Joe,
One other thought. Have you seen the NASCAR gages that have back-lighting that changes with conditions -- green for normal operating range, yellow for adverse trend, red for out of parameter, and flashing red as an attention-getter for things that are really bad? You could probably do something like that on a color flat panel, with perhaps an audio warning or a flashing "check gages" light on the hud to call your attention to a problem.
