india you do get an effect that the pilot begins to think that there is something wrong with automatics.
It can be cloud top slant, fog bank on water or a distance effect on the horizon.
When a FO first gets it you have to go through checking the instruments and all the other toys. Some are sure they are in a turn and climbing/descending and would be quite happy to pop the AP out and make it look right. Takes a change in faith and instrument discipline before they become comfortable with seeing the effect and double checking its a visual error.
