Accelerate eVTOL Development with Comprehensive Regulatory Compliance

Flow helps agile, fast-moving teams bring electric Vertical Take-Off and Landing (eVTOL) vehicles to market efficiently while meeting stringent regulatory standards. Flow is designed to streamline your development process, ensuring compliance with essential technical standards and handbooks recognized by leading certification and regulatory authorities in the aviation industry:

  • FAA (Federal Aviation Administration) regulations and guidelines for eVTOL certification

  • EASA (European Union Aviation Safety Agency) standards for urban air mobility

  • DO-178C Software Considerations in Airborne Systems and Equipment Certification

  • DO-254 Design Assurance Guidance for Airborne Electronic Hardware

Flow supports you in transforming customer requirements into functional specifications, allocating these specifications to eVTOL systems, deriving performance criteria, and meticulously planning verification activities—all with end-to-end traceability. Whether you are developing a government project or launching a new eVTOL vehicle, Flow helps you maintain speed and efficiency while meeting all relevant regulatory standards.

Thomas Andrieu, Senior V&V Engineer @ Universal Hydrogen

"Flow is a game changer for us. With its simplified and easy to use interface, we can now quickly embark much more users than with traditional requirements management tools and this is key to have a "single source of trust" and avoiding disseminated and obsolete information."

"The platform allows us to efficiently manage all the requirements which are driving a complex, innovative and multi-level product like ours, it is the perfect tool when looking for agility and flexibility but while also focusing on structure and rigor."

"In my opinion, Flow is leading the new generation of system engineering tools, focused on user experience, performance and essential functionalities. Furthermore, the Flow team is regularly deploying new features based on users feedback and supports us very efficiently during the deployment of the solution to our company."

Modern eVTOL teams are moving to Flow

So Intuitive Engineers Actually Enjoy Using It

Traditional Requirements tools grind engineering to a halt. Flow is the easy to use alternative to clunky enterprise software where state of the art interface meets seamless asynchronous communication that keep work flowing.

Flexible to Match Your Existing Process

Designed to accommodate your agile team's needs with various configuration options and custom fields. Flow is streamlining your workflow, not replacing it.

No Onboarding or Training Required

Don't wait until the next failed stage gate review to implement Flow. Fully onboard your organization in 2 weeks. It's so easy to use we’ve never done a training session. Get started in minutes — evolve as you go
