COMPLIANCE
 Optional

PURPOSE
 GNS 400W/500W Series Main Software v5.40 includes the following:

• Added support for GFC™ 500 Flight Control System.

GNS WAAS Main Software Version 5.30

COMPLIANCE
 Optional

PURPOSE
 GNS 400W/500W Series main software version 5.30 includes the following changes:

• Added support for using the GDL® 88 Data Transceiver heading input as a source of system heading.
• Corrected an issue, when configured with a GDL 88 with TCAS and no heading source, with ADS OFF and TCAS ON, the traffic page would incorrectly annunciate traffic as TRK (track up) rather than HDG (heading up).
• Corrected an issue where the TOTAL TRIP TIMER would set to zero upon takeoff if the DEPARTURE TIMER criteria is set for IN AIR.
• Corrected the 'GDL 88 Traffic Alerting has failed' system message to ‘GDL 88 Traffic Alerting Not Available.’
• Expanded the display bounding box for Non-CONUS METARs sent from the GDL 69/69A to include western Alaska and Hawaii.
• Corrected an issue where the GNS did not show the GDL 88 traffic test pattern on the NAV TRAFFIC page.

GNS WAAS Main Software Version 5.20

COMPLIANCE
 Optional

PURPOSE
 GNS 400W/500W Series main software version 5.20 includes the following changes:

• Added support for Garmin Flight Stream 210, providing data including flight plan (input/output) and GPS position to mobile devices over Bluetooth.
• Added support for the Vivisun tri-state HTAWS external annunciator to differentiate between the “HTAWS N/A” and “Pilot Inhibit” annunciations.
• Adjusted the width of the HTAWS Reduced Protection mode search volume to reduce nuisance alerts.
• Changed the behavior of the GDL 88 Traffic page on helicopter configurations so that the display becomes unavailable—ADS traffic targets are not displayed—when heading is invalid and ground speed is below 15 knots.
• Resolved an issue affecting the Fuel On Board setting for configurations where fuel flow is provided by an external device but Fuel On Board is not.

GNS WAAS Main Software Version 5.10

COMPLIANCE
 Recommended

PURPOSE
 GNS 400W/500W Series Main Software version 5.10 includes the following changes:

• Added support for advisory vertical guidance for LP approaches (LP+V).
• Added support for displaying ADS-B traffic on the Navigation Map page when no heading source is installed or valid.
• Increased the maximum range on the Traffic page to 24 NM to support the GTS 800.
• Resolved an issue with the lateral CDI scaling as described in Service Advisory 1344, “LPV and LNAV/VNAV Approach Full Scale Deflection.”
• Resolved an issue with approaches with a glide slope of zero as described in Service Advisory 1372 “Unavailable RNAV (GPS) approaches due to lack of VDA.”
• Resolved an issue where the CDI could indicate cross-track error on the opposite side of the course when a turn was active and the cross-track was very large. This corrects the issue described in Service Advisory 1352, “Incorrect Course During Turn Transition.”
• Resolved an issue where under some circumstances locked waypoints within stored flight plans did not remain locked as intended. This corrects the issue described in Service Advisory 1363 “User-modified terminal procedure stored in Flight Plan may cause error condition.”
• Resolved an issue where changing one map setting on the Map Setup page could change other map settings.
• For units connected to GDL 88 units:
  • Suppressed the “Traffic device has failed” alert message during the time when the GDL 88 reports that its GPS is initializing.
  • Modified the text of the “Pressure altitude input fault and TAS/TCAS input fault” messages to describe the specific problem, rather than “GDL 88 service required.”
  • Suppressed the “ADS-B transmit fail” message when the GDL 88 is not configured to transmit ADS-B data.
  • Removed the GDL88 traffic test pattern from the Navigation Map page (leaving it on the Traffic page).
• Resolved an issue where traffic targets could be selected when panning across the NAV map even though the traffic overlay was not being displayed on the NAV map

GNS WAAS Main Software Version 5.03

COMPLIANCE

Fixed Wing Aircraft installations:

Recommended for all installations with GNS 400W/500W installed with Main software version 5.00 (non-warranty)

Optional for all other GNS 400W/500W installations (non-warranty)

Rotorcraft with Garmin HTAWS previously installed:

Mandatory for all installations with GNS 400W/500W HTAWS installed (warranty)

Optional for all other GNS 400W/500W installations (non-warranty)

PURPOSE

This Service Bulletin announces the availability of new GNS 400W/500W Series Units Main Software version 5.03 and GPS/WAAS Software version 5.0.

GNS 400W/500W Series Main Software version 5.03 includes all of the following capabilities and features that were incorporated into Software version 5.00:

• Added support for GTN™ avionics crossfill (i.e., the sharing of user waypoints and transferring the active flight plan from a GTN to a GNS).
• Added support for use of the GNS 400W/500W as a position source for the GDL 88 ADS-B Datalink Transceiver.
• Added support for display of FIS-B from the GDL 88 ADS-B Datalink Transceiver.
• Added support for AC 20-165-compliant ADS-B Out operation of the GTX 330 ES transponder when the GNS unit is used as a position source. This addresses SA 1215.
• Added support for Canadian METARs and TAFs when available in the SXM Weather package provided by the GDL 69.
• Increased the software design assurance level for the Terrain page maps to Level C. Main Software version 5.00 meets TSO-C194 for HTAWS. This addresses IB 1159.
• The Procedures page now hides LNAV/VNAV-only approaches that are not authorized for SBAS.
• Corrected the issue where the text for SXM METARs and TAFs was not being displayed for some airports with three-character identifiers. This issue only occurred in situations where a 'K' identifier and a non-'K' identifier are associated with different airports, such as K1A5 and 1A5.
• Corrected issues with plotting Stormscope lightning strikes in incorrect locations in certain situations. This addresses SA 1146.
• The waypoint field on the RAIM Prediction page has been changed to default to the destination airport.
• Added a new Configuration page to allow TAWS Airport Criteria to be specified. This option allows an installer to remove from consideration in the TAWS algorithms airports that can't be used by the aircraft.
• Increased the maximum number of waypoints in a Flight Plan Route from 31 to 100.
• Added additional checks to the GNS-to-GNS crossfill interface to assure data is provided by a valid source. This change may affect the operation of non-Garmin equipment using this interface.
• GNS 400W/500W Series Main Software version 5.03 added support for use of the GNS 400W/500W as an ADS-B traffic display for the GDL 88 UAT Datalink Transceiver.
• Corrected the issue, addressed in SA 1047 and IB 1048, in which CDI (Course Deviation Indicator)/HSI (Horizontal Situation Indicator) scaling on a limited number of LNAV/VNAV and LNAV+V approaches was incorrect. The affected LNAV/VNAV and LNAV+V approaches, which have been selectable as LNAV-only approaches in the interim, can now be selected as LNAV/VNAV or LNAV+V.

In addition, GNS 400W/500W Series Main Software version 5.03 also includes all of the changes described in SSB 1006 for Main Software version 4.01.

GPS/WAAS Software version 5.0 contains the following change:

• Added support for the AC20-165-compliant ADS-B position outputs for the GDL 88 UAT and the GTX 330 ES Transponder (with compatible versions of GTX software).
• For additional information related to the GNS 400W/500W software, refer to STC Service Bulletin No. 1315 Rev A or later.
