When does the RAD ALT become live?
The RAs operate below 5 500 ft AGL
AUTO RANGE message appears on ND when?
The AUTO RANGE/MODE function automatically changes the ND setting to the most appropriate range and mode, in particular for specific operational situations.
In the case of W/S AHEAD or W/S AHEAD or terrain or obstacle alert, the ND automatically changes range to 10 NM and mode to ARC.

The ND displays the AUTO RANGE/MODE message.
When is the PWS function available?
If the WXR/PWS button is set to AUTO on the CONTROLS page of the MFD, and:
On ground: If the WXR is operative
During takeoff.
In flight, if the aircraft is below 1 500 ft AGL
What is the purpose of AZIMUTH knob on the
WXR?
VD AZIM KNOB When pulled, selects the manual AZIM mode. The ND displays a white line to indicate the selected azimuth value.
On the VD:
The eye symbol appears, instead of the aircraft symbol
The terrain appears along the selected azimuth.
The ND displays a straight white line based on the selected azimuth value.
When turned, adjusts the AZIM value in degrees.
The AZIM value is limited to ±60 ° around the current heading.
The VD displays the selected AZIM value in the VIEW ALONG AZIMUTH message.
The AZIM line moves on the ND, based on the flight crew’s selection
TCAS: Auto Range does what?
