AFMS, GARMIN G500 PFD/MFD SYSTEM 190-01102-01 Rev. 9FAA APPROVED Page 20 of 40Not all autopilot systems are approved for GPS vertical coupling; thereforeconsult the AFMS for the GPS/SBAS system and/or the autopilot system.Flight director commands on PFD 2 are repeated from PFD 1. When utilizingthe flight director display on PFD 2, ensure that the CDI source and BAROsettings on PFD 2 match those on PFD 1.For installations where the GAD 43 provides attitude information to theautopilot, the GAD 43 autopilot disconnect mechanism must be tested andoperational before flight using the autopilot. Refer to Section 4.6.9.2.15 Terrain Proximity FunctionThe G500 terrain configuration is indicated on the dedicated terrain page of theMAP group. “TERRAIN PROXIMITY” will be displayed as the page title ifthis function is configured. The G500 terrain and obstacle information appearson the MFD display as red and yellow tiles or towers, and is depicted foradvisory only. Aircraft maneuvers and navigation must not be predicated uponthe use of the terrain display. Terrain unit alerts are advisory only and are notequivalent to warnings provided by TAWS.2.16 TAWS Annunciations on the PFD [from a Garmin navigator]The G500 can display TAWS (Terrain Awareness and Warning System)annunciations on the PFD if the G500 is interfaced to a Garmin navigator withintegrated TAWS. The required TAWS annunciations appear in the upper rightof the PFD. These annunciations include PULL UP (red), TERRAIN (yellow),TERR N/A (white), TERR INHB (white). These annunciations are not relativeto the terrain displayed on the MFD or the yellow/red terrain shading of theSynthetic Vision displayed on the PFD of the G500 system. Refer to the Garminnavigator Airplane Flight Manual Supplement for proper pilot action andinformation on these alerts.TAWS alerts on the PFD of the G500 System are only displayed from theGPS/TAWS navigator interfaced as GPS 1 and are displayed regardless of thesystem 1-2 setting, which drives all other PFD and MFD data used by the G500.2.17 Datalinked Weather Display (XM or GFDS weather)Datalink weather data is provided by an optional GDL 69 (XM) or GSR 56(GFDS) interface. The weather information display on the MFD of the G500 islimited to supplemental use only and may not be used in lieu of an officialweather data source. Use of the datalink weather display for hazardous weather(e.g thunderstorm) penetration is prohibited. The datalink weather display isintended for use as an aid to situational awareness only.2.18 Traffic DisplayTraffic may be displayed on the G500 System when connected to an approvedoptional TCAS, TAS, or TIS traffic device. These systems are capable ofproviding traffic monitoring and alerting to the pilot. Traffic shown on thedisplay may or may not have traffic alerting available. The display of traffic isan aid to visual acquisition and may not be utilized for aircraft maneuvering.
