That's certainly possible, I was looking at the picture of the Captains instrument panel taken in level cruise at FL600.
It appears as a thin red line on the face of the instrument itself opposite 190 knots
approximately.
The picture i'm referring to is on page 4 of this thread reply #66 posted by yourself !
And on further examination I think I can see what you're saying, it does look like
the lower red edge of the warning flag just visible in that window.
Thanks again BP and for the person that did the very useful indexing which made finding that picture a breeze.
