Gulfstream Aerospace delivered the 200th G600 to a customer, the Savannah, Georgia aircraft manufacturer announced today. Handed over to an unnamed customer in North America, the milestone aircraft was outfitted at Gulfstream’s facility in St. Louis.

The delivery took place nearly seven years after the ultra-long-range business jet entered service. To date, the G600 fleet has logged more than 197,000 flight hours and completed 87,000 landings, picking up 95 city-pair speed records along the way.

Earlier this year, the aircraft surpassed a more-than-decade-long record flying from Aspen, Colorado, to the UK’s London City Airport in 7 hours 42 minutes at an average speed of Mach 0.91. In January, the aircraft, along with its G500 sibling, had received EASA certification for steep-approach landing, clearing the way for operations at airports such as London City.

“Interest in the G600 remains incredibly strong worldwide as customers continue to be impressed with its remarkable capabilities,” said Gulfstream president Mark Burns. “Reaching the 200th delivery reflects the program’s continued momentum while reinforcing the aircraft’s proven maturity and reliability.”

Capable of accommodating up to four living areas and seating 19 passengers, the aircraft can fly 6,600 nm at Mach 0.85 or 5,600 nm at Mach 0.90. The G600’s Mmo is Mach 0.925.

Alto Aviation has released a new generation of Cadence cabin management system panels in touchscreen and M3 Metal formats for aftermarket cabin upgrades. The panels—designed for retrofit into business jets, turboprops, and VIP aircraft—are being introduced this week at the Aircraft Electronics Association Convention in Dallas.

Capable of controlling lighting, in-flight entertainment, power, galley appliances, attendant call, shades, climate, and system settings, the panels are available in 3.5- and 4.3-inch sizes for cabin applications and in a 10.1-inch galley touchscreen monitor. The panels’ graphical user interface is customizable and features power over Ethernet, and they fit in seat armrests, side ledges, bulkheads, and divans. M3 Metal switch panels can be fitted as independent units or paired with the touchscreen panels. A key feature of the Metal panels is that they do not show wear, according to Alto.

“This launch is a milestone for us,” said Scott Sweet, v-p of sales at Alto parent Heads Up Technologies. “We listened closely to our customers, and what they wanted was simple: modern controls that look beautiful, feel great to use, and integrate easily into older aircraft. Our new touchscreen panels and M3 Metal panels do exactly that. They bring today’s cabin experience to yesterday’s aircraft, and we’re genuinely excited to put this technology into the hands of operators, completion centers, and owners who deserve solutions that elevate every flight.”

NBAA has partnered with 4Air to expand its sustainable flight department accreditation program, the organizations announced ahead of the 2026 NBAA Schedulers & Dispatchers Conference, which opens tomorrow in Cleveland. NBAA created the accreditation program in 2022 to recognize business aviation organizations that are working to reduce environmental impact across flights, operations, ground support, and infrastructure. The partnership with 4Air will help expand the program through technical support, data verification, and environmental expertise.

“This program allows flight departments and businesses to demonstrate sustainability progress and leadership while helping move business aviation forward together to meet our industry’s unified goal of achieving net-zero carbon emissions in the years to come,” said NBAA president and CEO Ed Bolen.

The collaboration enables NBAA to expand the program while maintaining transparency and measurable outcomes, according to the organizations. 4Air characterized the partnership as reflecting the sector’s movement toward verified, data-based sustainability approaches.

4Air COO Nancy Bsales said the partnership reflects a shared belief that progress comes from practical frameworks helping flight departments embed sustainability into daily operations. “At this stage in aviation’s sustainability journey, leadership is defined by structure, data, and accountability,” she said.

Three dozen companies have earned the accreditation, including American Express, Coca-Cola, Gulfstream Aerospace, Humana, Pfizer, Target, Textron Aviation, and Whirlpool.

NASA’s X-59 supersonic demonstrator returned to the skies on Friday morning for a nine-minute flight that was cut short after a warning light illuminated. However, NASA officials said they were still able to gather data during the second flight from the aircraft built in collaboration with Lockheed Martin at its Skunk Works facility.

The aircraft first flew on October 28, reaching 12,000 feet and 200 knots. Plans for the second mission called for an hour-long flight that would expand the envelope to 20,000 feet and 225 knots. This would be followed by a series of successive flights to further expand the flight profile as it prepared to participate in the NASA Quesst program to examine the effect of quieter supersonic technologies.

The second flight was initially delayed after a caution light for a vehicle system went off at around 10 a.m. Friday morning, according to Cathy Bahm, project manager for the low boom flight demonstrator at NASA’s Armstrong Flight Research Center in Edwards, California. The system was reset, and “we were good to go,” Bahm said.

At 10:54 a.m., the aircraft took off from Edwards Air Force Base in California, but landed at 11:03 a.m. after a separate, unrelated vehicle system warning illuminated. NASA has moved the aircraft back to the hangar to evaluate the issue and determine the path forward.

West Star Aviation has acquired DCJet, expanding its nationwide MRO footprint and strengthening its AOG support capabilities across the U.S.

“Accepting failure is the price you pay for pursuing your dreams, and I promise it’s worth the cost every time,” NTSB chair Jennifer Homendy said Friday during the second-day general session at the Women in Aviation International Conference in Dallas. Speakers at this session emphasized resilience, human connection, and the courage to try again after setbacks.

Homendy shared some personal failures with humility and humor—including a D+ in oral communications and an F in aerobics as a college freshman—before speaking about a career setback that shaped her path to leading the NTSB. In 2015, she pursued a board member position at the agency.

She urged attendees not to eliminate themselves from opportunities. “Too many of us say no to ourselves long before anyone has a chance to,” Homendy said. “Try again, and keep trying.”

Air New Zealand COO Alex Marren first joined startup People Express Airlines and then rose through operations roles at United Airlines, where she eventually became the carrier’s first female country manager, assigned to Greece in her early 30s. She emphasized the importance of asking for help and hiring people smarter than herself. “Sometimes simply walking into the room makes the path visible for someone else,” she said.

Business aviation manual and SMS software developer Nimbl has released a guide relating to the FAA’s streamlined Part 91 approval process for letters of authorization (LOA). The guide explains the benefits of the streamlined LOA process, identifies eligible operators, and details how to submit applications.

According to Nimbl, the guide provides steps operators can use to apply for multiple LOAs in a single submission, which can reduce approval timelines and compliance delays.

“We recognized that the LOA application process can be somewhat daunting for operators,” said Nimbl v-p of strategic partnerships Clément Meersseman. “By working closely with the FAA, manufacturers, training institutions, and stakeholders to support the development of a streamlined approach, it’s now possible for flight departments to secure multiple LOAs more efficiently.”

In October, the company introduced an emergency response plan (ERP) guide to help operators prepare for crises. The free guide helps business aircraft operators, including small flight departments, develop ERPs.

Airlines for Europe (A4E) and the European Regions Airline Association (ERA) have demanded changes to the European Commission’s ReFuelEU rules that mandate increased use of sustainable aviation fuel (SAF). In a joint report published on Thursday, the industry groups called for improvements to the system, which they said will make it “smarter and clearer.”

Core demands relate to ReFuelEU’s anti-fuel-tankering rule, how SAF documentation and alignment with the emissions trading scheme (ETS) are handled, and fuel supplier market behavior and pricing transparency. The ETS is the EU framework through which all industries are subject to cap-and-trade mandates requiring them to hold allowances for every tonne of carbon dioxide they emit.

According to A4E and ERA, the anti-tankering rule, which fines operators who cannot prove that they uplifted at least 90% of their required fuel from EU airports, creates an excessively heavy administrative burden and sometimes results in excessive fuel burn. The groups called for “more proportionate thresholds” for how much fuel has to be uplifted in the EU and a harmonized exemption framework.

The groups complained that “late and inconsistent” sustainability documentation, combined with “misalignment” between ReFuelEU and the ETS, can leave airlines subject to audit and prevent them from claiming emissions benefits from SAF they have paid for.

Executive Flight Training has purchased the first Tarbes 9.00 flight training device from One-G Simulation, the simulator manufacturer’s latest device, which replicates the Daher TBM 900 turboprop single. Located at the company's facility in Brookshire, Texas, the simulator is equipped with electronic control loading that provides control force feedback to the pilot, electrically actuated elevator trim, an overhead panel that replicates the actual airplane’s panel, and emulated Garmin primary and multifunction displays and other avionics features.

To model the aerodynamics and performance of the TBM 900, One-G Simulation flew a production airplane to derive empirical data, including real-world performance, control response, and systems behavior “that directly informs the simulator’s flight model and avionics fidelity,” according to the company. “This aircraft-based R&D methodology represents a significant evolution in One-G’s development process and will continue to drive ongoing software refinement as additional flight-test data is collected and integrated.”

“The Tarbes 9.00 gives us a true TBM 900 training platform,” said Executive Flight Training CEO Douglas Carmody. “The accuracy of the cockpit layout, control loading, and avionics allows our instructors to deliver realistic, scenario-based training that closely mirrors the aircraft. That level of specificity helps pilots build confidence and competence before they ever leave the ground.”
