Riusciranno finalmente i nostri eroi a venir fuori dal ginepraio in cui si sono cacciati ?

The Air Force is finished evaluating the proposed “interim” fix for the KC-46’s troubled remote vision system, and is moving toward finalizing the design of the “2.0” overhaul of the system.
The service and Boeing agreed in April, on the way ahead for the RVS—the system of cameras and sensors linking the operator inside the front of the tanker with the refueling boom system in the back - after design flaws had plagued KC-46 development and testing. 
The “2.0” proposal includes a hardware overhaul of the system, as well as the addition of new cameras, displays, laser rangers, and other components. 
In the short-term, however, Boeing proposed a “1.5” interim fix largely focused on software tweaks to improve the quality of the image the boom operator sees.

Boeing on Jan. 27 reported another $275 million charge to its KC-46 program, pushing the total cost overruns it is responsible for to more than $5 billion in the past six years - more than the initial contract award for the tanker.
The fourth quarter total means 2020 saw more than $1.3 billion in overruns for the program, a cost the company said in its earnings report was “primarily due to production inefficiencies, including impacts of COVID-19 disruption.” 
The 2020 total is more than any previous year, according to a review of the company’s prior year earnings reports.
Because of the nature of the contract, the company is responsible for all costs above the $4.9 billion award.

KC-46A ... un paio di problemi sono stati risolti ... per gli altri ci vorrà tempo ...

Quote

The Air Force recently resolved two Category 1 deficiencies on the troubled KC-46 tanker, both problems with the aircraft’s auxiliary power unit that could impact the safety of flight. However, the four remaining issues are still years away from being solved.
The KC-46’s APU, located in its tail, developed two serious problems, one with a duct clamp that was moving excessively and another with a drain mast on the outside of the tail that could potentially break loose. 
As of the end of January, both problems have been addressed, with one closed and the other downgraded to a Category 2, or less serious, deficiency, AMC boss Gen. Jacqueline D. Van Ovost told reporters Feb. 1.

The 157th Air Refueling Wing on Feb. 5 filled up its KC-46 hangars, receiving its 12th and final Pegasus as Boeing delivered the 44th tanker to the Air Force.
A crew from the wing at Pease Air National Guard Base, N.H., flew the tanker home from Boeing Field in Seattle. 
The base received its first KC-46 in August 2019, after divesting its last KC-135 in March the same year.

That’s one small step for man. One giant leap for Air Mobility Command ...”

Quote

U.S. Transportation Command is looking to integrate the KC-46 into operations as soon as June, following Air Mobility Command’s move to free up the troubled tanker for ops to relieve stress on legacy refuelers.
TRANSCOM boss Army Gen. Stephen R. Lyons recently visited KC-46 officials at McConnell Air Force Base, Kan., and said he is “encouraged by recent (Air Force) efforts that will make the KC-46 available for limited mission requirements as soon as June,” the command said in a Twitter statement.
The statement is an update from Air Mobility Command’s announcement Feb. 24 that it would clear the KC-46 to be tasked by TRANSCOM this year.

Si erano voltati dall'altra parte ... :scratch:

The Air Force didn’t effectively oversee the development of the KC-46’s refueling boom, leading to additional delays, costs and a lingering deficiency on the system that prevents the tanker from refueling some USAF aircraft, according to a new Pentagon watchdog report.
The Defense Department Inspector General, in a report released May 27, said the Air Force’s KC-46 Program Office didn’t effectively manage the development of the refueling boom, specifically following a redesign of the system in 2012. 
That year, Boeing presented a system design during the preliminary design review that “differed significantly” from the initial design from the 2011 contract award.
Despite the new design, the Air Force did not “ensure that critical technologies for the refueling boom were demonstrated in a relevant testing environment,” and it “did not verify full functionality” of the boom in accordance with the program’s own plan when they performed flight tests, the IG found.

Altro che telenovela ... 😱

Quote

A feature in the advanced refueling system of the KC-46, designed to improve safety and ease the burden on boom operators, is not working as designed due to a software flaw, so the Air Force implemented its own workaround as the service and Boeing wait for more pressing issues to be solved first.
The issue is with the aircraft’s Aerial Refueling Software, which has preset limits for individual receivers to control the boom’s independent disconnect system. 
Simply put, the system automatically selects the left/right and up/down limits for the boom to stay connected to an individual receiver, and if the movement exceeds the envelope of that aircraft, the boom automatically breaks away to avoid damage.
However, the presets in the system are not accurate for each receiver, so boom operators, before each connection, have to override the automatic preset limits and input correct ones. 
The problem was a Category II deficiency on the KC-46 before the workaround was implemented.
“The Air Force is aware of the KC-46 receiver preset issue,” Air Mobility Command said in a statement to Air Force Magazine.

L'Air Force è alla ricerca di un'aviocisterna che faccia da "ponte" fra il KC-46 e il successore "Advanced Air Refueling Tanker" (già “KC-Z”) ...

Quote

The Air Force is seeking options for a “bridge tanker” to fill the gap in tanker capacity anticipated between the end of KC-46 production and development of a future refueler.
USAF’s Life Cycle Management Center on June 16 issued a Sources Sought Announcement, seeking qualified, interested companies to provide a commercial derivative aircraft “based on existing and emerging” technologies. 
While specific requirements are not fully defined, the Air Force said the tanker can be crewed or uncrewed and does not need to be a low-observable aircraft.
The Air Force will release a final request for proposals by the end of 2022 once requirements are locked in.
“The KC-135 will be 70 years old when the Air Force expects to receive its last KC-46 delivery in 2029, and replacing these vital aircraft continues to be critical to the Air Force mission to project Rapid Global Mobility in today’s strategically competitive environment,” the Air Force said in a release.

Ora stanno dicendo che un paio di problemi, non rivelati in precedenza, sono in via di risoluzione ...

Quote

The Air Force and Boeing are addressing two previously unannounced Category I deficiencies on the KC-46. 
The issues, affecting the aircraft’s receptacle drain line tubes and Flight Management Instability, will be fixed at Boeing’s expense.
“There are no operational restrictions on fielded KC-46s due to either of these deficiencies, nor do they affect [Air Mobility Command’s] plan for KC-46 Interim Capability Release,” said USAF spokesman Capt. Joshua D. Benedetti in a statement. 
“The [System Program Office] and Boeing have established operational processes and maintenance procedures to mitigate impacts and ensure the issues do not add extra risk to personnel, aircraft or operations.”
The air refueling receptacle drain line developed cracks in low-temperature conditions, according to the Air Force, and Boeing is redesigning the drain tube to address the issue.
The aircraft have also suffered isolated incidents of Flight Management System instability during operations. 
Boeing and subcontractor GE Aviation identified the need for a long-term software fix, and for the short term, Boeing is developing updated procedures to ensure the system’s stability in flight. 
The issue came up recently in a March 3 flight over the Pacific, causing the crew to use other navigation systems to safely land in Hawaii ...

"2nd Air Refueling Squadron" ... addio, KC-10 ... benvenuto, KC-46 ... B-)

Quote

A KC-10 Extender took off into the dark and rainy New Jersey sky after a short weather delay to link up with F-22s flying over the Atlantic Ocean, marking the end of an era for its unit.
The June 30 flight for the massive tanker from the 2nd Air Refueling Squadron was a historic one for the Air Force’s second-oldest squadron. 
It was the last time a KC-10 assigned to the 2nd ARS would fly. 
The 305th Mobility Wing already has sent five of the tankers to the “boneyard” at Davis-Monthan Air Force Base, Ariz., as it prepares for the KC-46’s arrival in November.
The remaining Extenders from the 2nd ARS have shifted to the 32nd Air Refueling Squadron within the 305th Air Mobility Wing, which will become a “super” squadron until the last KC-10s at McGuire are retired in 2024. 
The base will bring on 24 KC-46s, and McGuire had 32 KC-10s before retirements began.

Avanti a piccoli passi ...

Air Mobility Command on July 9 officially opened up the KC-46 to some limited operations, clearing the Pegasus to use its centerline drogue.
The move is an official green light to conduct missions the Pegasus has been doing for months - using its secondary refueling system to pass fuel to aircraft such as Navy F/A-18s. 
The tanker is still years away from reaching initial operational capability as the Air Force and Boeing work to overhaul the aircraft’s problematic Remote Vision System and refueling boom.
