The GDL 69A is the same as the GDL 69with the addition of an Sirius XM Satellite Radio audio entertainment receiver.Weather data and control of audio channel and volume is displayed on the MFD,via a High-Speed Data Bus (HSDB) Ethernet connection. The GDL 69A is alsointerfaced to an audio panel for distribution of the audio signal. A subscriptionto the Sirius XM Satellite Radio service is required to enable the GDL 69/69Acapability.Subscription information is available at: http://www.garmin.com/xm/.Figure 1-9 GDL 69/69A XM Satellite Radio Data Link Receiver1.1.10 GAD 43(e) (Optional)The GAD 43 is an adapter that converts AHRS digital pitch, roll, headingand yaw rate data into analog signals used by autopilot systems. The GAD 43is installed remotely between the AHRS and an existing autopilot. The analogsignals from the GAD 43 mimic those of spinning-mass gyros that provide datato the autopilot and allow the gyro to be replaced by the AHRS and GAD 43combination.The GAD 43e performs the same functions as the GAD 43, but adds supportfor additional interfaces to various aircraft systems. The GAD 43e supportsinterfaces to various autopilots (for altitude preselect and vertical speed control),analog NAV radios, DME, analog radar altimeters, marker beacons, and ADFreceivers.
