Weather Radar Tilt Calibration
Any ideas how the wx radar tilt calibration is checked to be correct(i.e. the tilt shown on the ND corresponds to the actual antenna tilt) by the avionics guys since I have often wondered when flying around on A330/340s that the tilt is so obviously out i.e. the ND is showing a tilt 3.0 down or more(over land) & no returns. As always filled out in the Tech log but engineering do a ground check &, surprise surprise it's ok but then fly the same A/C & the problem is still there.
