Fuel Efficiency of the GEnx-Powered Boeing 787-10 Compared to Other Widebody Aircraft A recent study conducted by *Aircraft Commerce* has identified the Boeing 787-10, equipped with GE Aerospace’s GEnx engines, as the most fuel-efficient widebody aircraft currently in operation. The analysis reveals that this particular engine-airframe combination achieves the lowest fuel burn per available seat mile (ASM) among all widebody models assessed. This performance surpasses not only the 787-10 variant powered by Rolls-Royce’s Trent 1000 engines but also the Airbus A350 family and older widebody aircraft such as the Boeing 777-200ER, 777-300ER, and 747-400. Comparative Analysis Across Multiple Routes Published in the December 2018/January 2019 issue of *Aircraft Commerce*, the study evaluated 14 widebody aircraft-engine pairings over five routes of varying distances, utilizing fuel consumption data provided by Lufthansa Systems. The aircraft included in the comparison were the Boeing 787-8, 787-9, and 787-10 models, each with both GEnx and Trent 1000 engines, alongside the Airbus A350-900, A350-1000, A330-200, A330-300, and several Boeing 777 and 747 variants. The GEnx-powered 787-10 consistently demonstrated the lowest combined fuel burn and en-route air traffic control charges per ASM across all routes tested. The margin of superiority was notable, with the GEnx-equipped 787-10 leading the rankings, followed closely by its Trent 1000-powered counterpart. The Airbus A350-900 remained competitive but did not match the fuel efficiency of either 787-10 configuration. Older aircraft models, including the 777-200ER and A330 series, showed significantly higher fuel consumption rates, underscoring the advancements embodied in the newer generation of aircraft. Engine-Airframe Synergy and Operational Implications The study highlights the critical importance of selecting specific engine-airframe combinations when evaluating aircraft operating economics. While the Boeing 787-10 offers similar passenger comfort and maintenance profiles regardless of engine choice, the fuel cost per ASM varies substantially over the aircraft’s operational lifespan. The independent, route-based data provided by *Aircraft Commerce* offers airlines a valuable resource that extends beyond manufacturer marketing claims, enabling more informed fleet decisions. The GEnx-1B engine’s superior efficiency is attributed to its advanced design tailored specifically for the 787 program. As a two-spool high-bypass turbofan derived from the GE90 engine used on the 777, the GEnx-1B incorporates lighter materials and an improved thermodynamic cycle. Its 18 composite fan blades, each measuring 111.1 inches in diameter, represent the first commercial application of carbon fiber composite fan blades at this scale, contributing significantly to weight reduction and fuel savings. Market Impact and Competitive Landscape Despite the current lead held by the 787-10 with GEnx engines, competition remains intense. The Airbus A350, the 787-10’s closest competitor, also employs advanced materials and aerodynamic innovations to enhance fuel efficiency. In response to the 787-10’s market success, Airbus continues to refine the A350’s technology to sustain its competitive position.

While AI is widely regarded as a catalyst for innovation, it also raises significant concerns about job security among workers. Recent Gallup polling reveals that nearly half of adults aged 18 to 29 (47%) now perceive AI as more harmful than beneficial, marking the largest increase in skepticism among any demographic group. At the Farnborough Air Show in England, Wendy Poischbeg, CEO of The Greater Everett Chamber of Commerce, highlighted the continued importance of human involvement despite the growing integration of AI technologies. She emphasized that in aerospace, where safety is paramount, “The human element is number one. You cannot mess up once. AI has to be perfect every single time, especially when it comes to aerospace and putting people in the sky.” This perspective underscores the industry’s cautious approach to adopting AI, prioritizing human oversight to ensure reliability and safety. Technological Adoption and Workforce Adaptation Everett’s aviation sector, led by major employers such as Boeing, is actively incorporating AI-driven innovations to enhance operational efficiency and safety. Boeing has introduced several AI applications, including a slide-in cart for 767 mechanics, photo-based AI tools for part inspections, and projected instructions for assembling the 777X wing. These advancements aim to improve production quality and streamline processes. However, they also necessitate that workers acquire new skills and adapt to evolving roles, fueling concerns about potential job displacement and the imperative for continuous workforce training. For recent graduates and students, the impact of AI on career prospects is a pressing consideration. Many are carefully evaluating their professional paths in light of AI’s growing influence, while educational institutions are increasingly integrating AI-related skills into their curricula to prepare students for the changing job market. Poischbeg noted that workforce issues were a central topic of discussion with nearly every company she engaged at Farnborough, reflecting Snohomish County’s strong reputation for skilled labor and effective training programs. “Washington State continues to be attractive because of our talent,” Poischbeg remarked. “I love being able to talk about our training programs and what is working.” She stressed that sustaining Everett’s position as a key aerospace production and supply chain hub depends on both technological innovation and a well-qualified workforce. Outlook for Employment in the AI Era Despite the transformative effects of AI, industry forecasts remain optimistic about employment growth in aviation.

Seven-Year Delay Renders 30 Completed Boeing 777-9s Financially Obsolete Certification Delays and Regulatory Challenges The 2026 Farnborough Airshow, while highlighting advancements in aviation technology and securing significant aircraft orders, also brought renewed attention to Boeing’s beleaguered 777X program. Emirates President Sir Tim Clark, a prominent customer, publicly rejected the first ten early-production Boeing 777-9s stored at Everett, likening them to “baked bean cans.” His pointed remark underscored a troubling reality: over 30 completed 777-9 aircraft, some already painted in customer liveries, have become financially obsolete without having flown a single commercial mile. This predicament stems from a seven-year delay in certification that has fundamentally disrupted Boeing’s manufacturing and delivery plans. When the 777X program was launched in 2013, Boeing anticipated a relatively smooth regulatory process, expecting early production models to roll off the line by 2019 with only minor retrofits required before delivery. However, following the 737 MAX crisis, the Federal Aviation Administration (FAA) significantly overhauled its compliance standards. The agency abandoned its previous practice of delegated certification, subjecting every aspect of the 777-9 to rigorous scrutiny. This led to repeated shifts in the certified baseline design, forcing Boeing to continuously revise manufacturing drawings and leaving early 2019 and 2020 airframes increasingly misaligned with evolving regulatory requirements. Manufacturing and Financial Implications Boeing’s initial “build-and-store” strategy, designed to protect global supply chains, quickly became a logistical and financial burden. More than 30 early-build 777-9s have accumulated in storage at Paine Field, exposed to the damp climate of the Pacific Northwest. As these aircraft remained idle, their systems became technologically outdated, and the cost of upgrading them to meet the latest standards escalated dramatically. Far from generating revenue, these stored widebodies have instead consumed capital, contributing to an estimated $15 billion in accounting charges and program write-downs. The process of “change incorporation”—retrofitting stored aircraft to comply with new certification standards—has proven far more complex and costly than initially anticipated. Unlike standard assembly, retrofitting requires engineers to dismantle completed cabins, cut into sealed structures, and remove intricate wiring to access components needing replacement. This labor-intensive procedure disrupts production economics and renders restoring early-build aircraft to airworthiness a formidable challenge. Industry Impact and Future Outlook Frustration among airlines over the 777X delays continues to mount, compounded by concerns regarding engine costs, maintenance delays, and overhaul bottlenecks. Emirates, the largest customer for the 777X, now anticipates receiving its first 777-9 deliveries in the second quarter of 2027—several years behind the original schedule. There is a growing risk that by the time these aircraft enter service, they may already be surpassed by newer technologies. The FAA currently expects to certify the 777-9 late this year or early next year, but the damage to Boeing’s program is already extensive. More than 30 completed aircraft remain in limbo, requiring extensive and costly modifications before they can be deployed commercially. The 777X saga serves as a cautionary example of how regulatory upheaval, production miscalculations, and rapid technological change can combine to render even the most advanced airliners obsolete before their inaugural flight.

The Think Tank members concur that when these elements align, data becomes a strategic asset that supports faster decision-making, improves situational awareness, and delivers superior outcomes for both passengers and operators. This topic will be further explored during the FTE Data Sharing Think Tank session at the 20th anniversary FTE Global event, scheduled to take place in Dallas, Texas, from September 8 to 10, 2026.

Pilots’ Union Raises Alarm Over Engine Shutdown Risk in Airbus Aircraft The British Airline Pilots’ Association (BALPA), representing flight crews from major carriers including British Airways, Virgin Atlantic, and EasyJet, has issued a serious warning regarding a latent mechanical defect affecting several Airbus aircraft models. The union’s concerns focus on a fault within the engine fire shutoff buttons, which could inadvertently trigger sudden engine shutdowns during flight, posing significant safety risks. Incident Background and Regulatory Response The issue first emerged following a December 2024 incident involving an Air New Zealand Airbus A320neo. Approximately 15 minutes after takeoff, the aircraft’s right-hand engine unexpectedly shut down while carrying 142 passengers and six crew members. The pilots declared a Mayday after discovering that one of the engine fire shutoff buttons—designed to isolate power to the engine in emergencies—had activated without any manual input. Subsequent investigations revealed that a retaining pin inside the button mechanism had been bent during installation, likely due to mishandling. Routine vibrations during flight caused the pin to dislodge, inadvertently triggering the button. In response, the European Union Aviation Safety Agency (EASA) issued Airworthiness Directive 2026-0134, mandating inspections of the engine fire shutoff buttons on affected Airbus models, including the A319, A320, and A321. Airlines are required to replace the module if a bent pin is detected, with a compliance deadline set for November 2027. BALPA, however, has expressed unease over this timeline, describing it as “understandably uncomfortable” given the severity of the defect. Broader Implications and Ongoing Concerns Despite regulatory measures, the problem appears to extend beyond the aircraft models currently covered by EASA’s directive. In February, a similar event occurred on a British Airways Airbus A350-1000 en route from Las Vegas to London Heathrow. While cruising over Halifax, Canada, the right-hand engine lost power unexpectedly. The cockpit’s Electronic Centralised Aircraft Monitor (ECAM) provided only brief alerts, failing to immediately indicate an engine failure. The crew was able to restart the engine only after resetting the fire switch, following guidance from maintenance control, allowing the flight to continue safely. BALPA has highlighted that the same type of engine fire panel is installed on both narrowbody and widebody Airbus aircraft, including the A350, which is not currently subject to EASA’s inspection directive. The union emphasized the latent nature of the defect, noting that “there is no ECAM cue until the moment it happens,” and that safe outcomes have so far depended heavily on effective crew response. This warning arrives amid broader industry concerns regarding engine reliability. The revelations may prompt increased scrutiny of Airbus aircraft and could potentially affect customer confidence. Competitors such as Boeing, which is contending with its own delivery delays and engine reliability challenges, may seek to leverage Airbus’s difficulties by underscoring their own safety records. Regulatory actions like EASA’s directive are expected to influence airline operations and market dynamics in the near future. Safety Considerations and Industry Impact The engine fire shutoff button on Airbus aircraft is intended solely for use in confirmed engine fire emergencies and does not automatically deploy fire suppressant systems. The recent incidents underscore the critical importance of rigorous inspection and maintenance protocols to safeguard passenger safety. As investigations continue, the aviation industry faces mounting pressure to address these mechanical vulnerabilities promptly to prevent future occurrences.

The Fate of Widebody Aircraft After Their Final Commercial Flight When a widebody aircraft completes its final commercial journey, its operational life does not simply conclude. Although it ceases to generate revenue through passenger or cargo transport, the aircraft remains a valuable asset. Comprising certified components, recyclable materials, and sophisticated engineering, these aircraft can continue to yield economic returns long after retirement. Thus, the end of commercial service marks the beginning of a new phase, driven predominantly by financial considerations. Economic Drivers of Retirement and Storage The ultimate disposition of retired widebody aircraft—such as the Boeing 747 or Airbus A340—is influenced by a range of factors including the aircraft’s age, maintenance record, demand for spare parts, opportunities for cargo conversion, and the residual value of its materials. Owners and leasing companies carefully evaluate these elements, often prioritizing financial outcomes over sentimental value. For many aircraft, the final passenger flight is merely the initial step in a carefully orchestrated retirement strategy. Following retirement, most widebodies are relocated to specialized storage facilities, commonly referred to as aircraft boneyards. These sites, frequently situated in arid regions like the US Southwest—including the Mojave Air and Spaceport in California, Southern California Logistics Airport in Victorville, and various locations across Arizona and New Mexico—offer optimal conditions for aircraft preservation. The low humidity and stable climate significantly reduce corrosion, enabling planes to be stored outdoors for extended periods. Internationally, Alice Springs in Australia has emerged as a notable storage hub, accommodating aircraft from carriers such as Singapore Airlines. During the COVID-19 pandemic, these boneyards assumed a critical role by housing hundreds of grounded aircraft worldwide. Typically, the final commercial flight is succeeded by a ferry flight operated solely by pilots, after which the aircraft undergoes thorough inspection, documentation, and parking. Despite their seemingly dormant state, storage operations are highly systematic, with technicians actively working to maintain and preserve the aircraft’s value. Preserving Value and Exploring Future Options Widebody aircraft may remain in storage for months or even years, incurring considerable costs during this period. Some are parked immediately after retirement due to strong demand for spare parts, while others await favorable market conditions. Throughout this phase, every decision is guided by the objective of maximizing financial return, as these aircraft can retain multimillion-dollar value even after commercial service ends. Not all stored aircraft are destined for dismantling. Some may be converted for cargo operations or potentially returned to service if market dynamics improve. However, such transitions involve significant challenges, including regulatory compliance, substantial upfront investment, and rigorous testing to ensure safety and operational efficiency. Industry Trends and Future Outlook Despite these complexities, market sentiment remains optimistic, particularly for modern, fuel-efficient widebodies like the Boeing 787. In response, manufacturers are investing heavily in the development of high-speed and ultra-efficient aircraft, intensifying competition within the industry. As global air travel continues to expand—especially in emerging markets—the demand for new, efficient aircraft is expected to grow. This ongoing evolution ensures that widebody aircraft, even after their final commercial flight, continue to hold a significant place in the dynamic global aviation landscape.

Flight SK983, operated by an Airbus A350-900 registered SE-RSF, departed Copenhagen at 13:04 local time, embarking on a scheduled 12-hour and 35-minute journey to Tokyo Haneda Airport. Approximately one hour into the flight, at cruising altitude of 37,000 feet, the flight crew detected a loss of oil pressure in one of the aircraft’s Rolls-Royce Trent XWB engines while over Polish airspace. In accordance with established safety protocols, the crew promptly shut down the affected engine and initiated a return to Denmark. The Airbus A350, a modern twin-engine aircraft, is certified to operate safely on a single engine for extended periods. The crew executed a routine approach, and the aircraft landed safely on Copenhagen’s runway 22L at 15:14 local time, just over two hours after departure. Emergency services were on standby as a precaution, but the landing proceeded without incident, and all passengers and crew disembarked safely. SAS confirmed the diversion, describing the return as a precautionary measure. The airline immediately began efforts to re-accommodate passengers and planned to dispatch a replacement aircraft to Tokyo, targeting a departure at 16:00 local time. Implications and Industry Response The incident is expected to attract scrutiny from aviation safety authorities, who may initiate investigations into the cause of the engine malfunction. Depending on the findings, this could lead to further inspections or temporary groundings of similar aircraft models. The reliability of the Rolls-Royce Trent XWB engine may also come under review within the industry, potentially influencing future fleet decisions by airlines. Market reactions could include a short-term decline in SAS’s stock price due to negative publicity and investor concerns. Competitor airlines might leverage the situation to highlight their own safety records, aiming to reassure passengers and gain a competitive advantage. The event is likely to prompt broader discussions about aircraft engine reliability and operational safety standards across the aviation sector. Despite the disruption, SAS emphasized that passenger safety remains its highest priority and affirmed that all procedures were followed in accordance with international aviation standards.

F-47 Set to Fly Three Years Before Engine Completion, Raising Concerns Unprecedented Development Timeline The engine of a fighter jet is fundamental to its overall performance and operational capabilities. Historically, aircraft manufacturers have integrated engines into their demonstrators prior to flight testing, a practice exemplified during the development of the F-22 Raptor. In that program, both Northrop Grumman’s YF-23 and Lockheed Martin’s YF-22 prototypes were each powered by two different next-generation engines—the Pratt & Whitney YF119 and the General Electric YF120—ensuring thorough evaluation before advancing. This dual-engine strategy is mirrored in the current US Air Force Next Generation Air Dominance (NGAD) program, albeit with a notable deviation. In March 2025, the US Air Force selected Boeing’s F-47 as the manned platform for its sixth-generation NGAD initiative. However, as of mid-2026, a final engine choice for the aircraft remains pending. Despite this, the F-47 is slated for its maiden flight in 2028, a full three years ahead of the anticipated completion of its intended next-generation Adaptive Cycle Engine. This accelerated timeline has elicited concern among defense analysts and industry experts regarding the aircraft’s reliability and operational readiness. Program Commitments and Industry Challenges The Air Force maintains its commitment to the 2028 flight target, emphasizing the advanced progress of the program and the close collaboration with industry partners. Officials contend that the F-47’s development benefits from lessons learned in previous fighter programs and ongoing technological advancements. Nevertheless, this approach marks a departure from the more cautious schedules traditionally observed in earlier X-plane and next-generation engine programs, which frequently encountered delays and protracted development periods. The F-22 Raptor, once regarded as the preeminent air superiority fighter upon its 2005 introduction, has seen its technological advantage erode in the face of evolving threats. The emergence of sophisticated integrated air defense systems and advanced adversary aircraft, such as China’s J-20, has heightened risks to US air assets. Although planned upgrades aim to sustain the Raptor’s relevance into the 2040s, its 1990s-era design imposes inherent limitations on further modernization, particularly in areas such as operational range, thermal management, and stealth maintenance. The NGAD Vision and Engine Innovation To overcome these challenges, the NGAD program seeks to deliver a comprehensive family of integrated next-generation systems, including the manned F-47 and unmanned Collaborative Combat Aircraft. Central to the F-47’s capabilities will be its Adaptive Cycle Engine, engineered to enhance fuel efficiency by approximately 25 percent, extend operational range, and provide advanced thermal management to support increasingly power-intensive sensors and avionics. GE Aerospace has been pioneering variable- and adaptive-cycle engine technologies since the 1980s, leveraging decades of research and development. Although GE’s early variable-cycle engine for the F-22 program demonstrated superior performance compared to its competitor, it was ultimately deemed too risky for deployment at the time. With technological maturity now achieved, the Air Force regards the Adaptive Cycle Engine as critical to achieving a generational leap in fighter performance. Risks and Oversight Concerns Despite these ambitious goals, the F-47’s aggressive development schedule has attracted scrutiny. Boeing, which also oversees the B-52 upgrade program, has encountered significant delays and cost overruns in that effort, raising questions about its capacity to meet the stringent deadlines associated with the F-47. These challenges underscore the inherent risks of the program’s accelerated timeline and highlight the necessity for rigorous oversight as development advances.
