Not sure what the utility of replicating extant information is.
Were it something additional and useful then I think you'd have a case. But currently it's needless replication.
Dave, your case is also flawed; modern fighter aircraft HUDs all show replicated extant information. Altitude, IAS, Heading, pitch, AoA are all displayed elsewhere in the cockpit.
Hitsuke's request is reasonable. although FD has opted for a sparse, futuristic 'look' yet thoroughly disabled cockpit interface... there's hardly any actual Heads-up display at all. Selected weapon. A sort of "I'm going that way" circle. Two outer brackets that serve little purpose. There's not even a nose/heading caret, something several actual pilots have commented on (yes I know you can enable a small yellow dot but c'mon, really?).
Google Independence War 2 for a decent example of a non-cluttered reticle-based HUD UI. Clean, clear and doesn't get in the way.
FD can do
far better; I am sure any actual human UI designer (i.e. not a gamer, not a game UI designer) will sit back and say FD's UI is... well... rubbish. It is. Look at it. Its gorgeous (don't get me wrong, I love it) but its well below par on functionality, ease of use and controls that should be to hand for a air/space craft pilot.... aren't. Its not dynamic based on situational context (something modern HUDS are very good at) or ergonomic in the slightest.
I'd like to see;
- Target info that doesn't draw outside your canopy support struts (FD draw order fail, give it a limit box and draw last/on top)
- Smaller more informative target icons in scanner
- Target brackets with pertinent combat info (I agree with Hitsuke, Hull/Shield, but I prefer %, current sub-target)
- Heading indicator (useful for FA-off folks)
- System coordinates (hell a decent system map that didn't resemble a DC comic would be nice)
- System heading, degrees above/below plane etc (the game knows exactly where you are, why can't the pilot?)
- Thinner above/below tie lines in scanner
- Configurable colours (hopefully soon)
- Lose the outer arcs (these qualify as clutter and do nothing)
- Target star/plot route on mouse (and straight on 'til morning, right explorers?)
... The list would go on for a while.
All this and more can be done without losing the feel or the 'look' of the UI as it is now.
And it could be done with switches and sliders in the Options menu so you can keep the 'FD standard UI' and information-hungry pilots can pop up more data if they want it.
Of course, good UI design is actually
rather expensive, which decreases the UI priority.
I love the look, but functionally, it's gimped. Apparently on purpose.
