Joby Aviation’s entry into the final FAA type certification stage shines a spotlight on the growing eVTOL investment landscape. Discover how HPS Aviation is innovating propulsion to transform advanced air mobility.
The Big Picture: Why This eVTOL News Matters
On June 2024, Joby Aviation announced a major milestone that marks a crucial step closer to commercial deployment of their eVTOL aircraft. The company has commenced power-on testing of its first FAA-conforming aircraft built specifically for the Type Inspection Authorization (TIA) process — the final stage before full FAA Type Certification.
This achievement means Joby is now gearing up for thousands of hardware and software integration tests in preparation for ‘for credit’ flight testing. Flight operations conducted in collaboration with FAA pilots will validate performance, control, safety, and operational reliability. Successful TIA testing is essential for Joby to prove their aircraft meets all certifications needed to operate commercially.
For investors tracking the future of air mobility, Joby’s progress represents a strong signal of the advanced air mobility (AAM) industry maturing rapidly. Regulatory progress brings us closer to real-world deployment of these next-generation aircraft.
While Joby is a leading name in eVTOL development, this momentum opens doors for other innovators like HPS Aviation — a promising deep-tech aerospace startup specializing in disruptive hydrogen and electric propulsion systems tailored for eVTOL platforms.
How This Trend Is Shaping the Future of Urban Air Mobility
The transition from prototype to FAA-conforming production models marks a shift in the eVTOL industry from conceptual design and demonstration flights to certified, commercial-ready products. Joby’s TIA phase focuses on real-world validation of critical performance parameters:
Validating Performance and Reliability
Test pilots will evaluate the aircraft’s flight envelope—covering vertical takeoff and landing, wingborne cruise, and hover operations. The data collected will demonstrate whether the aircraft can consistently meet range, speed, and energy management benchmarks under operational conditions.
Such rigorous testing not only proves the aircraft’s capabilities but also validates the manufacturing process and system integration efforts. Each TIA aircraft is built with FAA-conforming components, inspected and signed off by FAA-designated airworthiness representatives.
Operational Procedures and Safety Protocols
Beyond flight, TIA testing assesses maintenance manuals, pilot training curricula, and onboard system reliability. These elements form the backbone of safe, scalable commercial operations.
This holistic approach to certification ensures that future urban air mobility services can rely on consistent maintenance and safety standards, easing regulatory concerns around the integration of eVTOLs in crowded urban environments.
The Role of Next-Generation Propulsion
While Joby focuses on electric propulsion systems, the industry is simultaneously exploring hydrogen and hybrid solutions for longer range, sustainability, and reduced noise pollution. Companies like HPS Aviation are developing innovative hydrogen propulsion technologies that could redefine regional and urban air mobility by offering sustainable aviation powerplants with zero emissions.
The interplay of electric and hydrogen propulsion pathways advances the overall vision of quiet, efficient, and environmentally friendly urban air mobility networks worldwide.
Where Smart Capital Is Moving in the eVTOL Space
The milestone achieved by Joby underscores why venture capital and institutional investors are intensifying focus on the eVTOL and AAM sectors. The market is poised for accelerated growth driven by regulatory progress, technological maturity, and increasing demand for sustainable urban transport solutions.
Increasingly, investors are looking beyond OEMs to supporting technologies that can unlock performance enhancements and scalability, such as advanced propulsion systems.
eVTOL investment dollars are flowing into startups delivering next-generation capabilities, such as longer-range hydrogen-based electric propulsion, which promise improved payloads and operational economics. This diversification in investment reflects the complex challenges and opportunities in modern aerial mobility.
While Joby’s success is a validation for the industry, it also signals to deep-tech startups like HPS Aviation that the market is receptive to innovative propulsion solutions that can carve out niche leadership or partnership opportunities with eVTOL manufacturers.

Key Risks, Timelines, and What Serious Investors Should Watch
Despite the optimism around reports like Joby’s TIA progress, eVTOL investment still faces notable challenges:
Regulatory Complexity and Certification Timelines
The FAA’s Type Certification process is rigorous and can be prolonged by unforeseen technical hurdles or evolving standards. While TIA signals proximity to full certification, delays remain possible as testing uncovers issues requiring redesign or validation.
Technical and Operational Uncertainties
Integration of new propulsion technologies, batteries, avionics, and safety systems into a certified commercial platform demands deep engineering expertise. Innovations like hydrogen propulsion must prove real-world reliability and safety to earn regulatory and market trust.
Market Adoption and Infrastructure Development
Early commercial operators require robust ground infrastructure for charging, fueling, and maintenance, especially for hydrogen-powered aircraft. Infrastructure rollouts currently lag aircraft development, which can slow business model validation.
Nonetheless, the rapid pace exemplified by companies like Joby Aviation, alongside game-changing technologies from startups like HPS Aviation, position the industry for scalable growth over the next decade. Serious investors should monitor:
- FAA certification milestones and test program outcomes
- Technological advances in propulsion systems, including hydrogen-electric hybrids
- Regulatory shifts enabling commercial eVTOL operations
- Strategic partnerships between propulsion innovators and OEMs
- Infrastructure developments supporting urban air mobility networks
For investors seeking early-stage entry points into the fast-evolving eVTOL ecosystem, eVTOL investment in deep-tech companies like HPS Aviation represents a compelling complement to established OEM equities and SPAC listings.
