Reviving the Electric Taxi: Green Taxi Aerospace Targets 2027 Certification

The aviation industry’s pursuit of emissions-free ground operations has received a renewed push. According to reporting by Leeham News, U.S.-based startup Green Taxi Aerospace (also known as Green Taxi Solutions) is advancing its “Zero Engine Taxi” system, with a firm target to achieve FAA certification by 2027. The company is initially focusing its retrofit solution on the Embraer E175 regional jet, a strategic move designed to capitalize on the high-frequency nature of regional aviation.

While the concept of electric taxiing, moving aircraft on the ground without using main engines, has existed for over a decade, previous attempts have struggled with weight penalties and commercial viability. Green Taxi Aerospace claims to have solved these engineering hurdles, backed by significant partnerships with Delta Air Lines, Embraer, and StandardAero.

Technical Breakthroughs and Weight Reduction

The core of the Green Taxi system involves installing electric motors inside the aircraft’s main landing gear wheels. These motors are powered by the aircraft’s existing Auxiliary Power Unit (APU), allowing the pilot to control speed and direction from the cockpit without engaging the main jet engines.

According to the Leeham News report, a critical differentiator for Green Taxi is the dramatic reduction in system weight compared to legacy attempts. Early iterations of electric taxi systems, such as the now-cancelled Safran/Honeywell EGTS project from 2013, added approximately 1,000 pounds to the airframe. This weight penalty often negated fuel savings during flight.

In contrast, Green Taxi CEO David Valaer, a former F-16 pilot, emphasized the advancements in modern power electronics.

“Ten years ago, the system weight was significantly heavier… ours weighs 20 pounds [referring to electronics].”

By driving the main landing gear rather than the nose wheel, the system also aims to provide superior traction, particularly in adverse weather conditions like snow or ice.

Strategic Partnerships and Funding

Green Taxi Aerospace has secured high-profile industry support to validate its technology. Leeham News notes that Delta Air Lines is providing operational data and testing support through its “Sustainable Skies Lab.” Additionally, the company has partnered with Embraer for technical validation on the E175 airframe and StandardAero to lead the certification process.

Financial backing for the development includes a $5.6 million grant from the FAA’s Continuous Lower Energy, Emissions, and Noise (CLEEN) program, highlighting federal interest in technologies that reduce airport noise and carbon footprints.

The Business Case for Regional Jets

The company argues that regional jets represent the ideal launch market. Because aircraft like the E175 perform frequent short-haul flights, they spend a higher percentage of their operating time taxiing compared to long-haul widebody aircraft. Green Taxi projects the following operational benefits:

  • Fuel Savings: A 5–20% reduction in fuel burn for short-haul flights.
  • Cost Efficiency: Estimated savings of $250,000 to $350,000 per aircraft annually.
  • Maintenance: Reduced wear on carbon brakes and lower risk of foreign object damage (FOD) to engines.

Why the “Main Gear” Approach Matters

We observe that Green Taxi’s decision to power the main landing gear, rather than the nose wheel, addresses a specific physics challenge that plagued competitors like WheelTug. The main gear carries approximately 90% of an aircraft’s weight. By applying torque there, the aircraft maintains better traction on wet or icy ramps, a critical requirement for airlines operating in winter climates. Furthermore, by targeting the retrofit market rather than waiting for new aircraft designs, Green Taxi opens an immediate addressable market of thousands of existing regional jets.

Timeline and Competitive Landscape

According to the timeline outlined in the report, Green Taxi plans to submit its certification plan to the FAA in late 2025, with a conforming prototype scheduled for assembly by mid-2026. If successful, the 2027 certification would place them ahead of other stalled initiatives.

The sector has seen high-profile failures, notably the Safran/Honeywell joint venture which ended in 2016 due to the aforementioned weight issues. Another competitor, WheelTug, utilizes a nose-wheel drive system but has faced repeated certification delays. Green Taxi aims to succeed by leveraging lighter modern electronics and a focus on regional aviation economics.

Japan Airlines Deploys Electric Aircraft Washing Robot at Narita

JAL will deploy the Aerowash AW3 robot at Tokyo Narita in 2026, cutting wash times 40% and water use 50%.

Published

on

Japan Airlines (JAL) will deploy a fully electric, remote-controlled aircraft washing robot at Tokyo Narita International Airport (NRT) later in 2026, a move projected to cut aircraft cleaning times by up to 40 percent and water consumption by half.

In a press release issued on August 28, 2026, the JAL Group announced the introduction of the Aerowash Remote-Controlled Aircraft Washing Robot (AW3), manufactured by Swedish firm Aerowash AB. The deployment marks the first time a domestic airline in Japan has implemented a program-controlled collaborative robot for aircraft exterior cleaning. The initiative aims to improve occupational health and safety for ground staff while reducing the environmental footprint of ground handling operations.

Operational efficiency and environmental impact

The AW3 is fully electric and battery-powered, eliminating direct exhaust emissions on the ramp during operation. According to the JAL Group, the automated system can reduce the time required to wash an aircraft by up to 40 percent compared to traditional manual methods. The robot is also expected to decrease water usage per aircraft by up to 50 percent.

Aviation Week reported that the AW3 system is compatible with several aircraft types in the Japan Airlines fleet, including the Boeing 737, Boeing 767, Boeing 787, and Airbus A350. Full-scale implementation at Narita is scheduled for late 2026 following comprehensive operational training for ground handling staff.

Labor strategy and Automation history

The aviation industry is increasingly turning to automated ground support equipment to mitigate labor shortages and improve turnaround times. Atsuki Kino of the Japan Airlines Airport Ground Handling Planning Department told The Straits Times that the primary objective is workload reduction rather than workforce elimination.

“The goal is not to reduce staff, but to reduce their workloads so they can use the time saved to perform other high-value tasks, changing the way they work,” Kino said.

The AW3 mitigates physical strain and chemical exposure for ground crews who previously conducted exterior washing manually. This is not the airline’s first attempt at automating exterior cleaning. According to Aviation Week, Japan Airlines tested a wired remote-controlled washing system in the 1990s. That initiative was ultimately abandoned due to technical limitations of the era, making the AW3 deployment a successful return to a concept first explored approximately 30 years ago.

AirPro News analysis

The introduction of the Aerowash AW3 by Japan Airlines highlights a broader industry shift toward electrifying and automating ground support equipment. As airlines face persistent global shortages in ground handling personnel, technologies that reduce physical fatigue and chemical exposure become critical retention tools. We expect to see similar collaborative robotics adopted across major Asian and European hubs over the next five years, particularly as Sustainability mandates force operators to scrutinize water consumption and ramp emissions. The 30-year gap between JAL’s initial wired prototype and the AW3 underscores how recent advancements in battery density and spatial programming were required to make automated aircraft washing commercially viable.
