Having a calibrated-vs-current speed display in the bombsight view, the same way we get a calibrated-vs-current altitude display, would allow us to verify that we are at a constant speed.
I'd also like to see the selected bomb identifier, load count, salvo, and interval settings on the display, too, so the bombardier can verify that they've got the part of the warload they want to drop selected. Nothing is more embarrassing than taking the time to set up for a bomb run and find out that you dropped 50-kilo bombs instead of the 250-kilo bombs you intended to drop. But currently, the only place that the weapons selection is displayed is in the cockpit -- and that information should be available to the bombardier. And the salvo and interval settings aren't visible at all.
