Foreword System Sec 1 PFD Sec 2 MFD Sec 3 1.1.8 GDL 69/69A (Optional) The GDL 69/69A is an XM Satellite Radio Data Link Receiver that receives broadcast weather data. The GDL 69A is the same as the GDL 69 with the addition of an XM Satellite Radio audio entertainment receiver. Weather data and control of audio channel and volume is displayed on the MFD, via a HighSpeed Data Bus (HSDB) Ethernet connection. The GDL 69A is also interfaced to an audio panel for distribution of the audio signal. A subscription to the XM Satellite Radio service is required to enable the GDL 69/69A capability. Figure 1-8 GDL 69/69A XM Satellite Radio Data Link Receiver 1.1.9 GAD 43 (Optional) The GAD 43 is an adapter that converts AHRS digital pitch, roll, heading and yaw rate data into analog signals used by autopilot systems. The GAD 43 is installed remotely between the AHRS and an existing autopilot. The analog signals from the GAD 43 mimic those of spinning-mass gyros that provide attitude data to the autopilot and allow the gyro to be replaced by the AHRS and GAD 43 combination.
