The left screen that looks like WX radar is actually the EGPWS map display, which shows the terrain below in colors according to its relative elevation. The terrain is rotated so that it is always course-up, thus it is easy to "see" in your mind's eye relative to your path. If terrain or obstructions are a potential threat, they are yellow, and if at or above current altitude, they are colored red. This is also true for any towers, rigs or stuff that is on the data base, as well as anything that operations puts on the data base (like temporary cranes, rigs or wires.) As well, if you wander toward a red thing, as you get closer, an aural warning calls out warnings. If you are in a turn, and your turn radius will end up within a red thing, you also get a warning, as will a descent. It is therefore reasonably smart.

All in all, it is pretty scarey, zeebeedee, Helicomparitor and sox6, I too would rather NOT have it and would rather feel comfort in the blankness of the EGPWS-less screens! A Rad Alt bug is MUCH more informative, and AVADS is the absolute BEST! Until it is made absolutely perfect, and shows satellites above, and submarines below the surface,it is not desirable.
