Delta has quite a few old, but nicely refurbished 757s flying their transatlantic routes (especially from NYC to Lisbon, Edinburgh, etc.).

These planes are on average 21 years old, some much older.

Delta completely refreshed the interiors a few years back (screens, seats, lighting, WiFi, etc.).

But I am curios to know how much of the plane's technical parts and internal systems were refreshed/replaced? For example, the PW2000 engines, CRT screens, GPS, navigation, and other avionics, etc.? Are they all original and old from the early 1990s, or have they been replaced and brought to the modern safety and other standards?

Aircraft systems are continually upgraded to meet reliability goals and upgraded safety standards and regulations. I can't speak to what Delta has done, but I'm sure there has been continual improvement.

We are currently upgrading our B757 aircraft to a Large Display System, replacing the 6 CRT's with 3 large LCD's. But, even before this mod, the avionics barely resembled the avionics of the aircraft as delivered.

As for engines, they are monitored, removed, overhauled and installed...over and over again.

Delta's 75S config flying TATL routes entered service for TWA 1996-1999. Delta has older 757s but these aren't among them.

Three large LCD’s ?


That’s an interesting retrofit on the 757, do you have a picture?

That’s a nice setup, definitely looks 787ish

Just to add some additional information on the 757. When I was at NW, I flew the 757 for about a year in the right seat. At that time, there was no GPS, the FMS was updated using DME/DME hierarchy only. The MTOG was 180,000, can't remember the MLW. The ACARS was new to NW and there was no interface with the FMS and the options were fairly limited.

Look at the 757 now. Like night and day when compared to what they were like in their original delivery condition and what they are equipped with now.

At FX they have the Rockwell Collins set up like shown and they had them put in right after they came off the assembly line on the 767. But the 757 they put the ISS cockpit or MAUI

180K MTOGW? Are you sure that was not the MLW? Most recent numbers for the 757-200 are 255 MTOGW amd 210 MLW with a 184 MZFW. Even most 727-200 were up around 191 MTOW and went slightly above 200K for pax models

I am very sure of it. IIRC, NW's original build 727-200As were 176.5 with a MLW of 155.0. The 757 had a config of 184 Pax. So it was pretty lightly loaded. I want to say there were 24F and 160Y. But again, my last flight on the 757 as crew was in 1986.

It sounds light MMO,


If you limit the max take off weight to 180K
on a 757 you couldn’t carry a full fuel load
with an empty aircraft


Our 757’s have an OEW around 130k and a fuel capacity of 75k, they are later series aircraft but you can see that puts you at 205k with no payload



Our initial 200 series MGTOW was 240, later raised to 255k for all aircraft

Interesting, seems to indicate to me that those 757s are gonna be around for awhile. Any 763s expected to get this treatment?

All of them. I'm not sure how the new ones are going to be dealt with.

I suspect that the new Collins flat plate does away with the Symbol Gnerators that are part of the old school Honeywell design. 3 SB each in the old design and at 130K per unit a very expaensive replacement when they go bad, which is not that uncommon.

The Rockwell Collins setup has GGU graphic generators instead of SG's they have 3 of those also.

The ISS set up looks nice, very neat installation, didn’t Delta do this?

I read somewhere however that it hasn’t lived up to expectations

The ISS is way inferior to the Collins system. Didn't help that DL had a major lawsuit going against the ISS folks over some previous issues on the MD88 series.
