number (Pre-Mod)

New SCN 1001.X S/W Version (Post-Mod)


Upgrading Software Control Number (SCN) 1001 requires a new airworthiness approval as this is a major change to the FMS. The Upgrade must be accomplished at the factory for existing WAAS installations or as part of a new WAAS FMS installation. SCN 1001 is the most current FMS operation software and offers the following enhancements over previously approved versions of Universal FMS software; Enhanced User Interface, Upgraded Comm Radio Tuning, Improved Lateral Guidance/Steering, Upgraded Precision Approach (SBAS) and Non-Precision Approach performance, as well as newly revised Maintenance and Configuration sections. In addition, SCN 1001 will also offer enhanced ADS-B functionality.

Regarding the software upgrade, Jeffrey Shaw, Director of Business and Development states,

"This software change offers the latest operational upgrade to one of the most successful and well liked standalone Flight Management Systems in the Business Aircraft Marketplace. In addition to several user interface and performance improvements, the new SCN level offers enhanced ADS-B integration for the looming NextGen mandates of 2020.”


Any Authorized Universal Avionics Systems Dealers, like Pro Star Aviation, are authorized to perform this upgrade. For an added convenience, Pro Star’s installation teams can perform this service on-site in Londonderry, NH or off-site at an operator’s home facility via their ON-THE-FLY Service option.

Additionally, in complement to ST00158BO’s amendment, Pro Star has two AML STC’s available for purchase which utilize the UNS-1()w FMS as an approved position source; ST00373BO and ST00361BO. ST00373BO is approved to pair a Rockwell Collins ADS-B Out capable TDR-94D Transponder(s) to the UASC UNS-1()w FMS. ST00361BO, currently pending amendment approval (expected mid-March), authorizes the pairing of a Honeywell Primus II (XS-852) ADS-B Out system to the UASC UNS-1()w FMS.
