Yes I got that impression that the tilt was possibly still pointing up?

Gain on auto, tilt -0.8 manual.

While we are here, is 'Storm Ice' defined anywhere? Is it different to ice in and around CBs etc? Google only finds it via Flight Global, so have they 'invented' it?
No, it's absolutely real.

It's not simply a case of leaving your tilt below the horizon... If you don't have the latest 'virtual' scanning radars then you need to be aware that undetectable ice crystals can build up thousands of feet above the tops of CBs in IMC conditions, especially in tropical areas such as the Indian Ocean.

They cant be detected by radar hence why you need to scan well below your altitude and avoid any IMC in the levels ABOVE the tops of the CB.

Plenty of bulletins and info available from the last couple of years... will try to find some links...
