FAA 5G Upper C-Band Mandates Impact Aviation Radio Altimeters
NBAA joins coalition addressing FAA’s new 5G Upper C-Band mandates requiring radio altimeter upgrades by 2029-2034 to prevent interference.
This article is based on an official statement from the National Business Aviation Association (NBAA) and regulatory filings regarding the FAA‘s January 2026 Notice of Proposed Rulemaking.
The National Business Aviation Association (NBAA) announced on January 16, 2026, that it has joined a broad coalition of industry stakeholders to address significant technical and logistical challenges posed by the Federal Aviation Administration’s (FAA) latest regulatory proposal. The FAA’s Notice of Proposed Rulemaking (NPRM), published on January 7, 2026, outlines strict new performance standards for radio altimeters to mitigate interference from future 5G telecommunications networks operating in the “Upper C-Band” spectrum.
This new regulatory push is driven by the “One Big Beautiful Bill Act” of 2025, federal legislation that mandates the auction of the 3.98–4.2 GHz spectrum band for commercial wireless use by July 2027. According to the NBAA, the aviation industry is now facing a tight timeline to develop, certify, and install next-generation equipment before these new wireless services go live, with initial compliance deadlines projected between 2029 and 2032.
The NBAA is collaborating with Airlines for America (A4A), original equipment manufacturers (OEMs), and the Radio Technical Commission for Aeronautics (RTCA) to ensure that the proposed rules are technically feasible within the mandated timeframe.
While the aviation industry spent much of 2022 and 2023 retrofitting aircraft with filters to protect against 5G signals in the “Lower C-Band” (3.7–3.98 GHz), the new mandate addresses a distinct and more complex challenge. The upcoming expansion involves the 3.98–4.2 GHz band, which sits significantly closer to the 4.2–4.4 GHz frequency range used by radio altimeters, critical safety instruments that measure an aircraft’s height above terrain.
According to technical details released in the NPRM, the proximity of these high-power wireless signals renders previous “filter-only” solutions insufficient. The NBAA notes that the new mandate will likely require the full replacement of radio altimeter units with new hardware designed to meet stricter Minimum Operational Performance Standards (MOPS).
A primary concern raised by the NBAA is the current lack of commercially available equipment to meet the FAA’s proposed standards. The industry is currently in a “solutions gap,” where the regulation demands performance specifications that manufacturers are still in the process of defining.
Heidi Williams, NBAA Senior Director of Air Traffic Services and Infrastructure, highlighted this discrepancy in the association’s statement: “The timelines proposed will be challenging in light of solutions that haven’t yet come to market… Achieving the proposed rule’s objectives, on any timeline, will require continued collaboration between industry stakeholders, the FAA and standards organizations.”
The FAA’s proposal sets a rigid schedule driven by the legislative requirement to auction the spectrum by July 2027. Based on the NPRM and industry analysis, the key milestones are as follows:
The FAA estimates that this rule will affect approximately 58,600 aircraft in the U.S. fleet. Industry estimates cited in the reporting suggest the total cost for these fleet-wide upgrades could exceed $4.5 billion.
The friction between the “One Big Beautiful Bill Act” and aviation safety highlights a recurring tension in modern infrastructure development: the pace of legislation versus the pace of engineering. Unlike the previous 5G rollout, where filters could be applied to existing hardware, the Upper C-Band expansion requires the invention and certification of entirely new avionics.
With the RTCA not expected to finalize the technical standards until March 2027, just months before the spectrum is legally required to be auctioned, manufacturers will be under immense pressure. If the standards are delayed, or if the certification process hits snags, the 2029 compliance window could close rapidly, potentially risking a repeat of the flight disruptions seen during the initial 5G rollout. The “collaboration” the NBAA speaks of is effectively a race to ensure the regulatory requirements do not outpace physical manufacturing capabilities.
To mitigate these risks, the NBAA is working closely with the RTCA Special Committee 239 (SC-239). In late 2025, this committee shifted its focus from producing a guidance document to developing a full Minimum Operational Performance Standard (MOPS). This shift is intended to ensure a robust, long-term technical solution that creates altimeters immune to the closer, more powerful 5G signals.
Airlines for America (A4A) echoed the need for cooperation in a statement regarding the new spectrum usage:
“We have been working collaboratively with the telecommunications industry, the FAA and the FCC to identify solutions that ensure our nation’s airspace remains safe while allowing the spectrum to be used.”
The FAA estimates the rule covers approximately 58,600 aircraft, including commercial airliners (Part 121), foreign carriers (Part 129), and business/general aviation aircraft equipped with radio altimeters.
General and business aviation operators have a compliance deadline set for two years after the initial commercial deadline. Based on current projections for 5G deployment, this places the business aviation deadline between 2031 and 2034.
The filters installed previously were designed for the “Lower C-Band” (3.7–3.98 GHz). The new legislation opens the “Upper C-Band” (3.98–4.2 GHz), which is much closer to the altimeter’s operating frequency. The existing filters cannot block interference from this adjacent band without degrading the altimeter’s performance, necessitating full unit replacement. Sources:

Summit Helicopters Acquires Blackcomb Helicopters Aviation Assets
Summit Helicopters acquires Blackcomb Helicopters’ fleet and sightseeing operations in BC, continuing services under the Blackcomb brand.
This article is based on an official announcement from Blackcomb Helicopters and additional industry reporting.
In a significant shift for the Sea-to-Sky aviation landscape, Summit Helicopters has officially acquired the aviation assets and sightseeing business of Blackcomb Helicopters. The deal, announced on January 22, 2026, transfers the operation of the region’s iconic sightseeing tours and utility contracts to Summit, a subsidiary of the Ledcor Group of Companies.
According to the official announcement from Blackcomb Helicopters, the transaction ensures that the “same friendly team” will remain in place to deliver services. While Summit Helicopters takes over ownership of the fleet and bases, the popular sightseeing tours will continue to operate under the established Blackcomb brand, preserving a name that has served the corridor since 1989.
The acquisition involves the transfer of Blackcomb Helicopters’ remaining fleet of seven aircraft, along with its operational bases in Whistler and Squamish, British Columbia. Summit Helicopters will now oversee a diverse range of mission profiles previously managed by Blackcomb, including:
In a statement regarding the transition, Blackcomb Helicopters emphasized the continuity of service:
“Summit will now operate our fleet of seven helicopters continuing Blackcomb’s work at our Squamish and Whistler bases in utility, film, firefighting, and emergency response – and will proudly continue to offer our popular sightseeing tours under the Blackcomb brand.”
— Blackcomb Helicopters Official Announcement
Peter Rice, Vice President of Summit Helicopters, welcomed the expansion, noting in industry reports that the move adds valuable talent and fleet assets to Summit’s operations, which already span Northern and Interior British Columbia, the Northwest Territories, and international markets.
This transaction marks the conclusion of a strategic restructuring for Blackcomb Helicopters under its previous owner, the McLean Group. Industry reporting indicates that this is the second phase of a two-part divestiture strategy executed over the winter of 2025–2026.
Prior to this asset sale, the McLean Group sold Blackcomb’s “Tourism Division”, specifically the Coast Range Heli-Skiing and Tyax Adventures brands, to Whitecap Alpine Adventures in December 2025. This effectively separated the adventure tourism marketing entities from the aviation operations. With the current deal, Summit Helicopters acquires the “hard assets”, the machines, hangars, and air operator certificates, necessary to fly the missions. Consequently, Summit is expected to act as the aviation provider for the tourism brands now owned by Whitecap, while simultaneously running its own utility operations.
Jason McLean, CEO of the McLean Group, reflected on the family’s tenure owning the operator since 2006. In a statement reported by industry sources, McLean expressed confidence in the new operators:
“After decades of specialized helicopter service which started in the Sea to Sky corridor and expanded throughout Canada, it is time for our family to make a change and pass Blackcomb Helicopters onto new operators. With shared values and commitment to always putting safety and premier customer experience first, we know our customers, our team and the communities we serve are in exceptionally good hands.”
— Jason McLean, CEO, The McLean Group
This acquisition reflects a broader trend of consolidation within the Canadian aviation sector. By absorbing Blackcomb’s Sea-to-Sky operations, Summit Helicopters (backed by the industrial giant Ledcor) secures a lucrative foothold in the Vancouver-Whistler corridor, complementing its existing strongholds in Yellowknife, Terrace, and Kamloops.
For the local market, the retention of the Blackcomb brand for sightseeing is a strategic move to maintain consumer trust. However, the operational shift to a larger corporate parent suggests a move toward greater economies of scale, likely necessary to buffer against the volatility of seasonal tourism and wildfire contract cycles.

Bombardier Global 8000 Gains EASA Certification for Ultra-Long-Range Jet
Bombardier’s Global 8000 business jet receives EASA certification, completing approvals for operation in key markets with top speed Mach 0.95 and 8,000 nm range.
This article is based on an official press release from Bombardier.
Bombardier has officially announced that its flagship aircraft, the Global 8000, received type certification from the European Union Aviation Safety Agency (EASA) on January 23, 2026. This approval marks the final major regulatory milestone for the ultra-long-range jet, clearing it for operation across all key western markets following earlier approvals in North America.
Marketed by the manufacturer as the “world’s fastest business jet,” the Global 8000 is designed to connect extensive city pairs such as London to Perth or Singapore to Los Angeles non-stop. According to the company’s announcement, this certification cements the aircraft’s entry into service, which officially began in December 2025.
The EASA certification completes a rapid sequence of regulatory approvals for the Canadian manufacturer. Data provided by Bombardier and aviation authorities confirms the following certification timeline:
Stephen McCullough, Executive Vice President of Engineering at Bombardier, highlighted the significance of the European approval in a statement regarding the program’s development.
“Attaining EASA certification illustrates the hard work and dedication of Bombardier’s highly skilled employees and suppliers… This accomplishment further strengthens the momentum behind this groundbreaking business jet.”
, Stephen McCullough, Executive VP of Engineering, Bombardier
The Global 8000 is positioned at the pinnacle of the business aviation market, primarily defined by its speed and range capabilities. The aircraft boasts a top speed of Mach 0.95 (approximately 729 mph) and a maximum range of 8,000 nautical miles.
Bombardier notes that the aircraft’s performance credentials were validated during flight testing in May 2021. During these tests, a Global 8000 test vehicle (FTV-5) broke the sound barrier, achieving a speed of Mach 1.015 in a shallow dive while utilizing Sustainable Aviation Fuel (SAF). This achievement allows the manufacturer to claim the title of the fastest civil aircraft since the Concorde.
Beyond raw performance, the press release emphasizes the aircraft’s focus on passenger wellness during ultra-long-haul flights. Key features cited by the manufacturer include: With the Global 8000 now fully certified in North America and Europe, the battle for dominance in the ultra-long-range segment intensifies. The Global 8000’s primary competitor is the Gulfstream G800. While both aircraft offer an identical range of 8,000 nautical miles, Bombardier has aggressively positioned the Global 8000 around the metric of speed.
The Global 8000’s top speed of Mach 0.95 edges out the Gulfstream G800’s Mach 0.925. While the practical time savings on a typical 12-hour flight may be marginal (estimated at 20 to 30 minutes), the marketing value of the “World’s Fastest” title is substantial in the elite tier of private-jets. Furthermore, Bombardier’s focus on cabin altitude, offering a slightly lower pressure altitude than competitors, suggests a strategy focused on “wellness and productivity” to appeal to executives flying 14-hour missions.

Honeywell and Flexjet Settle Dispute and Extend Engine Contract to 2035
Honeywell and Flexjet resolve litigation over engine maintenance delays and renew their HTF7000-series engine contract through 2035 with a $470M cash settlement.
This article is based on an official press release from Honeywell and Flexjet.
On January 21, 2026, Honeywell and Flexjet announced a comprehensive settlement to resolve all pending litigation regarding engine maintenance delays. The agreement not only ends a high-stakes legal battle that began in 2023 but also secures a long-term Partnerships between the two aviation giants. As part of the deal, the companies have renewed their Master Maintenance Agreement (MSA) for Honeywell HTF7000-series engines through 2035.
According to the joint press release, the settlement resolves all claims between the parties, including related litigation involving third-party maintenance providers StandardAero and Duncan Aviation. The deal allows Flexjet to secure guaranteed support for its fleet while enabling Honeywell to clear significant legal liabilities ahead of its planned corporate restructuring.
The settlement involves substantial financial considerations and service commitments. While the official press release emphasizes the renewed partnership, regulatory filings and company statements provide a clearer picture of the financial magnitude of the agreement.
Flexjet has characterized the total value of the settlement as exceeding $1 billion. This figure includes both “cash considerations and service credits,” which will likely be applied to future engine maintenance events. In contrast, Honeywell’s disclosures offer specific details regarding the immediate financial impact.
According to Honeywell’s SEC Form 8-K filings referenced in market reports, the settlement involves a one-time cash payment of approximately $470 million. Additionally, Honeywell expects to record a charge in the fourth quarter of 2025 that will reduce sales by approximately $310 million and operating income by roughly $370 million.
“We are pleased to have reached a resolution that supports our long-term growth and ensures the highest level of service for our customers.”
, Joint Statement from Honeywell and Flexjet
The renewed Master Maintenance Agreement covers the HTF7000-series engines, which power a significant portion of Flexjet’s mid- and super-midsize fleet. This extension guarantees maintenance support through 2035, providing Flexjet with operational certainty for the next decade. The conflict between the two companies originated from a 2019 maintenance agreement. In May 2023, Flexjet filed a lawsuit alleging that Honeywell had failed to meet contractual turnaround times for engine repairs and did not provide sufficient rental engines during maintenance events.
Flexjet’s legal filings claimed that these service failures led to significant aircraft groundings. At the peak of the supply chain crisis, reports indicated that up to 40 aircraft were parked due to a lack of available engines. Flexjet argued that Honeywell had prioritized new engine deliveries to original equipment manufacturers (OEMs) over supporting existing customers, a claim Honeywell contested.
The dispute escalated in 2025 when a New York court upheld the enforceability of a liquidated damages clause. This ruling exposed Honeywell to potentially massive liability, which analysts believe accelerated the push for a settlement before a jury trial scheduled for 2026 could commence.
The settlement serves distinct strategic goals for both organizations. For Flexjet, the deal secures the stability of its core fleet, which includes Bombardier Challenger 300/350 and Embraer Praetor 500/600 aircraft. The inclusion of service credits effectively subsidizes future maintenance costs, offsetting the financial impact of previous disruptions.
For Honeywell, the agreement removes a major legal distraction. The company is currently preparing for a spin-off of its Advanced Materials business. By resolving this litigation, Honeywell presents a “cleaner” investment profile to shareholders and avoids the unpredictability of a prolonged court battle.
We observe that this settlement is emblematic of the broader post-pandemic aerospace supply chain crisis. The dispute between Honeywell and Flexjet was not an isolated incident but a high-profile symptom of industry-wide shortages in skilled labor and critical parts, such as castings and forgings.
The structure of the settlement, heavy on “service credits”, is a common mechanism in aviation disputes. It allows the vendor to retain the customer’s business long-term while inflating the “headline value” of the compensation package without requiring an equivalent immediate cash outflow. For the industry at large, this agreement may set a precedent for how operators negotiate compensation for service failures, signaling that major OEMs are willing to pay a premium to avoid reputational damage and legal uncertainty during restructuring phases.
