And typically my 1:400 scale model (sans winglets) arrives this week…:rolleyes:

757

There is one picture that just characterizes the B757;

That’s some Yaw! On take off I presume.

J, Boyle….The A320 Winglets by APB….was this Aviation Weekly an old one? I knew that Airbus were trying out the APB designed winglet, does the magazine suggest it was a failure due to the flex?

I got it wrong.
Between the time I read the magazine and posted what I wrote, I somehow got the facts a bit off.
I can’t blame drinking because I don’t drink and I’m too young to claim a “old age” moment. 😀
Sorry for the incorrect statement.

What the magazine actually said was:
“Airbus hopes the winglets will provide a smaller percentage fuel burn improvement, without requiring substancial wing stiffening. Earlier designs were rejected, Airbus officails have said, because the required wing-stiffening
largely offsetthe efficiency improvement.”

So my point was that with similar AP winglets, the 320 would have required wing stiffening which would offest any gain provided by the winglets.
Because of the wing flex, the new winglets being tried will provide a smaller improvement in efficiency than winglets on a 737.

The firm that makes the winglets is Aviation Partners!!

Aviation Partners Boeing (APB) actually. Their front office is Aviation Partners Inc. The initial team were ex Boeing.

Re: Winglets…the 737 has them.
I saw something in Aviation Week about the firm that makes them (not Boeing) saying that they are not retrofitable to the A320 series because of “wing flex”.

I’m no engineer, but that would seem to indicate that the 320 family can’t take advanage of the fuel savings offered by winglets…
Discussion?

Unfortunately, Fedex was loathe to order new airplanes. Had they done so, perhaps production would have continued.

UPS did take new 757’s but I don’t believe Fedex has ever taken new airplanes, and in fact have never ordered new until their A380/777 orders (still undelivered, A380’s cxld and 777’s dlad.)

Well, life as a freighter was always a certainty in my mind.

If orders aren’t forthcoming what choice did they have..you’ve gotta have the sales figures to keep them in production.. as was mentioned in the 764 post

The irony is, not long after they ceased production, the 757 experienced a renewed growth of popularity as Airlines began long thin routes from the US to Europe. The 757 has aced this role.
I reckon Boeing could have had another 30 or 40 orders in the bag if the line had remained open.

But, there are times you just have to say “no more”.

The 757 never ever gained any orders from the Oceania region for some unknown reason…i think the Kiwi Air Force purchased a couple which were second hand ..but that’s about the only one’s i know of

Taking the 757 out of production was a weird decision…..guess they could never make them at at a profitable rate of production

There is no true replacement for the 757. It occupies a unique place in the lineup of airliners. I think at one time Boeing advertised it as, “The largest single aisle airplane that can profitably be built and operated” or some such. And that was before the -300 was built.

I’ve studied this airplane for quite awhile, and near as I can tell, the biggest problem was that it had widebody systems (three hydraulic systems, three autopilots, etc.) but was unable to generate widebody revenue. Although we never really know what airlines really pay for airplanes, the thinking seems to be that Boeing wouldn’t sell the airplane at a price consonant with the revenue it is able to generate.

Nevertheless, I’ve always felt that it never got it’s due. It is a very, very efficient airplane. The fuel burn per seat is almost 20% less than the 767-300ER on a similar routing (a short North Atlantic run), and this is amazing since a larger airplane often has an advantage in this statistic due to the larger number of seats. Its true that the PW2000 has been extremely unreliable (something else that is largely unreported), but it is lighter than the competing RR engine. The RR product runs about 3 times longer on the wing though.

Even the 787 is not a true like-for-like replacement for the B757, it is quite a bit larger, and more importantly far heavier!

Not like for like, but isn’t it supposed to be an ‘ideal’ replacement for those airlines operating both the 757 and 767 ? Another reason to keep the 757 in manufacture a few more years, could of course be the types sudden resurgence in popularity on the atlantic routes, given the success of the blended winglets. Just my opinion of course, I’ve followed the success of the 757 since it first arrived in this country some 25 years ago and then some.

Is the 737-900 considered to be the replacement for the 752 ?

I can’t help but wonder if it would still be in production were they to know of the 787 problems and delays ?

All of our (US Airways) ETOPS 757 have had winglets installed. They are more efficient, apparently, but they seem nose heavy on take off. I’m not sure if they calculated a new Take Off trim setting index based on the modification. They look great.

The 753’s aren’t ETOPS certified so they’ll need to take care of that too. All these years they’ve been flying them and they are stuck flying domestic.

I should think MAN will get one too.
even before the withdrawal of BA, they were looking to increase capacity but all the widebodies were fully utilised and needed on the routes they were placed.
While only a small increase in cpacity, may just be what CO needs

Also think EDI and LHR will get them (in winter when LHR sees B757 ops)

Just my 2 cents
