More Than a Makeover: The GE Aerospace 747 Flying Test Bed Sports a New Look
In the world of aviation, progress is often measured in thrust, efficiency, and cutting-edge materials. Yet, sometimes, a fresh coat of paint can signify a transformation just as profound. This is the case with GE Aerospace’s Boeing 747-400 Flying Test Bed, a critical asset in jet engine development, which recently received a new livery. This isn’t merely a cosmetic update; it’s a visual declaration of a new era for GE Aerospace, which became an independent, publicly traded company in 2024. The new design reflects the company’s forward-looking vision and its pivotal role in shaping the future of flight.
The marvel of air travel is built on a foundation of relentless testing and innovation, much of which occurs out of the public eye. At GE Aerospace’s facility in Victorville, California, a unique team is tasked with pushing new engine models to their absolute limits. Their primary tool is this specially modified Boeing 747, a veritable laboratory in the sky. By replacing one of its four standard engines with a test model, engineers can gather invaluable data in real-world flight conditions, a process essential for certifying the engines that power global air travel. This airborne workhorse has been instrumental in the development of industry-defining engines, and its new look heralds a busy future of continued innovation.
A Legacy of Testing and a Vision for the Future
The current Flying Test Bed, a former Japan Airlines Boeing 747-400 registered as N747GF, was acquired by GE in 2010. It stepped into the formidable role previously held by a legendary Boeing 747-100, an aircraft that started its life with Pan American World Airways in 1970. That predecessor, known as the Clipper Ocean Spray, was instrumental in testing over 11 different engine models, including the powerful GE90. When it was retired, it was one of the oldest 747s still in active service. The transition to the more modern 747-400 platform brought enhanced capabilities and more advanced integrated systems, allowing GE to continue pushing the boundaries of engine performance.
The new livery is a direct reflection of GE Aerospace’s new chapter as a standalone company. The design features a clean white fuselage that transitions into a striking “Atmosphere Blue” on the tail, bisected by a sharp diagonal line. The iconic GE Monogram is proudly displayed on the rudder. For the team in Victorville, this was more than a routine paint job. Renji Thomas, a site leader, sees it as “a visual representation of the ways in which the company has evolved.” It symbolizes a renewed identity and purpose as the company prepares for an anticipated increase in testing activities over the next decade.
This aircraft is far more than a flying billboard for the new brand. Inside, where up to 660 passengers might have once sat, the space is now filled with sophisticated computers and data acquisition systems. This flying laboratory allows engineers to monitor thousands of parameters in real-time, from engine pressures and temperatures to stress loads and vibrations. This capability was crucial for the certification of major engine programs like the CFM LEAP and the record-breaking GE9X. Since 2010, the 747-400 has logged over 1,500 flight hours dedicated solely to advancing engine technology.
“Everyone here is really energized by the new look. It was a different experience outside our normal operations here, but definitely a unique and exciting one.”, Jon Ohman, Chief Test Pilot for GE Aerospace
Pushing Boundaries in the Sky
The primary function of the Flying Test Bed is to create a controlled environment where new engines can be tested under the most demanding conditions imaginable. The stability and power of the four-engine 747 platform allow test pilots to safely push a single test engine to its operational limits and beyond. This includes high-altitude stalls, extreme weather encounters, and other scenarios that would be unthinkable on a commercial flight but are essential for ensuring safety and reliability.
Retired chief test pilot Phil Schultz, reflecting on the capabilities of the previous 747-100 test bed, noted its incredible efficiency, stating, “We can run five or six objectives in one flight and not come down and have to change everything between tests.” This ability to conduct comprehensive, integrated systems testing in the air is what makes the Flying Test Bed such an invaluable asset. It allows for the refinement of everything from fuel efficiency to control systems in a dynamic, real-world setting that ground tests simply cannot replicate.
The mission of the test bed is also evolving beyond engine certification. In a recent collaboration with NASA, the aircraft played a key role in the Contrail Optical Depth Experiment (CODEX) project. This research involved a NASA aircraft flying behind the 747 to study the formation of contrails, the ice crystal clouds that form in an engine’s wake, using advanced LiDAR technology. By creating three-dimensional images of these contrails, scientists hope to better understand and potentially mitigate the environmental impact of aviation, demonstrating the platform’s versatility in addressing the industry’s future challenges.
Conclusion: A Symbol of Continued Innovation
The new livery on GE Aerospace’s 747 Flying Test Bed is a powerful symbol of a company embarking on a new journey. It represents a fresh identity built on a long legacy of engineering excellence. This aircraft is not just a piece of history; it is an active and essential tool that is paving the way for the next generation of aviation technology. From certifying the world’s most powerful commercial jet engines to contributing to vital environmental research, the test bed is at the forefront of aerospace innovation.
As the aviation industry moves toward a more sustainable future, the role of platforms like the Flying Test Bed will become even more critical. The expected uptick in testing over the next decade points to a period of intense innovation, likely focused on enhancing efficiency, reducing emissions, and exploring alternative propulsion systems. The fresh look of N747GF serves as a reminder to the entire industry that GE Aerospace is not only ready for this future but is actively building it, one test flight at a time.

ISO-Gruppe Completes SKYcontrol Rollout for Penang Digital Tower
ISO-Gruppe has installed SKYcontrol at Penang International Airport, Malaysia’s first remote digital tower, ahead of a parallel run.
German IT specialist ISO-Gruppe has finished installing its SKYcontrol Tower electronic flight strip and ground surveillance system at Penang International Airport (PEN), the site of Malaysia’s first Remote, Digital and Virtual Tower (RDVT). The digital tower is due to take over aerodrome control as the airport’s conventional tower gives way to terminal expansion.
In an announcement dated November 3, 2026, ISO-Gruppe described the project as the first digital air traffic control in Asia. The company said the SKYcontrol Software Suite was fully installed and integrated into the existing infrastructure, and that the Remote Digital Virtual Tower Penang (RDVT Penang) will run alongside the existing tower system for about two months while controllers are gradually trained on the new digital processes.
What SKYcontrol replaces in the Penang tower
The installation has three core modules: SKYcontrol EFS, SKYcontrol Ground Track and SKYcontrol RCMS. According to ISO-Gruppe, numerous interfaces connect them to a camera-based virtual situational display, to flight data from the wider air traffic management system and to the airport’s stand allocation planning.
The Electronic Flight Strip System (EFS) fully replaces paper flight strips. Controllers get a digital interface for tracking and sharing flight data such as estimated arrival and departure times, routes and clearances, with weather, active notices to airmen (NOTAMs) and airfield lighting status added to support the coordination of approach and taxi movements.
SKYcontrol Ground Track, the ground and approach surveillance system, replaces the existing approach radar display. The company said it provides second-by-second landing tracking, departure detection and information on taxiing and parking, and records data for future planning. The RCMS module will let the maintenance team monitor system status continuously once the system moves into its maintenance and warranty phase after testing.
Why Penang is moving away from its conventional tower
Malaysia set out the background in an information paper, DGCA 61/IP/04/16, presented at the 61st Conference of Directors General of Civil Aviation for the Asia and Pacific Region, held in Kuala Lumpur from 7 to 11 September 2026. The paper says Malaysia began its first RDVT project at Penang in February 2025 as part of airport development, using an accelerated approach because the existing control tower sits on land needed for terminal expansion and line-of-sight limits restrict visibility.
The RDVT gives controllers a 270° to 360° panoramic, high-definition digital view without a fixed-height tower, which removes the need to build a new tower and frees land for capacity upgrades, according to the paper. Two camera masts with high-resolution digital cameras cover the airport to reduce blind spots. Penang has a single runway, 04/22, of 10,997 feet, according to the AirPro Atlas.
The timeline Malaysia reported
The paper lists the milestones. The RDVT facility building was completed on 4 April 2026, and system installation with site, user and final acceptance tests was completed on 15 June 2026. Controller operational training ran from 19 June 2026 to 10 July 2026.
A ghosting and parallel operations phase, in which the conventional tower’s operations are monitored from the RDVT facility, began in the week of 13 July 2026 and was expected to last a minimum of about two months. If assessments are satisfactory, the paper says, the ghosting phase is expected to finish by November 2026, with services then moving progressively to the RDVT. The existing conventional tower will be unavailable from December 2026 because of the expansion programme.
ISO-Gruppe said the project is now in its final Operational Readiness and Airport Transfer (ORAT) phase, and that other third-party systems, including video walls and voice communication systems, have already been accepted. The paper lists network redundancy, timely regulatory coordination, human factors assessment and operational readiness programmes as the key considerations Malaysia identified.
A second major Malaysian customer for ISO-Gruppe
“The total project duration of just 14 months demonstrates the maturity of our SKYcontrol platform,” said Stephan Schaer, Project Manager and Authorized Signatory at ISO Software Systeme GmbH. He called the project a major milestone that supports further expansion in the growing Asian aviation market.
“Penang Airport’s air traffic control is our second major customer,” said Marcel Bender, Technical Project Manager at ISO Software Systeme GmbH. The first is Kuala Lumpur International Airport (KLIA), a long-standing air traffic control client of the company. Beyond adapting the software to Penang’s requirements, ISO-Gruppe said it advised on operational process changes, including air traffic control clearance procedures.
AirPro News has also covered Avinor’s remote tower plan for Mo i Rana and a digital remote tower bid in North Carolina. ISO-Gruppe describes Penang International Airport as a key transport hub for northern Malaysia that handles passenger and cargo traffic. The airport is in the Bayan Lepas district, about 16 kilometers from George Town.

Wisk Aero Opens eVTOL Vertiport at Hollister Airport
Wisk Aero opens a purpose-built vertiport at Hollister Municipal Airport to test its autonomous Generation 6 eVTOL aircraft.
Wisk Aero has commenced operations at a new purpose-built vertiport at Hollister Municipal Airport in California, establishing a dedicated physical environment to test its autonomous Generation 6 electric vertical takeoff and landing (eVTOL) aircraft.
Announced in a company press release on October 30, 2026, following a ribbon-cutting ceremony the previous day, the facility will serve as a real-world testbed for precision landing technologies and terminal area flight procedures. The operational data gathered at the site will directly support the Federal Aviation Administration (FAA) eVTOL Integration Pilot Program (eIPP) and inform broader certification efforts for advanced air mobility (AAM) infrastructure.
Validating autonomous flight operations
The Hollister installation features a 100-by-100-foot vertiport pad designed to accommodate both piloted and autonomous operations. Wisk constructed the site using a modular design approach that incorporates elevated steel structures, integrated solar panels, and dedicated power banks. This modularity allows the infrastructure to be relocated for future testing requirements in other regions, such as Texas.
The transition from the project groundbreaking announcement on August 26, 2026, to the October 29 ribbon-cutting ceremony took approximately nine weeks. Local, state, and federal officials attended the opening event.
Wisk Aero Chief Executive Officer Sebastien Vigneron highlighted the operational necessity of the new site for the company’s testing program.
“Opening this vertiport for flight testing is a big moment for Wisk and the future of piloted and autonomous flight. Deploying our aircraft on a purpose-built vertiport gives us the exact physical setup needed to validate precision landing technologies and our complete autonomy stack,” Vigneron stated.
Hollister Municipal Airport Executive Director Jeff Crechriou noted that hosting one of the first on-airport vertiports capable of supporting autonomous operations positions the airport at the forefront of the AAM sector.
Regulatory alignment and infrastructure standards
The development of physical ground infrastructure remains a primary constraint for the eVTOL industry. Wisk built the Hollister facility to comply with existing FAA standards, intending to use the site to evaluate complex terminal area flight procedures. Testing will focus on missed approaches and precision landings, particularly in GPS-denied environments.
Vigneron noted that the site is designed to support all vertical takeoff and landing aircraft. The resulting data will feed into the FAA eIPP and the California Advanced Air Mobility Corridors Initiative, helping establish best practices for scalable vertiport integration.
This testing aligns with ongoing regulatory updates at the federal level. On October 22, 2026, the FAA released draft advisory circular AC 150/5390-4, titled “Vertical Flight Aircraft Infrastructure Design.” This document proposes new standards for pad sizes and approach paths, intended to replace the current interim vertiport design guidance and the existing heliport design circular. The FAA is accepting public comments on the draft until January 11, 2027. Data generated at the Hollister site could provide empirical support for finalizing these infrastructure standards.
Wisk corporate evolution and the Archer acquisition
The opening of the Hollister vertiport occurs during a period of significant corporate transition for Wisk Aero. Founded in 2019 as a joint venture between The Boeing Company and Kitty Hawk, Wisk became a wholly owned Boeing subsidiary in 2023. The company has focused exclusively on self-flying, all-electric air taxis, designing and building six generations of eVTOL aircraft and accumulating over 1,750 test flights.
The Generation 6 aircraft, designed as a four-passenger autonomous air taxi, completed its maiden flight in December 2025. The Hollister facility is specifically tailored to advance the flight testing program for this vehicle.
In August 2026, Archer Aviation reached a definitive agreement to acquire Wisk Aero, along with Insitu and SkyGrid, from Boeing. According to reporting by AVweb, the all-stock transaction will result in Boeing taking a nearly 20 percent equity stake in Archer. The deal is expected to close by the end of 2026, subject to regulatory approvals. The acquisition will consolidate Wisk autonomous technology portfolio under Archer while maintaining Boeing access to the technology through cross-licensing agreements.
AirPro News analysis
The rapid nine-week deployment of the Hollister vertiport highlights a strategic pivot within the AAM sector from vehicle design to the practicalities of ground infrastructure. While the industry has directed substantial capital toward aircraft certification, the physical bottlenecks of vertiport availability, power management, and standardized approach procedures remain critical hurdles for commercialization. By controlling its own test environment, Wisk can generate the specific operational data the FAA requires to finalize its pending vertiport design circulars. This empirical data gives the company a distinct advantage in shaping the regulatory framework that competitors will eventually have to navigate, particularly as the FAA transitions from interim guidance to permanent infrastructure standards.

Archer Aviation and ITA Airways Partner on Italy eVTOL Network
Archer Aviation and ITA Airways sign an agreement to launch an electric air taxi network in Italy, starting with Rome Fiumicino routes.
Archer Aviation Inc. and ITA Airways signed an agreement on October 29, 2026, to develop an all-electric air taxi network across Italy, marking the California-based manufacturer’s first partnership with a European airline.
The collaboration centers on deploying Archer’s Midnight electric vertical takeoff and landing (eVTOL) aircraft to connect major Italian cities and airports. According to a press release issued by Archer, the initial focus will be on routes connecting Rome Fiumicino Airport to Rome’s city center, targeting a reduction in travel time from a 60 to 90-minute ground commute to a zero-emission flight of less than 10 minutes.
Targeting urban congestion in Rome
Rome Fiumicino processed 50 million passengers in 2025, creating significant ground traffic between the airport and the urban core. The planned air taxi service aims to bypass this congestion using the Midnight aircraft, which is designed to carry four passengers and a pilot. The aircraft is optimized for back-to-back 20-mile trips with minimal charging time required between flights.
Archer Founder and Chief Executive Officer Adam Goldstein highlighted the market potential in the joint announcement, noting the infrastructure and regulatory environment in Italy.
“Italy is one of the most visited countries on Earth: Rome Fiumicino crossed 50 million passengers last year for the first time in its history. Every one of those travelers deserves the option to skip an hour in traffic with a 10-minute, all-electric flight.”
The manufacturer recently demonstrated the aircraft’s urban capabilities during piloted test flights in the San Francisco Bay Area. Those demonstrations included flights between Oakland and San Francisco’s Marina District, completing the route in approximately 10 minutes.
Expanding global airline partnerships
The agreement with ITA Airways expands Archer’s strategy of partnering with established commercial carriers to integrate eVTOL operations into existing passenger networks. The eVTOL market remains highly competitive, with manufacturers like Joby Aviation and Beta Technologies also advancing toward certification. Archer’s approach relies on utilizing the operational expertise and established customer bases of traditional airlines to drive early adoption of air taxi services.
ITA Airways, formed in 2021 following the restructuring of Alitalia, operates a modern Airbus fleet and serves over 70 destinations worldwide as part of the Star Alliance network. Joerg Eberhart, Chief Executive Officer and General Manager of ITA Airways, stated that the carrier intends to explore innovative solutions to strengthen connectivity.
“This agreement with Archer represents an important step in assessing how electric air taxi services could complement our network and enhance connections between airports, city centers and other strategic destinations.”
Archer has previously secured similar operational agreements with United Airlines in the United States and Abu Dhabi Aviation in the United Arab Emirates. In late October 2026, the manufacturer also announced plans for three air taxi networks in the Texas Triangle, connecting airports and business districts in Dallas-Fort Worth, Austin, and Houston.
Lufthansa Group integration and regulatory pathways
The partnership development occurs as ITA Airways undergoes a major ownership transition. The Italian Ministry of Economy and Finance currently holds a 59% stake in the carrier, with Deutsche Lufthansa AG holding the remaining 41%. Lufthansa finalized its initial acquisition in January 2025 and confirmed in May 2026 that it will exercise an option to increase its ownership to 90% following a €325 million investment. The transaction is expected to close in the first quarter of 2027, pending regulatory approvals from the European Commission and the US Department of Justice.
For the Italian air taxi network to materialize, Archer must secure certification for the Midnight aircraft from both the US Federal Aviation Administration (FAA) and the EASA. The aircraft cleared Phase 3 of the FAA’s four-stage certification process in April 2026.
The company is also advancing its regulatory path in other international markets. In May 2026, the UAE General Civil Aviation Authority (GCAA) transitioned the Midnight aircraft into a Restricted Type Certificate program, streamlining its path to operations in the Middle East.
AirPro News analysis
Securing ITA Airways as a European launch partner provides Archer with a critical foothold in a market heavily regulated by EASA. While the technological and certification hurdles for eVTOL aircraft remain high across the industry, aligning with a carrier that is actively being integrated into the Lufthansa Group offers Archer potential future access to one of the largest airline networks in Europe. We view this partnership as a strategic move to build operational credibility, though the timeline for commercial passenger flights in Rome will depend entirely on the pace of EASA validation and the construction of dedicated vertiport infrastructure.
