Joby Aviation, Inc. has submitted all of its Certification Plans to the Federal Aviation Administration (FAA), marking further progress toward completing the third of five stages required to certify its electric vertical take-off and landing (eVTOL) aircraft for commercial use.

In the third stage of the FAA type certification process (Certification Plans), Joby specifies the tests, analyses, and design reports it intends to perform to demonstrate compliance with each safety regulation that applies to the company’s aircraft, as defined in the second stage (Means of Compliance).

In February, Joby became the first eVTOL company to complete the second stage of the certification process, after becoming the first to complete stage one and have its Certification Basis published in the Federal Register.

“Joby continues to lead the way on certifying eVTOL aircraft with the FAA, and today’s news is another step towards launching commercial service in 2025,” said Didier Papadopoulos, Head of Aircraft OEM at Joby.

Joby’s stage three submittals include about a dozen Area-Specific Certification Plans (ASCPs), which cover both hardware and software aspects of every system onboard the company’s five-seat eVTOL aircraft, including its flight controls, energy storage and distribution system, and propulsion system. In addition to submitting all of its ASCPs as expected, Joby has also submitted all other Certification Plans comprising the third stage of its aircraft type certification program, including detailed plans for aircraft cybersecurity and systems safety.

Joby celebrated the launch of production at its pilot production line in Marina, California, as the first aircraft built on the line which secured a Special Airworthiness Certificate from the FAA, clearing it to begin flight testing. The aircraft is expected to be delivered to Edwards Air Force Base as part of Joby’s contract with the U.S. Air Force worth up to $131 million.
