Some runways are measured in kilometres. Cligent Aerospace’s latest test flight needed barely more than two parked buses. On an unprepared dirt strip in June 2026, the Ahmedabad startup’s scaled hybrid-electric eSTOL demonstrator lifted off after a ground roll of just 22 metres — validating an aircraft architecture designed to make the runway itself optional, reported Republic World. Aviation Week, in its July 2026 business-aviation briefs, put the figure at takeoff “within 70 ft. from an unprepared airstrip” — 21.3 metres, consistent with the company’s claim, per Aviation Week.
The achievement matters because of what it unlocks. India has hundreds of underutilised airstrips and remote locations that conventional commercial aircraft simply cannot serve — no long paved runway, no airport infrastructure, no air service. Cligent’s answer is not a helicopter or an eVTOL, but a fixed-wing aircraft that borrows electric propulsion’s instant torque for the takeoff roll and a fuel-powered generator for everything after.
What the demonstrator proved
The scaled technology demonstrator completed 18 test flights in the June campaign, reported Startuppedia, validating the aerodynamic design, flight controls, structural integrity and the proprietary hybrid-electric propulsion architecture under real operating conditions. The test card went well beyond a gentle hop: operations in ambient temperatures touching 42°C, stable flight in winds near 30 km/h, takeoffs and landings from an unprepared strip barely wider than the wingspan, and aggressive manoeuvring with a maximum roll angle of 65 degrees. The campaign also covered envelope expansion and simulated failure conditions.
Those numbers are the company’s own reported test results, but the flight of a subscale demonstrator is independently documented, and the design direction — eight distributed electric motors providing blown lift across the wing, backed by an onboard generator for range — follows an established eSTOL formula being pursued globally by companies like Electra. The difference is that this one is being engineered in Ahmedabad.
The CL1000: nine seats, no airport required

The demonstrator is a stepping stone to the CL1000, Cligent’s full-scale hybrid-electric STOL aircraft. The company describes it as a clean-sheet design carrying up to nine passengers or 1.2 to 1.5 tonnes of cargo on regional routes of 800 to 1,000 kilometres — while needing less than 150 metres of ground for takeoff and landing, per Startuppedia. The company’s own site lists payload of 1,500–1,800 kg, range of 100–800 km and true STOL capability under 150 metres, according to cligent.com. (The range figures differ between the company’s site and press coverage — the numbers here reflect what each source states, not independently verified performance.)
The pitch is infrastructure-free aviation: cargo and logistics, medical transport and medevac from runway-less regions, mining and industrial logistics, humanitarian missions, and passenger hops between places where building an airport would never make sense. “If a truck can reach the location, the CL1000 can land there,” the company says. The defence angle is hard to miss too — a 1.5-tonne payload aircraft that needs 150 metres of dirt has obvious tactical airlift uses, and the company has noted interest from that direction.
Why eSTOL instead of eVTOL
The eVTOL industry has spent billions proving that vertical flight is brutally energy-hungry: hovering on battery power drains the pack before the mission really starts, which is why most electric air taxis top out at a few dozen kilometres of range. eSTOL takes the opposite bet. By using a wing for lift and reserving electric power for the short, high-thrust takeoff burst, the aircraft keeps the efficiency of fixed-wing cruise while shrinking the runway to a fraction of what a Cessna Caravan needs. Cligent claims the hybrid approach could push operating costs below one cent per mile against three to six cents for conventional utility aircraft, per defence.in — a company projection, not a demonstrated figure, but the physics behind the claim is sound.
Who is building it
Cligent Aerospace was founded by Harsh Joshi and Vivek Dhut, engineering graduates of Gujarat’s Parul University, and incubated at the university’s PIERC facility. Joshi spent around five years in Bengaluru’s aerospace startup scene, including stints at Azista Aerospace and GalaxEye Space, while Dhut brought structural-engineering experience; the team they have assembled draws on veterans of Lockheed Martin, HAL, Airbus, ATR and L&T Defence, with the company claiming over a century of combined aerospace experience, reported defence-blog and the company’s site. Backing comes from IIMA Ventures, IIT Mandi Catalyst, PIERC and deep-tech investors, and the company says it holds pre-orders and MoUs, with a full-scale flying demonstrator under construction and commercial operations targeted for 2029, per TechCircle — timelines and order claims that remain the company’s own statements for now.
India has never produced a homegrown aircraft OEM in this class. If Cligent’s 22-metre hop scales into a certified 150-metre aircraft, the country’s hundreds of dead airstrips stop being dead weight — they become the network.
