SBAS-FMS SCN 1002.1/1102.1 Released

Apr 18, 2019

NextGen FMS Family

Universal Avionics introduces Software Control Number (SCN) 1002.1/1102.1/1102.1M for the Satellite-Based Augmentation System-Flight Management System (SBAS-FMS). The following updates were accomplished in the new software version:

Future Air Navigation System (FANS) / Controller-Pilot Data Link Communications (CPDLC) Push-To-Load
Software now supports route clearance uplinks and downlinks, including automatic flight plan updates from Air Traffic Control (ATC) messages, requests to ATC for flight plan changes, and reports of the flight plan to ATC. This functionality allows flight plan data from the UniLink™ UL-800/801 Communications Management Unit (CMU) to be reviewed and used by the crew to update the active flight plan. In addition, flight plan data and ATC requests can be sent from the FMS to ATC via the UniLink CMU. Note, this change renames any reference from “UniLink RTE” to “Dispatch RTE” to avoid confusion between routes received from ATC and routes received from the airline dispatch.

GLS-1250 Sensor Selection
This minor point change includes a functionality which modifies the logic used in selecting the master GPS sensor for a navigation solution. Previously, the GLS sensor had priority over the SBAS GPS sensor. This change results in the SBAS GPS sensor having higher priority except when conducting a GLS approach within 30NM of the destination.

Transition-To-Hover Guidance
This software displays a new guidance waypoint, “TDN,” on an Electronic Flight Instrument System (EFIS) when Transition-To-Hover is active. It will also display wind angle in magnetic on page NAV 1 when Transition-To-Hover is active and magnetic variation is valid. This software update also adds a new configurable Transition-To-Hover install type CDV155_REV1 to render a more accurate final hover position when the helicopter descends from high altitude with high vertical speed. This change optimizes the Transition-To-Hover pattern size to reduce the time from Mark-On-Target to hover position and also minimizes the track error while capturing Transition-To-Hover RF leg.
