just to operate the WX radar as optimal as possible, Airbus recommends the following (manual) tilt adjustments:
negative tilt to keep ground returns on top of ND
the following settings to keep ground returns on top of ND ...
Range 320: 1 DN
Range 160: 1.5 DN
Range 80: 3.5 DN
- Range 40: 6 DN
- Below FL150 - Every 5 000 ft: Adjust tilt upward to maintain ground returns on top of ND (~ +1°/5.000 ft)
- Approach: 4° UP
At that point, I was trying to figure out any WX's logic behind the auto-tilt function ... is there any pre-set schedule or formula used by WX to work the auto-setting out ?
What requirements apply in turning the GCS (Ground Clutter Suppress) ON ? As far as I know it has to be selected ON to avoid unwanted ground returns associated with high negative tilt angles ...
Thanks in advance,
