At 700 kilograms, Sylla 1.0 is now India's heaviest electric aircraft to demonstrate sustained vertical hover flight.
NEW DELHI: Bengaluru-based Sarla Aviation announced on July 1 the successful completion of flight trials for its Sylla 1.0 technology demonstrator, an electric vertical takeoff aircraft that has now logged over 18 hours of flight time across more than 500 test points. Conducted over six months at Taneja Aerodrome near Hosur, the trials focused on validating vertical lift, hover control and structural performance, core building blocks for India’s emerging air taxi ambitions.
At 700 kilograms Sylla 1.0 is now confirmed as the heaviest electric aircraft in India to achieve sustained vertical hover flight, ahead of competing prototypes from The ePlane Company and BluJ Aerospace that remain in ground testing or lighter weight classes. For a country just beginning to build out advanced air mobility, this represents a meaningful and tangible engineering achievement.
Built Lean And Fast
What makes this milestone particularly encouraging is the pace and efficiency behind it. Sarla Aviation moved from a design concept to a flying half-scale demonstrator in under a year, on a total programme budget of less than $`13 million, a fraction of what global eVTOL developers like Joby Aviation and Archer Aviation have spent over a decade of development. This capital efficiency reflects a genuine strength of India’s aerospace engineering talent pool, with around 30% of Sarla’s team drawn from established global eVTOL companies including Lilium, Volocopter and Wisk.
The company’s founders, CEO Adrian Schmidt and CTO Rakesh Gaonkar, both previously worked together at Lilium, bringing direct international eVTOL experience into a homegrown Indian venture. As Gaonkar noted following the trials, the programme was designed specifically to validate real-world engineering questions that simulations alone cannot answer and doing so at this pace and cost is a genuine point of pride for India’s aviation sector.
Strong Backing From Credible Investors
Sarla’s progress has attracted meaningful institutional confidence. The company has raised close to `$13.4 million across its funding rounds with backing from Accel, Zerodha founder Nikhil Kamath, Flipkart co-founder Binny Bansal and Swiggy co-founder Sriharsha Majety. Notably IndiGo Ventures, the venture arm of India’s largest airline, made a strategic investment in January this year, a strong vote of confidence from a major domestic aviation player that understands the sector’s operational realities better than most.
A Regulatory Environment That Is Actively Engaging
India’s civil aviation regulator has also taken a constructive, forward-leaning approach to this emerging sector. The DGCA has already issued a dedicated advisory circular for VTOL aircraft certification and established six specialised working groups covering everything from vertiports to crew licensing. Encouragingly, Nalwa Aero already secured India’s first Design Organisation Approval for a multi-seat eVTOL in September 2025, showing that the regulatory pathway for passenger-carrying platforms is genuinely open and functional, not merely theoretical. Sarla is now working through its own approval process in active coordination with the Ministry of Civil Aviation and DGCA officials.
There is also promising movement on the policy front, with industry body CII pushing to extend production-linked incentives to the broader eVTOL manufacturing ecosystem, while the civil aviation ministry explores classifying air mobility assets as infrastructure to unlock long-tenure financing.
A Practical Path to Commercial Use
While mass urban air commuting remains some years away, the near-term use cases being pursued are sensible and achievable. Airport shuttle routes, such as connecting Bengaluru airport to Electronics City in under 20 minutes instead of a two and a half hour drive, offer an immediately practical application. Medical evacuation is another strong early use case, with Sarla already partnering with Aeromed International and Bluedot Air Ambulance to explore rapid emergency transport that bypasses road congestion entirely. The company has also signed an MoU with the Goa government to explore coastal aerial tourism routes, showing a thoughtful phased approach to building demand.
Industry voices are similarly optimistic about the sector’s trajectory. Amit Dutta, who chairs CII’s Advanced Air Mobility task force, has pointed to public-private partnerships as a practical route to unlocking vertiport infrastructure using government land banks, a model that could meaningfully speed up ground infrastructure rollout across Indian cities.
A Strong Foundation for What Comes Next
While Sarla’s ambitious 2028 commercial launch timeline is undoubtedly aggressive by global standards, the underlying achievement of Sylla 1.0 stands on its own. It demonstrates that Indian aerospace teams can execute complex electric flight engineering rapidly, efficiently and to a genuine safety standard, backed by serious investors and an engaged regulator. As the company now works toward transition flight testing and formal type certification, this hover milestone offers a credible and encouraging foundation for India’s advanced air mobility journey.
