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 High-
Speed 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.

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.
