In visible moisture turn on the anti ice. During descent this is really cruical. Doesnt prevent internal icing (Cowls heated only on big engines) but restarts immedeatly when water/air mixture comes to the brink of good. Think the auto position for anti ice should be seen as last resort after slow thinking.
Maybe it just happens to me to see on TCAS, some guys fly throug CB's or very close to without thinking about the consequences.
The old days are gone when it was better using some fuel and fly the fine track around.
Just a thought.
