Bridging the Gap: The VH-4T Hybrid Powerplant

Technical Specifications and Capabilities

According to the company’s specifications, the VH-4T is a 400 kW-class turbine hybrid-electric system designed to bridge the gap between traditional liquid fuel engines and fully electric propulsion. The system is built around a highly reliable Pratt & Whitney helicopter engine from the proven PW200 series (specifically the PW206/207), which boasts a history of over 17 million flight hours. The self-contained unit integrates the turbine engine, generator, inverter, and thermal management systems, providing continuous electrical power at 800 volts DC.

VerdeGo Aero states that the powerplant is compatible with conventional Jet-A, JP-8, and Sustainable Aviation Fuel (SAF). The company is currently shipping the research and development variant, the VH-4T-RD, which entered low-rate production in November 2025. This model delivers 375 kW of maximum continuous power, weighs 511 lbs (232 kg), and operates exclusively as a series hybrid.

A production-intent model, the VH-4T-415, is expected in 2027. The company notes this future variant will offer 415 kW of power, weigh 565 lbs (257 kg), and feature a single-fault tolerant series or parallel hybrid configuration. VerdeGo has already filed an Application for Type Certificate with the FAA (Part 33) for the production model.

“400 kW is a good fit for 5-7 person air taxis, eCTOL or eSTOL aircraft that carry up to 9 passengers, or cargo drones that carry greater than 1000 pounds of payload. The power density makes it a good fit for electric aircraft, both military and commercial applications, that are focused on high performance.”

The Battery vs. Hybrid Debate in Advanced Air Mobility

Overcoming the Battery Bottleneck

A central narrative in the electrification of aviation is the limitation of current battery technology. While fully electric aircraft offer zero-emission operations, batteries are roughly 25 to 70 times heavier than liquid fuel for the equivalent amount of energy, according to industry data cited in the release. This weight penalty severely restricts the range and payload of battery-only electric vertical takeoff and landing (eVTOL) aircraft.

VerdeGo Aero’s hybrid solution addresses this by utilizing liquid fuel or SAF to generate electricity on board. The company claims the VH-4T carries roughly 20 to 26 times more energy than the market’s leading battery packs. This hybrid approach allows aircraft to achieve 300 to 500 nautical miles of range, enabling regional missions that are currently impossible for battery-electric airframes.

“These are the people that are looking for performance overall. So they need to be an electric airplane for some reason… but they also need to have three, or four, or five hundred nautical miles of range behind that, that a battery may not be able to provide at this time.”

, Pat Anderson, CTO & Co-founder, VerdeGo Aero (via company press release)

Military Validation and the Path to Certification

U.S. Air Force Involvement and Testing

The development of the VH-4T has been heavily supported by the U.S. military. VerdeGo Aero was awarded a $9.7 million Small Business Innovation Research (SBIR) Phase III contract by AFWERX to mature the technology for the U.S. Air Force. This funding is aimed at creating long-range, high-payload uncrewed tactical aircraft that do not rely on heavy batteries.

To ensure safety and reliability, the VH-4T-RD has accumulated hundreds of hours of runtime. According to the press release, this includes a rigorous 150-hour durability test conducted for the U.S. Air Force, which mirrors FAA Part 33 certification requirements. Further testing was conducted at VerdeGo’s Hybrid Systems Integration Laboratory (HSIL) in Daytona Beach, utilizing high-frequency turbulence models to validate the system’s response to rapid, dynamic changes in flight loads.

AirPro News analysis

The shipment of the VH-4T-RD represents a tangible shift from theoretical hybrid-electric concepts to physical hardware integration. VerdeGo Aero’s strategy of leveraging a proven Pratt & Whitney core engine significantly de-risks the mechanical side of their powerplant, allowing them to focus on the complex electrical and thermal integration required for AAM.

Furthermore, the dual-use nature of this technology, serving both commercial air taxis and military UAS, provides a robust financial and operational runway. The $9.7 million AFWERX contract, combined with a $12 million Series A funding round in 2022 led by RTX Ventures (Pratt & Whitney’s parent company), demonstrates strong institutional and OEM confidence. However, with a current lead time of 9 to 12 months for ordering a unit, scaling production to meet the anticipated 2027 certification and subsequent high-volume demand will be the next critical hurdle for the company.

German IT specialist ISO-Gruppe has finished installing its SKYcontrol Tower electronic flight strip and ground surveillance system at Penang International Airport (PEN), the site of Malaysia’s first Remote, Digital and Virtual Tower (RDVT). The digital tower is due to take over aerodrome control as the airport’s conventional tower gives way to terminal expansion.

In an announcement dated November 3, 2026, ISO-Gruppe described the project as the first digital air traffic control in Asia. The company said the SKYcontrol Software Suite was fully installed and integrated into the existing infrastructure, and that the Remote Digital Virtual Tower Penang (RDVT Penang) will run alongside the existing tower system for about two months while controllers are gradually trained on the new digital processes.

What SKYcontrol replaces in the Penang tower

The installation has three core modules: SKYcontrol EFS, SKYcontrol Ground Track and SKYcontrol RCMS. According to ISO-Gruppe, numerous interfaces connect them to a camera-based virtual situational display, to flight data from the wider air traffic management system and to the airport’s stand allocation planning.

The Electronic Flight Strip System (EFS) fully replaces paper flight strips. Controllers get a digital interface for tracking and sharing flight data such as estimated arrival and departure times, routes and clearances, with weather, active notices to airmen (NOTAMs) and airfield lighting status added to support the coordination of approach and taxi movements.

SKYcontrol Ground Track, the ground and approach surveillance system, replaces the existing approach radar display. The company said it provides second-by-second landing tracking, departure detection and information on taxiing and parking, and records data for future planning. The RCMS module will let the maintenance team monitor system status continuously once the system moves into its maintenance and warranty phase after testing.

Why Penang is moving away from its conventional tower

Malaysia set out the background in an information paper, DGCA 61/IP/04/16, presented at the 61st Conference of Directors General of Civil Aviation for the Asia and Pacific Region, held in Kuala Lumpur from 7 to 11 September 2026. The paper says Malaysia began its first RDVT project at Penang in February 2025 as part of airport development, using an accelerated approach because the existing control tower sits on land needed for terminal expansion and line-of-sight limits restrict visibility.

The RDVT gives controllers a 270° to 360° panoramic, high-definition digital view without a fixed-height tower, which removes the need to build a new tower and frees land for capacity upgrades, according to the paper. Two camera masts with high-resolution digital cameras cover the airport to reduce blind spots. Penang has a single runway, 04/22, of 10,997 feet, according to the AirPro Atlas.

The timeline Malaysia reported

The paper lists the milestones. The RDVT facility building was completed on 4 April 2026, and system installation with site, user and final acceptance tests was completed on 15 June 2026. Controller operational training ran from 19 June 2026 to 10 July 2026.

A ghosting and parallel operations phase, in which the conventional tower’s operations are monitored from the RDVT facility, began in the week of 13 July 2026 and was expected to last a minimum of about two months. If assessments are satisfactory, the paper says, the ghosting phase is expected to finish by November 2026, with services then moving progressively to the RDVT. The existing conventional tower will be unavailable from December 2026 because of the expansion programme.

ISO-Gruppe said the project is now in its final Operational Readiness and Airport Transfer (ORAT) phase, and that other third-party systems, including video walls and voice communication systems, have already been accepted. The paper lists network redundancy, timely regulatory coordination, human factors assessment and operational readiness programmes as the key considerations Malaysia identified.

A second major Malaysian customer for ISO-Gruppe

“The total project duration of just 14 months demonstrates the maturity of our SKYcontrol platform,” said Stephan Schaer, Project Manager and Authorized Signatory at ISO Software Systeme GmbH. He called the project a major milestone that supports further expansion in the growing Asian aviation market.

“Penang Airport’s air traffic control is our second major customer,” said Marcel Bender, Technical Project Manager at ISO Software Systeme GmbH. The first is Kuala Lumpur International Airport (KLIA), a long-standing air traffic control client of the company. Beyond adapting the software to Penang’s requirements, ISO-Gruppe said it advised on operational process changes, including air traffic control clearance procedures.

AirPro News has also covered Avinor’s remote tower plan for Mo i Rana and a digital remote tower bid in North Carolina. ISO-Gruppe describes Penang International Airport as a key transport hub for northern Malaysia that handles passenger and cargo traffic. The airport is in the Bayan Lepas district, about 16 kilometers from George Town.

Wisk Aero has commenced operations at a new purpose-built vertiport at Hollister Municipal Airport in California, establishing a dedicated physical environment to test its autonomous Generation 6 electric vertical takeoff and landing (eVTOL) aircraft.

Announced in a company press release on October 30, 2026, following a ribbon-cutting ceremony the previous day, the facility will serve as a real-world testbed for precision landing technologies and terminal area flight procedures. The operational data gathered at the site will directly support the Federal Aviation Administration (FAA) eVTOL Integration Pilot Program (eIPP) and inform broader certification efforts for advanced air mobility (AAM) infrastructure.

Validating autonomous flight operations

The Hollister installation features a 100-by-100-foot vertiport pad designed to accommodate both piloted and autonomous operations. Wisk constructed the site using a modular design approach that incorporates elevated steel structures, integrated solar panels, and dedicated power banks. This modularity allows the infrastructure to be relocated for future testing requirements in other regions, such as Texas.

The transition from the project groundbreaking announcement on August 26, 2026, to the October 29 ribbon-cutting ceremony took approximately nine weeks. Local, state, and federal officials attended the opening event.

Wisk Aero Chief Executive Officer Sebastien Vigneron highlighted the operational necessity of the new site for the company’s testing program.

“Opening this vertiport for flight testing is a big moment for Wisk and the future of piloted and autonomous flight. Deploying our aircraft on a purpose-built vertiport gives us the exact physical setup needed to validate precision landing technologies and our complete autonomy stack,” Vigneron stated.

Hollister Municipal Airport Executive Director Jeff Crechriou noted that hosting one of the first on-airport vertiports capable of supporting autonomous operations positions the airport at the forefront of the AAM sector.

Regulatory alignment and infrastructure standards

The development of physical ground infrastructure remains a primary constraint for the eVTOL industry. Wisk built the Hollister facility to comply with existing FAA standards, intending to use the site to evaluate complex terminal area flight procedures. Testing will focus on missed approaches and precision landings, particularly in GPS-denied environments.

Vigneron noted that the site is designed to support all vertical takeoff and landing aircraft. The resulting data will feed into the FAA eIPP and the California Advanced Air Mobility Corridors Initiative, helping establish best practices for scalable vertiport integration.

This testing aligns with ongoing regulatory updates at the federal level. On October 22, 2026, the FAA released draft advisory circular AC 150/5390-4, titled “Vertical Flight Aircraft Infrastructure Design.” This document proposes new standards for pad sizes and approach paths, intended to replace the current interim vertiport design guidance and the existing heliport design circular. The FAA is accepting public comments on the draft until January 11, 2027. Data generated at the Hollister site could provide empirical support for finalizing these infrastructure standards.

Wisk corporate evolution and the Archer acquisition

The opening of the Hollister vertiport occurs during a period of significant corporate transition for Wisk Aero. Founded in 2019 as a joint venture between The Boeing Company and Kitty Hawk, Wisk became a wholly owned Boeing subsidiary in 2023. The company has focused exclusively on self-flying, all-electric air taxis, designing and building six generations of eVTOL aircraft and accumulating over 1,750 test flights.

The Generation 6 aircraft, designed as a four-passenger autonomous air taxi, completed its maiden flight in December 2025. The Hollister facility is specifically tailored to advance the flight testing program for this vehicle.

In August 2026, Archer Aviation reached a definitive agreement to acquire Wisk Aero, along with Insitu and SkyGrid, from Boeing. According to reporting by AVweb, the all-stock transaction will result in Boeing taking a nearly 20 percent equity stake in Archer. The deal is expected to close by the end of 2026, subject to regulatory approvals. The acquisition will consolidate Wisk autonomous technology portfolio under Archer while maintaining Boeing access to the technology through cross-licensing agreements.

AirPro News analysis

The rapid nine-week deployment of the Hollister vertiport highlights a strategic pivot within the AAM sector from vehicle design to the practicalities of ground infrastructure. While the industry has directed substantial capital toward aircraft certification, the physical bottlenecks of vertiport availability, power management, and standardized approach procedures remain critical hurdles for commercialization. By controlling its own test environment, Wisk can generate the specific operational data the FAA requires to finalize its pending vertiport design circulars. This empirical data gives the company a distinct advantage in shaping the regulatory framework that competitors will eventually have to navigate, particularly as the FAA transitions from interim guidance to permanent infrastructure standards.

Archer Aviation Inc. and ITA Airways signed an agreement on October 29, 2026, to develop an all-electric air taxi network across Italy, marking the California-based manufacturer’s first partnership with a European airline.

The collaboration centers on deploying Archer’s Midnight electric vertical takeoff and landing (eVTOL) aircraft to connect major Italian cities and airports. According to a press release issued by Archer, the initial focus will be on routes connecting Rome Fiumicino Airport to Rome’s city center, targeting a reduction in travel time from a 60 to 90-minute ground commute to a zero-emission flight of less than 10 minutes.

Targeting urban congestion in Rome

Rome Fiumicino processed 50 million passengers in 2025, creating significant ground traffic between the airport and the urban core. The planned air taxi service aims to bypass this congestion using the Midnight aircraft, which is designed to carry four passengers and a pilot. The aircraft is optimized for back-to-back 20-mile trips with minimal charging time required between flights.

Archer Founder and Chief Executive Officer Adam Goldstein highlighted the market potential in the joint announcement, noting the infrastructure and regulatory environment in Italy.

“Italy is one of the most visited countries on Earth: Rome Fiumicino crossed 50 million passengers last year for the first time in its history. Every one of those travelers deserves the option to skip an hour in traffic with a 10-minute, all-electric flight.”

The manufacturer recently demonstrated the aircraft’s urban capabilities during piloted test flights in the San Francisco Bay Area. Those demonstrations included flights between Oakland and San Francisco’s Marina District, completing the route in approximately 10 minutes.

Expanding global airline partnerships

The agreement with ITA Airways expands Archer’s strategy of partnering with established commercial carriers to integrate eVTOL operations into existing passenger networks. The eVTOL market remains highly competitive, with manufacturers like Joby Aviation and Beta Technologies also advancing toward certification. Archer’s approach relies on utilizing the operational expertise and established customer bases of traditional airlines to drive early adoption of air taxi services.

ITA Airways, formed in 2021 following the restructuring of Alitalia, operates a modern Airbus fleet and serves over 70 destinations worldwide as part of the Star Alliance network. Joerg Eberhart, Chief Executive Officer and General Manager of ITA Airways, stated that the carrier intends to explore innovative solutions to strengthen connectivity.

“This agreement with Archer represents an important step in assessing how electric air taxi services could complement our network and enhance connections between airports, city centers and other strategic destinations.”

Archer has previously secured similar operational agreements with United Airlines in the United States and Abu Dhabi Aviation in the United Arab Emirates. In late October 2026, the manufacturer also announced plans for three air taxi networks in the Texas Triangle, connecting airports and business districts in Dallas-Fort Worth, Austin, and Houston.

Lufthansa Group integration and regulatory pathways

The partnership development occurs as ITA Airways undergoes a major ownership transition. The Italian Ministry of Economy and Finance currently holds a 59% stake in the carrier, with Deutsche Lufthansa AG holding the remaining 41%. Lufthansa finalized its initial acquisition in January 2025 and confirmed in May 2026 that it will exercise an option to increase its ownership to 90% following a €325 million investment. The transaction is expected to close in the first quarter of 2027, pending regulatory approvals from the European Commission and the US Department of Justice.

For the Italian air taxi network to materialize, Archer must secure certification for the Midnight aircraft from both the US Federal Aviation Administration (FAA) and the EASA. The aircraft cleared Phase 3 of the FAA’s four-stage certification process in April 2026.

The company is also advancing its regulatory path in other international markets. In May 2026, the UAE General Civil Aviation Authority (GCAA) transitioned the Midnight aircraft into a Restricted Type Certificate program, streamlining its path to operations in the Middle East.

AirPro News analysis

Securing ITA Airways as a European launch partner provides Archer with a critical foothold in a market heavily regulated by EASA. While the technological and certification hurdles for eVTOL aircraft remain high across the industry, aligning with a carrier that is actively being integrated into the Lufthansa Group offers Archer potential future access to one of the largest airline networks in Europe. We view this partnership as a strategic move to build operational credibility, though the timeline for commercial passenger flights in Rome will depend entirely on the pace of EASA validation and the construction of dedicated vertiport infrastructure.
