Boeing 737-10 Undergoes Critical Wet Runway Braking Tests in Roswell

Boeing has successfully conducted “wet runway” braking tests for the 737-10, the largest variant of the MAX family, as part of its ongoing Certification campaign. According to an official update from the Manufacturers, the tests were designed to evaluate the aircraft’s anti-skid system under challenging, low-friction conditions.

The testing took place in Roswell, New Mexico, a location chosen for its consistently dry climate, which allows engineers to control the testing environment precisely. By artificially flooding the runway, the engineering team could simulate severe weather conditions to ensure the jet’s braking systems perform safely before the aircraft enters passenger service. Boeing has reaffirmed its commitment to certifying the 737-10 in 2026.

Engineering a “Slippery Situation”

Landing a Commercial-Aircraft on a water-logged runway requires a highly sophisticated braking system. The primary goal of these tests was to demonstrate the efficiency of the 737-10’s anti-skid technology, which prevents wheel lock-up and maximizes stopping power on contaminated surfaces.

Starr Fowler, an aerodynamics performance engineer at Boeing, emphasized the safety implications of the testing in the company’s statement:

“This test contributes to the Safety of 737 by demonstrating how well the anti-skid system works, and how efficient it can be, especially during a wet or contaminated runway. We want a fully modulated system.”

To create the necessary conditions, the ground operations team utilized a convoy of water trucks to spray thousands of gallons of water across the airfield. This process required precise timing to ensure the water remained at the correct depth just as the test pilots brought the aircraft down.

Lauren Auerbach, a ground operations engineer, described the logistics required to execute the test:

“It’s a timed operation between us on the ground and the airplane in the sky so that they can land repeatably on a wet, but not flooded runway.”

Data Collection and Flight Manuals

Once the aircraft touched down, engineers monitored the skid behavior to verify that the system utilized the limited friction effectively. The team repeated the landing sequence over several days, testing brakes from two different suppliers under various weight configurations, including both light and heavy payloads.

Joshua Olson, an aerodynamics performance engineer, noted that the data collected during these trials directly impacts the final documentation pilots will use in service.

“The data will ultimately be the numbers that go into airplane flight manuals that the pilot sees, and this is going to be a very refined and predictable estimation of the performance that we see on this airplane.”

According to Boeing, the 737-10 test fleet has now accumulated more than 1,500 flight test hours. The company is currently working to secure type inspection authorization from the Federal Aviation Administration (FAA) to proceed with further certification credits.

AirPro News Analysis

While Boeing’s official release focuses on the technical success of the braking tests, the timing and location provide deeper insight into the program’s status. Flight tracking data indicates that the test aircraft, identified as tail number 1G002, deployed to Roswell in early October 2025. This confirms that despite broader delays affecting the program, standard certification testing is proceeding actively.

The 737-10 is critical to Boeing’s competitive strategy against the Airbus A321neo. With a capacity of up to 230 passengers, the -10 variant is designed to offer high-density seating for single-aisle routes. However, the program has faced significant schedule adjustments. Originally targeted for an earlier release, the certification timeline has shifted to 2026. This delay is largely attributed to a required redesign of the engine anti-ice (EAI) system to prevent potential overheating of the engine inlet cowl.

By completing standard milestones like wet runway testing now, Boeing appears to be clearing the “routine” regulatory hurdles so that the aircraft is ready for immediate certification once the specific EAI redesign is approved by regulators.

Frequently Asked Questions

What is the purpose of wet runway testing?

Wet runway testing certifies that an aircraft’s anti-skid system can effectively stop the plane on slippery surfaces without the tires locking up. It ensures the braking system modulates pressure correctly to maintain directional control and stopping power.

When will the Boeing 737-10 enter service?

Boeing has publicly committed to completing certification for the 737-10 in 2026, after which deliveries to airlines can begin.

How does the 737-10 differ from other MAX models?

Iberia Launches Starlink Wi-Fi With Two-Year Fleet Rollout

Iberia operated its first Starlink-equipped flight on June 23, 2026, beginning a two-year rollout across its fleet.

Published

Iberia operated its first commercial flight equipped with SpaceX’s Starlink satellite Wi-Fi on June 23, 2026, marking the beginning of a two-year fleet-wide rollout for the Spanish carrier.

The inaugural service, flown by an Airbus A330-300 from Adolfo Suárez Madrid-Barajas Airport (MAD) to São Paulo/Guarulhos International Airport (GRU), is part of a broader €6 billion investment strategy by the Airlines. According to a company press release, the deployment makes Iberia the first Spanish airline to offer Starlink’s Low Earth Orbit (LEO) connectivity to passengers.

Fleet modernization and Flight Plan 2030

The newly installed system provides maximum download speeds of 500 Mbps, allowing passengers to stream content and use connected devices throughout the flight. The first Commercial-Aircraft to receive the modification was an Airbus A330-300 registered as EC-MAA.

Iberia Director of Customer Experience Beatriz Guillén stated in the press release that the airline is focused on providing the fastest onboard internet connection currently available. She noted that gate-to-gate connectivity remains a priority for both business and leisure travelers.

“Furthermore, this project reflects our commitment to innovation and digitalisation, two key pillars of Flight Plan 2030,” Guillén said.

The Flight Plan 2030 initiative encompasses a €6 billion total Investments aimed at upgrading customer experience, advancing digitalization efforts, and modernizing the carrier’s fleet over the coming years. Iberia plans to progressively install the Starlink hardware across its remaining aircraft over a two-year period.

Broader IAG implementation and scheduling challenges

The Iberia deployment is one component of a massive connectivity upgrade across the International Airlines Group (IAG) portfolio. In November 2025, IAG announced a strategic Partnerships with Starlink to equip more than 500 aircraft across its subsidiary airlines, according to reporting by Business Travel News.

While Iberia is initiating its progressive installation, sister airline British Airways recently paused its own Starlink rollout. Simple Flying reported that British Airways equipped five Boeing 787-8 aircraft before halting installations until October 2026.

The pause is reportedly driven by a lack of available hangar space and a shortage of qualified engineers during the busy summer travel season. A British Airways spokesperson told Simple Flying that the airline remains on track to complete the installation program as planned. The representative explained that the pause was pre-planned to align Starlink embodiment with scheduled maintenance, thereby avoiding flight cancellations and customer disruption during peak demand.

AirPro News analysis

We note that the contrasting rollout paces between Iberia and British Airways highlight the logistical complexities of retrofitting active fleets. While the LEO satellite technology itself is proven and offers a substantial upgrade over legacy air-to-ground or geostationary satellite systems, the physical installation requires significant aircraft downtime. Airlines must carefully balance the competitive advantage of high-speed connectivity against the immediate revenue loss of taking widebody aircraft out of service during peak summer demand periods. The decision by British Airways to pause installations until the slower autumn season reflects a conservative capacity management strategy, a path Iberia may also need to navigate as its own two-year rollout progresses.

Aircraft Orders & Deliveries

Avolon Acquires 11 Airbus A321neo Jets from Frontier Airlines

Avolon acquires 11 A321neo delivery slots from Frontier Airlines, valued at US$1.425B, as the carrier reduces capital commitments after a 2025 net loss.

Published

on

Aircraft lessor Avolon Holdings Limited will acquire 11 Airbus A321neo aircraft originally ordered by Frontier Airlines, absorbing near-term delivery slots scheduled between November 2026 and June 2027.

The transaction was unanimously approved by the board of directors of Avolon parent company Bohai Leasing Co Ltd on June 30, 2026. The agreement allows the Dublin-based lessor to expand its narrowbody portfolio amid ongoing global supply chain constraints. For Frontier Airlines, the transfer reduces capital commitments following a financially challenging 2025 in which the United States-based ultra-low-cost carrier reported a net loss of US$137 million.

Transaction details and delivery timeline

According to a regulatory filing submitted to the Shenzhen Stock Exchange (SZSE), the 11 aircraft hold a combined list value of US$1.425 billion based on 2018 Airbus SE catalogue prices. The final purchase price remains confidential under the terms of the agreement.

The aircraft are scheduled to join the Avolon fleet between November 2026 and June 2027. These airframes are drawn from a November 14, 2021, order placed by Frontier Airlines for 91 Airbus A321neo jets.

Fleet strategy and market dynamics

The agreement highlights shifting fleet strategies among operators and lessors. Frontier Group Holdings, the parent company of Frontier Airlines, generated US$3.724 billion in revenue during 2025 but ultimately posted a US$137 million net loss. Offloading these near-term delivery slots provides the airline with a mechanism to adjust its capacity growth and financial obligations.

Avolon gains access to highly sought-after narrowbody aircraft. Original equipment manufacturer (OEM) delivery delays have constrained the supply of new aircraft, driving intense demand in the leasing market for fuel-efficient models like the Airbus A321neo.

AirPro News analysis

We view this transaction as a mutually beneficial realignment of assets driven by current macroeconomic pressures in the aviation sector. Frontier Airlines secures immediate relief from the capital expenditure required to induct 11 new aircraft over an eight-month period, which aligns with the carrier’s need to stabilize its balance sheet after its 2025 losses. Avolon secures premium, near-term delivery slots that are virtually impossible to obtain directly from Airbus at this stage. Given the persistent shortage of narrowbody lift globally, Avolon is well-positioned to place these aircraft with operators eager for capacity.

On July 2, 2026, the Federal Aviation Administration (FAA) and the U.S. Department of Transportation (DOT) announced $1.776 billion in infrastructure grants distributed across 46 states to fund runway rehabilitations, taxiway construction, and safety upgrades.

The specific funding amount was selected to symbolically align with the United States Semiquincentennial, marking America’s 250th anniversary. According to an FAA press release, the investments are designed to modernize the travel experience and ensure the national airspace system is prepared for future demand.

“What better way to celebrate America than investing in its future. We’re ushering in the Golden Age of Transportation and rebuilding our airport infrastructure is critical to making that vision a reality. Under President Trump’s leadership, we are building an aviation system worthy of our country’s incredible history,” U.S. Transportation Secretary Sean P. Duffy stated in the release.

FAA Administrator Bryan Bedford noted that the agency is prioritizing rapid and efficient grant issuance. Bedford stated the funding “modernizes the travel experience for American families, ensuring our Airports are safe and ready for the future.”

Major airport allocations across the United States

The grant program directs substantial capital to several major hubs for pavement and lighting projects. Denver International Airport (DEN) received the largest single allocation highlighted in the announcement, securing $88.8 million for pavement projects. In the Pacific Northwest, Boise Air Terminal/Gowen Field (BOI) was awarded $74 million to rehabilitate its runway, expand the apron, and upgrade visual guidance lights.

Other significant awards include $62.4 million for Baltimore/Washington International Thurgood Marshall Airport (BWI) to rehabilitate its runway and associated lighting systems, and $62.2 million for Houston William P. Hobby Airport (HOU) to support runway construction.

Additional funding targets infrastructure at coastal and tourist hubs. John F. Kennedy International Airport (JFK) received $47.6 million for taxiway construction and the reconstruction of an aircraft rescue and firefighting building. Orlando International Airport (MCO) secured $36 million for terminal, taxiway, and lighting rehabilitation, while Oakland International Airport (OAK) was granted $28.1 million for taxiway rehabilitation.

Broader modernization initiatives

The July 2, 2026, grant announcement follows a series of recent infrastructure and regulatory actions by the DOT and FAA. Secretary Duffy and Administrator Bedford have prioritized public visibility into these upgrades. In May 2026, the agencies launched the “Modern Skies” website, a platform designed to provide transparency on more than 10,000 air traffic control modernization projects across the national airspace system.

The infrastructure funding also ties into the DOT’s broader commemorative efforts. In March 2026, Secretary Duffy introduced the “Freedom Moves You” campaign, an initiative bringing historical imagery to major transportation hubs, including JFK, in conjunction with the America 250th celebrations.

On the regulatory front, the FAA recently advanced new operational frameworks. On June 30, 2026, the agency proposed rules to establish noise-based certification standards for civil supersonic flight over the United States, aiming to facilitate the operation of next-generation aircraft without producing a sonic boom.

AirPro News analysis

We view the symbolic $1.776 billion figure as a clear messaging strategy from the DOT, linking routine but necessary infrastructure spending to the broader national narrative of the Semiquincentennial. While the dollar amount is stylized for the occasion, the underlying projects address critical deferred maintenance at major hubs like DEN and JFK. The focus on runway and taxiway rehabilitation reflects an ongoing necessity to maintain safety margins and operational efficiency as passenger volumes continue to test the limits of existing airport infrastructure.
