I currently fly C-130As and EC-130s (all analog "steam" guages) but I am currently on leave doing some flight test for a C-130 that is modified with six MFD's. Two Pilot displays, two nav displays, engine display and system display (yes, the nav position was removed and now it is a nice table to have lunch at). I would have to say after getting used to the way information is displayed and how it is displayed, it is a pretty good system. I have not stopped scanning like I do when I fly my beloved "steam guages". But it is nice when there is a malfunction or if you are exceeding a limit, the guage will alert you. I have found myself getting a bit "quick" to respond when we have a guage go red so I can see that being a learning curve as you will need to actually analyze the situation before you react, you tend to want to correct the red guage post haste. The only thing that i see a flaw in was when we lost all of the engine display and system display panels inflight, now there is a reversionary system and when we selected it, it didn't work either. We found ourselves flying back to base and truly didn't have any engine or system indication (found out it was the test engineers computer harness hooked into the computer). But the seat of your pants works well...lol. Overall, my opinion is it is a good system and it will serve us well. But of course, it is human nature to be resistant to change, we like the comfy chair we sit in...
Qualifier, the system I am talking about is not the Boeing AMP mod the USAF has elected to upgrade aircraft with. I am not speaking on behalf of Boeing or the AMP program, but more from an operator's perspective on upgrading the C-130 fleet (what do I care, EC-130s aren't getting AMP anyway, lol...)
PS. EPCS kicks butt...truly love it.
