Skyryse Unveils Universal Emergency Autoland for Helicopters and Fixed-Wing Aircraft

In a significant development for general aviation safety, Skyryse has announced the introduction of a “Universal Emergency Autoland” feature for its SkyOS™ operating system. According to the company’s official announcement, this technology represents the world’s first emergency landing system designed to be aircraft-agnostic, capable of safely landing both fixed-wing airplanes and helicopters in the event of pilot incapacitation.

The new capability is designed to address a critical gap in current aviation safety technology. While automated landing systems like Garmin Autoland have existed for several years, they have been restricted to specific fixed-wing airframes. Skyryse states that their new system leverages the SkyOS platform to bring similar “panic button” safety to the vertical lift market, including helicopters which require complex stabilization and control inputs to land safely.

Skyryse has confirmed that the Universal Emergency Autoland feature will be a core component of SkyOS. The system is currently undergoing “for-credit” testing with the Federal Aviation Administration (FAA), with the first production aircraft, the Skyryse One, expected to begin shipping in 2026.

How Universal Emergency Autoland Works

The core promise of the Skyryse system is simplicity for the passenger during a crisis. According to the company, the system can be activated in two ways: manually, via a single tap on a touchscreen by a passenger, or automatically, if the system detects pilot unresponsiveness or erratic flight behavior.

Once engaged, Skyryse describes a fully automated sequence of events designed to bring the aircraft and its occupants to safety:

• Identification: The system immediately calculates the nearest suitable airport, factoring in runway length, current weather conditions, and fuel range.
• Communication: It broadcasts a distress situation to Air Traffic Control (ATC) and informs passengers of the plan.
• Navigation and Flight: The aircraft flies a safe route to the destination, avoiding terrain and obstacles.
• Landing and Shutdown: The system executes the landing, including the complex hover and set-down maneuvers required for helicopters, and completely shuts down the engine upon arrival.

Mark Groden, CEO of Skyryse, emphasized the user-centric design of the feature in the company’s announcement:

“If you have an incapacitated pilot, you’re probably going to be pretty stressed… It would be so much easier to have, basically, a shortcut button for the passenger to press, and then they can focus on other things.”

Bridging the Helicopter Safety Gap

The distinction between fixed-wing and rotary-wing automation is substantial. Landing a helicopter requires active management of stability across all axes, a task that has historically made retrofitting autopilots difficult. Skyryse claims to solve this through a triply-redundant fly-by-wire system that replaces traditional mechanical linkages.

Technical Implementation

According to technical details released by Skyryse, the system utilizes “advanced sensor fusion,” combining data from radar, lidar, and cameras. This suite allows the aircraft to perceive its environment in real-time, ensuring that it does not attempt to land on obstacles, even if GPS data is slightly inaccurate. While Skyryse has previously demonstrated fully automated autorotations (unpowered landings), this new feature is specifically designed for powered emergency landings where the engine is operational but the pilot is unable to fly.

Comparison to Existing Solutions

The announcement positions Skyryse as a competitor to established players like Garmin, whose Autoland system is the current industry standard for turboprops and light jets. However, Garmin’s solution does not support helicopters. Other manufacturers, such as Leonardo, are developing similar capabilities for specific models like the AW169, but Skyryse aims to offer a universal retrofit solution applicable to a wide variety of airframes, starting with the Robinson R66-based Skyryse One.

AirPro News Analysis

The introduction of a universal autoland system for helicopters marks a potential paradigm shift in general aviation safety. Historically, high-end automation has been the domain of expensive business jets. By designing SkyOS as an “operating system” rather than a bespoke avionics suite, Skyryse is attempting to democratize safety features.

If successful, this technology could significantly reduce accident rates in the helicopter sector, which statistically faces higher risks than fixed-wing aviation. The ability to retrofit this technology onto older airframes could also revitalize the legacy fleet, offering owners a safety upgrade that was previously impossible without purchasing a brand-new aircraft. However, the success of this rollout hinges on the FAA certification process, which is notoriously rigorous for fly-by-wire systems in general aviation.

Timeline and Availability

Skyryse has outlined a clear roadmap for the deployment of this technology. The company is currently pursuing a Supplemental Type Certificate (STC) for SkyOS. The first aircraft to feature the Universal Emergency Autoland will be the Skyryse One, a modernized version of the Robinson R66 helicopter.

According to the press release, the Skyryse One is expected to ship in 2026. The Universal Emergency Autoland capability is slated to be available at launch or shortly thereafter as a standard feature of the SkyOS platform.

Frequently Asked Questions

What aircraft will support Skyryse Universal Emergency Autoland?

The system is designed to be aircraft-agnostic, meaning it can be installed on both helicopters and fixed-wing airplanes. The first certified aircraft will be the Skyryse One (a modified Robinson R66).

How is this different from Garmin Autoland?

Garmin Autoland is currently certified only for specific fixed-wing aircraft (like the Piper M600 and Cirrus Vision Jet). Skyryse’s solution is the first to support vertical-lift aircraft (helicopters) in addition to airplanes.

When will this technology be available?

Skyryse expects the first production aircraft featuring this technology to begin shipping in 2026, pending FAA certification.

Green Taxi Aerospace Secures Critical FAA Concurrence for Electric Taxi System

Green Taxi Aerospace has achieved a significant regulatory milestone in its bid to decarbonize ground operations, receiving official concurrence from the Federal Aviation Administration (FAA) on its certification plan. This agreement validates the company’s roadmap for its “Zero Engine Taxi” (ZET) system, a retrofit technology designed to allow airliners to taxi without using their main jet engines.

According to the company’s announcement, this concurrence effectively “de-risks” the development program. By aligning with regulators on testing and compliance strategies before the final conforming prototype is built, Green Taxi Aerospace aims to avoid the costly re-engineering pitfalls that have plagued previous attempts at electric taxiing solutions. The approval clears the path for the company to transition from planning into detailed design and hardware fabrication.

The Plano, Texas-based startup, led by former F-16 pilot David Valaer, is targeting a Supplemental Type Certificate (STC) for the Embraer E175 regional jet by late 2027.

Regulatory Alignment Before “Cutting Metal”

In the complex world of aerospace certification, FAA concurrence is a vital “gate” event. It signifies that the regulator has reviewed and accepted the manufacturer’s proposed methods for demonstrating safety and airworthiness. For Green Taxi Aerospace, this means the specific tests and data required to prove the system is safe are now agreed upon.

CEO David Valaer emphasized the strategic importance of this patience-first approach in the company’s statement:

“We touch the APU, we touch the landing gear, we touch the pilot control system. It’s a very complicated project… We’re not going to cut metal until our data is approved by the FAA.”

, David Valaer, CEO of Green Taxi Aerospace

With the certification plan approved, the company has outlined its immediate schedule. Detailed design drawings are slated for completion by mid-2026, followed by the assembly of the first “conforming” prototype, built exactly to the certified design standards, in late 2026. Ground taxi tests on an Embraer E175 are scheduled to begin in 2027.

The “Zero Engine Taxi” Technology

The core of Green Taxi Aerospace’s innovation is a retrofit system that installs electric motors directly onto the aircraft’s main landing gear. Unlike traditional taxiing, which relies on the thrust of massive jet engines optimized for flight, the ZET system uses the aircraft’s existing Auxiliary Power Unit (APU) to power the wheels.

The APU is a small turbine engine located in the tail of the aircraft. While it burns fuel, it is significantly more efficient at ground speeds than main engines. By utilizing the APU, the aircraft can push back from the gate and taxi to the runway with its main engines turned off.

Projected Operational Savings

Green Taxi Aerospace has released data highlighting the potential efficiency gains for operators of the Embraer E175. Regional jets are the primary target because they perform frequent flights with high daily taxi times, maximizing the utility of the system.

According to company projections:

• Fuel Savings: Approximately 80,000 gallons per aircraft, per year.
• Cost Reductions: Estimated savings of $250,000 to $350,000 per aircraft annually, factoring in fuel and maintenance.
• Emissions: An 85% reduction in ground-level carbon emissions compared to single-engine taxiing.

Crucially, the system is designed to be lightweight. The company states the total system weight is under 300 lbs. This is a critical metric; if the system is too heavy, the fuel burned carrying the extra weight during flight could negate the savings achieved on the ground.

Strategic Partnerships

To navigate the certification process, Green Taxi has partnered with StandardAero, a major aerospace maintenance, repair, and overhaul (MRO) provider. StandardAero is leading the certification effort, a move Valaer describes as essential for credibility.

“This partnership with StandardAero positions us for success by aligning our innovative technology with a proven certification partner.”

Contextualizing the Competitive Landscape

While the concept of electric taxiing is not new, Green Taxi Aerospace’s approach attempts to solve the specific engineering hurdles that stalled previous ventures. In 2013, the EGTS joint venture between Safran and Honeywell attempted a similar main-gear concept. However, that system reportedly weighed over 600 lbs and required extensive airframe modifications, which ultimately destroyed the business case.

Green Taxi’s claim of a sub-300 lb system suggests significant advancements in electric motor density over the last decade. By keeping the weight low, they address the primary failure point of the EGTS program.

The company also faces different competition than its predecessors. WheelTug is developing a system that places motors in the nose gear. While this simplifies installation, the nose gear carries less weight, which can limit traction in icy conditions or on slopes. Green Taxi’s decision to power the main gear offers better traction but represents a more complex integration challenge.

Another alternative, TaxiBot, uses semi-robotic tugs to tow planes. While this requires no aircraft modification, it introduces logistical complexity at busy airports, as tugs must return to the gate after every departure. Green Taxi’s onboard solution avoids this congestion but places the capital cost and weight penalty directly on the airline.

With FAA concurrence now secured, Green Taxi Aerospace has cleared the first major hurdle in proving that a lightweight, onboard electric taxi system is not just theoretically possible, but commercially viable.
