At SWA we have round dials presented on our EFIS airplane displays. It was originally done for commonality with the steam fleet. Since that time, there have been studies to show that analog needles in a round display, even if they are EFIS generated, are more intuitive and have quicker recognition of problems than tape or digital depictions. On an airspeed indicator, for example, you know just by "clock face" depiction where your critical or common speeds are roughly even if the numbers were removed. It is also amazing how a needle based engine gauge out of whack can be detected just by peripheral vision even in a sea of other gauges.
I like the other things that can be overlaid on the depiction, but I also like the round dial concept, even in an EFIS display.
Didn't see Bubblehead's post until posting mine. Our minds are in the same gutter!
