New Aircraft Sensors Detect Mid-Flight Ice to Improve Safety
Surrey Sensors and Certification Center Canada develop clog-free sensors to detect ice build-up, enhancing aviation safety and efficiency with helicopter applications.

Aviation safety is taking a significant step forward with the announcement of a groundbreaking aircraft sensor system designed to detect dangerous mid-flight ice build-up. According to an official press release from the University of Surrey, the new technology is a joint venture between UK-based Surrey Sensors Limited, a university Startups, and Certification Center Canada (3C).
The system aims to solve a fatal aviation hazard: ice accumulation that disrupts airflow, reduces lift, and blocks traditional pressure-based airspeed sensors. By utilizing clog-free technology that measures aerodynamic performance rather than just the presence of ice, the innovation promises to give pilots earlier and more reliable warnings.
Furthermore, the developers note that the sensors offer substantial environmental and efficiency gains by optimizing the use of energy-intensive anti-icing systems, while also opening new doors for Helicopters safety.
The Persistent Threat of Airframe Icing
Mid-flight icing remains one of the most significant weather hazards in aviation. Ice accumulation on an aircraft’s wings and fuselage destroys the smooth flow of air. This disruption increases drag and decreases the airfoil’s ability to create lift. Consequently, an aircraft experiencing severe icing may stall at much higher speeds and lower angles of attack than under normal conditions, potentially leading to an uncontrollable roll or pitch.
Compounding the aerodynamic danger is the risk of sensor failure. Traditional airspeed measurement systems rely heavily on pressure sensors, such as pitot tubes. In severe weather, these tubes can become blocked by ice, water, or debris, depriving flight crews of critical airspeed data and leading to fatal miscalculations.
Historical Context and Safety Data
The danger of aircraft icing is well-documented. According to historical accident data from the National Transportation Safety Board (NTSB) covering the period from 1982 to 2000, there were 583 civil aviation accidents and over 800 fatalities in the United States alone attributed to airframe icing. High-profile tragedies, such as the crash of American Eagle Flight 4184 in 1994, revolutionized how the industry handles supercooled large drops (SLD). However, maintaining sensor reliability in harsh conditions has remained a persistent challenge for aerospace engineers.
A Hybrid Approach: How the New Sensors Work
The newly announced system addresses these historical vulnerabilities through a hybrid technology that merges two distinct innovations into a highly robust, next-generation air data probe.
Micro-CTA and APM Technologies
The first core component is the Micro-CTA (Constant Temperature Anemometry) sensor, developed by Surrey Sensors Limited. According to the press release, these waterproof sensors are only millimeters wide and sit almost flush against the aircraft wing. Because they lack the traditional pressure holes found in pitot tubes, they are immune to clogging. Instead of measuring air pressure, they utilize heat transfer principles to measure airflow speed.
The second component is the Airflow Performance Monitor (APM), developed by Certification Center Canada. This system is designed to detect the physical effects of surface contamination, such as ice, on the aircraft. By combining these two approaches, the integrated system measures airflow speed near the surface of the wings as a rapid function of time. Rather than inferring the effect of ice from a distant sensor measurement, the system provides a direct, real-time picture of how ice or debris is actively altering the wing’s performance and stall margin.
“This technology is about giving aircraft a much clearer picture of what’s happening to their wings in real time. Combining different sensing approaches will help to make these measurements far more robust – particularly in the harsh conditions where current systems are most vulnerable. What’s important is not just detecting ice, but understanding how it is affecting the aircraft’s performance. That’s what allows for better, more reliable decisions in flight,” stated Dr. David Birch, Director of Research at Surrey Sensors and Head of the University of Surrey’s Centre for Aerodynamics, Aerospace and Automotive Engineering.
Industry Implications: Efficiency and Rotary-Wing Applications
Beyond immediate safety improvements, the new sensor technology carries significant implications for operational efficiency and Sustainability. Current anti-icing and de-icing systems are highly energy-intensive, drawing substantial power from the aircraft’s engines and thereby increasing fuel consumption. By providing precise, real-time data, the new sensor system ensures that anti-icing measures are deployed only when absolutely necessary. This optimization can save fuel and reduce overall emissions.
A Breakthrough for Helicopters
The technology also addresses a major blind spot in rotary-wing aviation. Currently, there is no widely available technology capable of measuring airflow over helicopter rotor blades in real time. Because the new Micro-CTA sensors are miniature and flush-mounted, they can be successfully applied to rotary environments.
“Knowing your stall margin in all phases of flight is critical. Combining these technologies will both further address this safety issue and open up new possibilities for a rotary environment. Together, Surrey Sensors Limited and Flight Test Centre of Excellence are poised to set new standards in aerospace safety, efficiency and environmental sustainability through innovative airflow sensing technologies,” said Alistair Chapman, Director of Marketing at Certification Center Canada.
Project Backing and Future Development
The development of this next-generation air data probe is an international collaboration backed by government funding from Innovate UK and the National Research Council of Canada. According to the project partners, the next steps involve moving toward flight testing to validate the miniature air data probe system in real-world aviation environments.
AirPro News analysis
We note that the transition from laboratory and wind-tunnel environments to active flight testing will be the critical proving ground for this technology. If the sensors perform as expected under real-world icing conditions, the ability to retrofit these flush-mounted, clog-free devices onto existing Commercial-Aircraft and regional fleets could significantly alter the aviation safety landscape. Furthermore, the application to helicopter rotor blades represents an untapped market that could drastically improve operational safety for search-and-rescue, medical, and offshore transport helicopters that frequently operate in marginal weather.
Frequently Asked Questions
What makes the new aircraft sensors different from traditional pitot tubes?
Traditional pitot tubes rely on pressure holes that can become clogged by ice, water, or debris. The new Micro-CTA sensors sit almost flush against the wing, have no holes, and use heat transfer principles to measure airflow, making them clog-free.
How does this technology improve fuel efficiency?
By providing precise, real-time data on how ice is affecting the aircraft’s aerodynamic performance, the system allows pilots to use energy-intensive anti-icing systems only when absolutely necessary, thereby reducing fuel consumption.
Can these sensors be used on helicopters?
Yes. Because the sensors are miniature and flush-mounted, they can be applied to helicopter rotor blades to measure airflow in real time—an application for which no widely available technology currently exists.

FAA Awards L3Harris Contract to Modernize US Airspace Through 2045
The FAA awarded L3Harris a contract to upgrade 700+ ground stations and operate the US aircraft tracking network through 2045.

On July 1, 2026, the Federal Aviation Administration (FAA) awarded L3Harris Technologies a contract to upgrade and operate the United States aircraft tracking network through 2045. The modernization effort will overhaul ground infrastructure to support the integration of advanced air mobility (AAM) vehicles and drones into the National Airspace System.
In a press release issued on July 1, 2026, L3Harris announced the agreement, which mandates the upgrade of at least 700 ground stations across the country. The enhanced network will provide real-time, satellite-based flight positioning data while bolstering cybersecurity measures to protect air traffic management systems. The exact monetary value of the contract was not disclosed.
Expanding surveillance for next-generation airspace
The contract extends the role of L3Harris in managing the FAA surveillance infrastructure for nearly two more decades. The upgraded ground stations are designed to handle increased network capacity, a requirement as the airspace becomes more crowded with non-traditional aircraft.
Kathy Crandall, President of Mission Networks, Space & Mission Systems at L3Harris, emphasized the operational impact of the upgrades.
“L3Harris is propelling the FAA’s modernization vision forward by delivering an advanced surveillance infrastructure that will define the future of our airspace system and ensure increased safety for all air travelers.”
Crandall added that expanding network capacity ensures the United States maintains its position in global air traffic management.
Alignment with broader FAA modernization initiatives
This surveillance contract aligns with ongoing FAA efforts to replace aging infrastructure across the National Airspace System. The agency has been executing its Facility Replacement and Radar Modernization (FRRM) strategy, which targets the replacement of over 370 air traffic control facilities and 618 radars that average 36 years of age.
L3Harris is already involved in parallel infrastructure projects for the FAA. The company is currently executing the FAA Telecommunications Infrastructure (FTI) upgrade. That project replaces legacy copper wire connections with high-speed fiber optic networks across FAA facilities, providing the bandwidth necessary to support emerging aviation technologies like electric aviation vertical takeoff and landing (eVTOL) aircraft and uncrewed aerial systems.
AirPro News analysis
The extension of the L3Harris mandate through 2045 highlights the reliance of the FAA on established defense and aerospace contractors to execute its long-term modernization goals. As the National Airspace System transitions to accommodate AAM and widespread drone operations, the data bandwidth and latency requirements for air traffic control will increase exponentially. We view the concurrent execution of the surveillance network upgrade and the FTI fiber optic rollout as a necessary synchronization. Without high-speed ground data transmission, the benefits of satellite-based, real-time tracking for low-altitude and autonomous aircraft would be severely bottlenecked.

FAA Proposes Supersonic Noise Standard to Repeal 1970s Ban
The FAA announced noise-based certification standards for supersonic overland flight on June 30, 2026, targeting final rules by mid-2027.

The Federal Aviation Administration (FAA) has proposed a new noise-based certification standard for supersonic aircraft, initiating the formal regulatory process to repeal the 1970s ban on commercial supersonic flight over United States territory.
Announced on June 30, 2026, by U.S. Transportation Secretary Sean P. Duffy and FAA Administrator Bryan Bedford, the rulemaking aims to establish acceptable noise thresholds for overland flights. The proposal provides aerospace Manufacturers with the regulatory framework required to finalize next-generation supersonic designs that utilize quiet boom and “Mach cutoff” technologies.
Regulatory framework and timeline
The initial proposal focuses on noise-based certification standards during cruise flight. According to the FAA press release, the agency plans to introduce a second rule covering landing and takeoff noise standards later in 2026. The FAA has set a target date of mid-2027 to finalize both sets of rules.
U.S. Transportation Secretary Sean P. Duffy characterized the initiative as a move to safely enable the next quantum leap in aviation technology. FAA Administrator Bryan Bedford noted that advances in aerospace engineering, materials science, and noise reduction will eliminate the traditional sonic boom.
“This means we can ultimately repeal the ban from the 1970s on supersonic flight over U.S. territory while minimizing noise impacts to residents in communities along the route and near airports,” Bedford stated.
The White House Office of Science and Technology Policy (OSTP) is also involved in the initiative. OSTP Director Michael Kratsios stated that the updated rules will strengthen the industrial base and ensure the future of aviation is built in America.
Technological foundations and industry response
The June 30 announcement follows a series of preparatory steps by both regulators and the aerospace industry. On January 27, 2026, the FAA unveiled a new agency structure that included the creation of the Office of Advanced Aviation Technologies, a division specifically tasked with overseeing the integration of supersonic aircraft into U.S. airspace.
The technical basis for the new noise thresholds draws on data from the NASA and Lockheed Martin X-59 quiet supersonic research aircraft. The X-59 completed its First-Flight on October 28, 2025. The aircraft was explicitly designed to reduce sonic booms to a gentle thump, providing regulators with the acoustic data necessary to establish new overland flight standards.
Commercial developers have responded positively to the regulatory clarity. Boom Supersonic CEO Blake Scholl confirmed that the FAA rulemaking includes provisions for the “Boomless Cruise” or Mach cutoff approach. Boom has been demonstrating this operational concept with its Boom XB-1 test aircraft. Scholl described the FAA announcement as a major step toward the supersonic renaissance.
AirPro News analysis
We view the establishment of a definitive noise standard as the single most significant regulatory hurdle for the revival of commercial supersonic travel. For the past several years, manufacturers have been developing quiet supersonic technologies without a finalized target for acceptable noise levels. By defining the Certification standards, the FAA is shifting the primary challenge for companies like Boom Supersonic from regulatory uncertainty to engineering execution. The mid-2027 target for finalizing both cruise and terminal area noise rules sets a tight timeline, but it aligns with the development schedules of the next-generation supersonic aircraft currently in testing.

Pilatus PC-6 Crash in France Kills 11 on Skydiving Flight
A Pilatus PC-6 crashed near Nancy-Essey aerodrome on June 28, 2026, killing all 11 aboard in France’s deadliest skydiving accident in 30 years.

This is a developing story. Information may change as official details are released.
This article summarizes reporting by the Associated Press, Reuters, and CBS News, alongside official statements from the Bureau d’Enquêtes et d’Analyses pour la Sécurité de l’Aviation Civile (BEA).
Eleven people sustained fatal injuries on June 28, 2026, when a Pilatus PC-6/B2-H4 Turbo Porter Commercial-Aircraft crashed shortly after takeoff during a skydiving flight in northeastern France.
The Accident occurred at approximately 09:00 UTC (11:00 local time) near the Nancy-Essey aerodrome (ENC/LFSN). According to French Transport Minister Philippe Tabarot, the event represents the deadliest general aviation accident involving skydiving operations in France in approximately 30 years. The Bureau d’Enquêtes et d’Analyses pour la Sécurité de l’Aviation Civile (BEA) has deployed four Investigations to the site to determine the circumstances of the crash.
Aircraft departure and impact
The aircraft, registered in Germany as D-FIPS and reportedly owned by Classic Wings GmbH, departed Nancy-Essey for a tandem skydiving excursion. Less than one minute after takeoff, the aircraft banked left and descended almost vertically, impacting a grassy area in the town of Tomblaine, approximately 300 meters from the runway.
The Meurthe-et-Moselle Prefecture confirmed that all 11 occupants died in the crash. The victims included one pilot, five skydiving instructors, and five students. Thierry Pechey, president of the Meurthe-et-Moselle branch of the Order of Independent Nurses, told CBS News that the students were local nursing colleagues participating in a first-time jump.
Local officials noted the aircraft crashed near a residential neighborhood and shopping center. Yves Séguy, Prefect of the Meurthe-et-Moselle department, told the Associated Press that the accident could have caused collateral casualties had the impact occurred just a few dozen meters away. No injuries on the ground were reported.
Safety investigation and witness reports
The BEA is leading the Safety investigation, working in coordination with the Paris Criminal Investigation Department and the Air Transport Gendarmerie Brigade (GTA). The official cause of the accident remains under investigation.
While the BEA has not confirmed any mechanical faults, Reuters reported that witnesses on the ground heard the aircraft engine noise stop suddenly before the descent. Hervé Féron, the mayor of Tomblaine, stated that the aircraft fell in an unexplained manner during its initial ascent.
French Interior Minister Laurent Nunez noted that families of the victims were present at the aerodrome and witnessed the accident, resulting in significant psychological trauma.
AirPro News analysis
We note that this accident follows another fatal skydiving flight earlier in June 2026 in Missouri, which resulted in 12 fatalities. While the two events involve different operators, aircraft types, and regulatory jurisdictions, the proximity of these high-fatality accidents will likely bring renewed regulatory scrutiny to general aviation skydiving operations globally. The Pilatus PC-6 involved in the Tomblaine accident was 35 years old, a common age for utility turboprops in the skydiving sector, where aircraft are subjected to high-cycle operations characterized by rapid ascents and descents. The BEA preliminary report will be critical in establishing the sequence of events following takeoff.
