777 Troubles; Latest News

The good news- I failed at searching out prior 777 Troubles threads.

The bad news:

Delta to retire it's 777s

Could this be the first phase of

Delta to retire (itself)

??

On a related note, do we believe the Airbus in question really burns 21% less fuel per seat than the 777? That seems like an awfully large number when comparing two relatively modern aircraft.

[21%] seems like an awfully large number when comparing two relatively modern aircraft.

Concur.

Maybe It’s really that the new “Evan style” pilot can’t deal with yokes and phugoid type behavior? The aircraft is apparently hard to hand land on beautiful clear days, too.

For whatever reason, the 777 program never became much of a thing at DL. They only have 18 of them (compared to 67 at AA and 96 at UA), they were constantly moving them around routes, and just in general didn't seem to believe in the airplane all that much, so I'm not surprised they're getting rid of them. Whether the 350 is in fact 21% more efficient I know not, but it does have 10 more seats and carries more cargo, so...

As part of our fourth-quarter results, we also shared that we now anticipate that the first 777X delivery will occur in late 2023. This schedule, and the associated financial impact, reflects a number of factors, including an updated assessment of global certification requirements, our latest assessment of COVID-19 impacts on market demand, and discussions with customers with respect to aircraft delivery timing. We remain confident in the 777X and the unmatched capabilities and value it will offer our customers.

Here is a headline i made up to "add interest" to the article.
Boeing, Fearing the Worst, Sends 777X To Alaska

Boeing 777X Aircraft Ferried To Alaska For Cold Soak Testing
February 7 - Excerpt

A Boeing 777X test aircraft has been ferried to Fairbanks, Alaska, to undergo cold soak testing. This week’s move is part of the type’s preparation program ahead of its introduction in 2023.

According to Airline Ratings, the unit currently holds registration number N779XZ. It was ferried from Seattle to the Alaskan city to perform a series of tests. These experiments include the monitoring of how significant cold conditions can impact different parts of the plane. Therefore, Alaska is the perfect location at this time of year.

There are several factors to consider with this aspect of testing. For example, metals contract at different durations. Moreover, lubricants may expend their viscosity, which can create wear problems for moving parts. Plastic and rubber materials could also become brittle. The trial involves shutting down the plane for 24 hours before actioning a cold start.

What?!?!?

[elaw]

Scientists using super-sensitive microphones have recently discovered that, like humans, in very low temperatures most metals will start saying "Damn it's cold" at regular intervals. However the time for that to start happening differs according to the particular alloy, thus the "durations" comment.

Siberia is superior cold soak

Boeing 777-9 performing runway tests in Oklahoma
(This is the first 777X to fly, back in January, 2020.)

Boeing has sent one of its four 777-9 test jets to Clinton-Sherman airport in Oklahoma for a series of tests that will primarily examine the jet’s performance on the runway.

Test aircraft designated “WH001” (registration N779XW) arrived at the airport in the western part of Oklahoma in recent days.

“We’re in Oklahoma for testing with our new Boeing 777-9,” Boeing says. “We’re conducting a comprehensive series of tests and conditions, on the ground and in the air, to demonstrate the safety and reliability of the design.”

he company confirms to FlightGlobal that the jet will primarily complete runway-related tests at Clinton-Sherman. The airport’s main runway is 2.6 miles (4.1km) long.

The aircraft will be at Clinton-Sherman until sometime in March, Boeing adds.

Boeing’s flight-test programme for the GE Aviation GE9X-powered 777-9 began on 25 January 2020 when aircraft WH001 took off from Paine Field in Everett, Washington. At that time, Boeing had intended to begin 777-9 deliveries in 2021.

We flew over Clinton-Sherman the other day on our way to ATL from LAS.

Boeing Subjects 777X to Severe Crosswind Tests


AMARILLO, Texas (KVII) — Boeing is taking advantage of the powerful cross wind in the Texas panhandle to test its new commercial jet.
Test pilots landed the new 777X at Rick Husband Amarillo International Airport on Monday afternoon.
They'll be testing through Wednesday, when winds will be sustained at 30-45 mph in the afternoon with gusts over 60 mph.
Boeing crews said they came to AMA for the high winds and long runway.

The Boeing 777X is the latest long-range, wide-body, twin-engine jetliners in the Boeing 777 family.
At 251-feet, 9-inches, the Boeing 777X will the longest commercial aircraft ever built. It will be able to carry up to 426 passengers.

Boeing 777X certification continues to progress: EASA

Comment: The headline editor needs to try harder. It might have said, Champaign Corks Pop at Boeing Headquarters as European Safety Agency Signals Potential Acceptance.

Excerpt:

The European Union Aviation Safety Agency’s (EASA) Executive Director Patrick Ky has indicated that the certification progress of the Boeing 777X continues to progress, despite initial disagreements between the manufacturer and the authority.

In an interview with Aviation Week, Ky suggested that while the agency found several issues where it and Boeing disagreed, solutions had since been found, allowing certification of the 777X to progress. The main disagreement, according to sources familiar with the matter and cited by Aviation Week, was that the manufacturer and EASA conflicted over the aircraft’s flight control system’s exposure to potential failures following but not limited to lighting strikes, maintenance lapses or software errors.
