Battery And Powertrain CertificationBattery and electric powertrain systems remain primary certification bottlenecks because those technologies have not previously been certified on aircraft, increasing the risk of approval delays.
Cash Burn And ExpensesRising research, development, and administrative expenses are widening operating losses and accelerating cash burn as production and certification scale, increasing the likelihood of additional capital raises.
Certification Timing UncertaintyUnclear timing for piloted transition flights and readiness for required testing raises the risk of certification delays that could slow commercial deployment and disappoint stakeholders.
