A small demonstrator aircraft lifted off a dirt airstrip in western India after rolling forward barely 22 metres – roughly the length of two school buses – in a test that has validated a technology an Indian startup believes could eventually reach places no conventional runway ever has.
Ahmedabad-based Cligent Aerospace confirmed it had successfully flight-tested a scaled version of its hybrid-electric eSTOL aircraft, with company-reported results showing stable operation in temperatures up to 42 degrees Celsius, performance in wind speeds up to 30 kilometres per hour, and a takeoff and landing carried out entirely from unpaved ground rather than a prepared runway.
eSTOL stands for electric short takeoff and landing, a category of aircraft that aims to combine the fuel efficiency and lower emissions of electric propulsion with the ability to operate from airstrips far shorter than those needed by conventional cargo planes or airliners.
Cligent Aerospace was founded in 2023 by aerospace engineers Harsh Joshi and Vivek Dhut, both graduates of Parul University in Gujarat. The company has built its team with veterans drawn from established aerospace organisations including Airbus, ATR, Lockheed Martin and India’s Hindustan Aeronautics Limited.
Joshi previously spent around five years in Bangalore’s aerospace startup scene, including stints at Azista Aerospace and GalaxEye Space, while Dhut brings a background in structural engineering paired with an MBA.
The duo is now working toward a full-scale aircraft, the CL1000, a hybrid-electric platform designed to carry up to nine passengers or as much as 1,500 kilogrames of cargo over routes of roughly 1,000 kilometres, while taking off and landing in under 150 metres – a fraction of the runway length required even by small regional airports.
The CL1000’s hybrid-electric design pairs battery power with a generator, allowing the aircraft to draw on electric propulsion for efficiency while sidestepping the range limitations that have constrained purely battery-powered aircraft, since current battery technology cannot yet store enough energy per unit of weight to match a fuel-burning engine’s range.
Cligent has said this configuration could push operating costs below one cent per mile, compared with roughly three to six cents per mile for a conventional aircraft such as the Cessna Caravan commonly flown on similar regional routes – a difference the company argues matters considerably given that fuel typically makes up 30 to 40 per cent of a regional operator’s total costs.
The recently completed scaled demonstrator flight represents the first stage of a three-phase development plan, which is intended to progress to a full-size electric-powered airframe before the complete hybrid configuration is introduced and the aircraft is scaled toward production.
India’s regional aviation gap gives the aircraft an obvious commercial opening even before any military use is considered. The country is the world’s fastest-growing aviation market and its third-largest by domestic passenger volume, yet large stretches of hill states, island territories, flood-prone districts and remote agricultural regions still lack the road connectivity that would otherwise link them to larger cities.
Hundreds of small or underused airstrips already exist across the country, left over from earlier aviation infrastructure or agricultural use, and Cligent has positioned the CL1000 as a way to put that dormant infrastructure to work for passenger transport, cargo logistics, medical evacuation and emergency response – all roles conventional aircraft cannot serve economically.
The company has already signed multi-million-dollar memorandums of understanding with regional logistics firms in India, an early sign of commercial interest even before the CL1000 itself reaches full-scale flight.
Short-runway capability also carries relevance beyond civilian connectivity, a point Cligent’s own leadership has acknowledged by linking recent company updates to defence innovation and dual-use technology.
Military forces have long prized aircraft that can operate from short, unprepared strips, since battlefield logistics rarely come with the benefit of a paved runway, and an aircraft able to move cargo, medical supplies or personnel into remote or contested terrain using only 22 metres of rough ground offers a flexible airlift option that conventional transport planes cannot match.
