AFMS, GARMIN G500 PFD/MFD SYSTEM 190-01102-01 Rev. 9FAA APPROVED Page 12 of 401.6 Audio PanelThe G500 PFD/MFD system should be interfaced into the aircraft audio panel toprovide aural altering generated by the G500 (required for SVT installations).1.7 Traffic and Weather SystemsThe G500 PFD/MFD system supports TIS traffic via the Garmin GTX SeriesMode-S Transponders. The system also supports TAS/TCAS/TIS traffic fromvarious active traffic awareness systems. The information from these systems isavailable and controllable on the MFD.The G500 PFD/MFD system supports XM datalink weather via the GarminGDL69 and GDL69A receivers. If an optional XM datalink receiver is installed,the pilot will be able to access graphical and text weather products on the MFDand control the audio entertainment data from the MFD while listening via anappropriately installed audio panel.Datalink weather is also available via the Garmin GSR 56 Iridium Transceiver.The control and display of Iridium satellite weather on the MFD is similar toXM weather.Control and display of various airborne weather radars is optionally available onthe MFD. The G500 supports Garmin GWX weather radar, as well as certain3rd-party weather radars.1.8 Video sourcesThe G500 Avionics Display System can display images from up to 2 videoinputs. Video images are displayed on the MFD. The G500 does not provide ameans to control the video source; however the digital images from the videosource can be adjusted using the G500.1.9 Radar AltimeterThe G500 supports the display of radar altitude on the PFD from supportedradar altimeters.1.10 High Speed Data Bus InterfaceSome Garmin equipment connected to the G500 system utilizes the High SpeedData Bus (HSDB) interface. HSDB is similar to an Ethernet bus and provides ahigh-speed interface between Garmin avionics. Like Ethernet, data between twounits may be passed through intermediate “hub” units. Interfaced equipmentthat uses HSDB includes the GTN 6XX/7XX navigators, GDL 69 datalinkreceiver, GWX 68, and GTS 8XX traffic systems.The HSDB interfaces are installed to so that maximum data path redundancy isachieved. However, depending on the number of HSDB units installed, failureof one HSDB unit may result in loss of data on the G500 from “downstream”HSDB units. Any loss of data will be annunciated on the G500.
