Please don't think for on minute I'm in agreement with casa over this. Just trying to find out what you see. As with most things in aviation excepting airbus on this. Movement is the main trigger that's why the master lights flash. Also that's why Boeing use a control colum for triggering movement in the systems. A light is a light. Is there a difference between two colours. By that I mean if one is what a normal person would see as red and orange do you see them as different shades or the same as each other.
I've go to say I find glass screens hard to read. Pro line 21 much easier than the garmins.
Yeap I agree that we would be seeing accidents if this was such an issue.
Also it goes against the human factors that they push so hard for.
Cheers
