NW changed all or most of their 742Fs over to EFIS engine instruments and Kalitta Air has also including some ADI and HSI upgrades much like the Martinair 742. They are more reliable than the original and look good too.

Quoting Flynavy (Reply 8): Any idea if FX will retrofit their 757s FMS from PIP to Pegasus FMCs as well?
I certainly hope not. I have enough trouble getting the point across with the simple stuff we have now.
I personally perfer the Universal or the Smiths. The formats are very similar and there's very few boxes and no exotic interfaces. RC 9000 is okay too but the layout and keystroke routine isn't intuitive. The advantage would be that FX is already using the MCDU for radio control on the Airbus fleet so it wouldn't be new to the crews.
Just one opinion mind you. . .

Quoting Ex52tech (Reply 9): It is called EIDS, and they put it on all of the DC10-30s, DC10 -40s, and the 742 fleet also. It has the capability to take snap shots, and has an exceedence page. Very good system, works very well.
True, Penny & Giles designed that system, and Atlas Air also use it on their classics. The LCDs are quite small and not especially readable however. IS&S, who designed the 767/757 all glass update, have developed a better EIDS using a single much larger plasma display for Kalitta Air. The system includes a second display on the F/E panel which replaces the secondary engine instruments and a backup standby engine indicator.

It was KLM who lead the way with EFIS retrofits on 747-200s. They also added FMS, replacing the original INS, but retained the old engine displays. All these retrofits use LCDs or plasma displays. CRTs would have lead to an increase in the cooling requirements. The new systems log faults and exceedances so they are a big improvement for maintenance, over and above increased reliability.
The glass isn't half empty, or half full, it's twice as big as it needs to be.

Quoting Ex52tech (Reply 12): They weren't any smaller or harder to read than the original tapes. They also have a lock on any exceedence that pilots don't like to have documented.
I was thinking round dials v EIDS. The EIDS displays are about two inches shorter than the mechanical tapes, though more readable (good use of colour). The old tapes do record exceedances, but not as comprehensively (or tamper free) as the EIDS. However compared to round dial presentation the EIDS is not as readable and I know crews who thought the conversion of round dials to EIDS was a backward step (then again some crews liked it). Only about half of the EIDS panel area is devoted to displaying information. The IS&S EIDS system I mentioned earlier has a separate control panel and a large display, all of which is devoted to displaying data.

"Tamper free" would be the key words here.
I came from an airline which used the round dials, to an airline that used the tapes. I absolutely hated the tapes, we had to have one guy in the cockpit trying to read and write down the tape readings while we were conducting high power engine runs. The nice feature about the EIDS was taking a "snap shot" while at power, and then recalling those readings when returning to idle.
Personally going from round dials to the EIDS would have even been a step backwards.
