Aloha 737-200 From , joined Dec 1969, posts, RR: Posted (12 years 9 months 6 days 8 hours ago) and read 1876 times:
Before the attacks on September 11, Boeing was considering modifications to its 757-200 line. As the Boeing 757 design nears 20 years of age, a replacment or upgrade needs to be considered, as the 739 comes close, but doesn't exactly match up the the Boeing 757 in terms of performance, load, range, etc.
I think that a low-cost upgarade to the 757 should be in order, and might make for a longer production of this great aircraft. My ideas are as follows.
As you all know, the 777, 767-400 and 737NG all have a very similar flight deck, so would it not be a good idea to introduce an NG flight deck to the 757? It would provide better commonality for the future, and Boeing could add a feature like they have done with their 737 NG aircraft that allows the CRTs to dispaly the old instruments on new screens. This would allow the 757-200ERX/NG to be compatible with earlier 757 versions, but with an updated flight deck, compatible with most Next Generation Boeings.
Boeing could also make aerodynamic modifications, such as raked wingtips, or winglets, to improve range, also perhaps slightly modified Rolls Royce engines. I hear RR was considering an upgrade to their RB-211 using some parts from Trent engines, could this be a good improvement for the 757?
Now dont get me wrong I'm not saying that the 757 is obsolete, but the 757's current flightdeck and engines don't provide the latest technology the airlines want. However, I do not think an FBW upgrade would be a good idea.
In essence, if Boeing redid the 757 a bit, added new cockpit, aerodynamic upgrades (winglets/wingtips), added fuel, and perhaps upgraded the engines, it would make for a very interesting new 757, and the cost would not be all that high. Boeing already uses the technology I'm talking about on their NG aircraft, so it wouldn't be as expensive as something right off the drawing board.
Also, I wonder if the 757 cabion could be upgraded. That is the least of the worries, but it is a though, perhaps a scaled down 777 style?
Also, didn't CO have firm interest in the 757-200ERX before the attacks? Where does the program stand now?
I do not see any information on the Boeing website about the 752ERX, I'm afraid they may have scrapped the project, and I certainly hope they didn't. I love the 757-200 and would hope that Boeing upgrades her and keeps her in production for the next 20 years.

There'll eventually be 767X and 757X aircraft, but not at the moment. A 767X is more likely than the 757X, or at least will appear before the 757X. Engine, aerodynammics, interior, cockpit are the 4 big areas. I agree, a 737NG/777 style flightdeck would be GREAT. The 767-400ER cockpit and interior mustn't be that hard to impliment on the rest of the 767 fleet, but the aerodynamic mods and engines are going to be a problem.

I know Delta it putting 777 style interiors in some of their 757s. I flew on one CVG-DEN and it was VERY nice! 777 style seats with leather headrests, curved seats, and new style overhead bins.I never wanted to get off it and I wish it had been longer than 2 hr flight time. And in your comment to the 757 being replaced I am thinking the new 787/27-07 will be a likley replacement or addon

It's ok Boeing saying they're going to re-engine the 752/753 and 762/763, but the engine manufacturers are businesses too. They're only going to develop a new engine if Boeing can gaurantee they can sell, say, 300 units with that particular engine. CFM agreed to modify the CFM56-3 to create the CFM56-7 because Boeing could gaurantee over 1000 sales of the 737NG. Boeing probably couldn't do the same thing with a 757X/767X.

The engines still seem very good to me. Doesn't the 757 produce the lowest seat/mile cost of any jetliner currently flying?
I still think a modified flight deck and larger fuel tanks (as in the -ER variants of the 767) could help it sell a few more.
The biggest problem the 757 faces is it's size. Some airlines regard it as too large for domestic routes, and in the case of BA, the type is being replaced by the A319 and A320.
However, the 757 has already seen success on low density long haul routes, and given the current economic climate, the type is ideally suited to regular hops accross the North Atlantic. Just look at how well CO did with their 757 fleet. So if it is becoming too big for certain short haul routes, then Boeing must push the ERX as a cheaper alternative to the likes of the A330-200, and maybe even market it as a replacement for elderly 767-200's. Just an idea....

I seriously doubt the 757ERX program has been scrapped. 9/11 and even maybe the Sonic Cruiser is the reason for the program not seeing much light recently. I say Sonic Cruiser because it is planned for it to have a family of 100, 200 and 300 tri class seating. Also, the 757ERX is most likely designed for trans-atlantic flights. This would be the Sonic Cruisers' forte'. (sp?) However, it would be benificial to Boeing to still study this aircraft for lower cost carriers. I agree Aloha 737-200, a cockpit upgrage for the 757 is overdue.
