Solving Aviation’s Battery Problem
Description
Electrification is coming to aviation, but Ampaire’s CEO Kevin Noertker says the practical near-term path is hybrid-electric, not fully electric. In Hangar X, he explains how Ampaire shifted from bold sci-fi concepts to a certifiable retrofit strategy, proven in rugged deployments.
Episode Highlights
Big belief: Electrification will transform aviation like it did cars.
Pivot to hybrid: Full-electric retrofits proved the tech, but hybrids were faster to certify and sell.
Infrastructure bottleneck: Hawaii showed charging networks lag aircraft readiness.
How it saves fuel: Cruise-optimized combustion + electric boost for takeoff/climb.
Cert progress: FAA hybrid-engine certification + Eco Caravan STC path.
Safety gain: Dual power sources add graceful-degradation resilience.

About Speedbird Ampaire
Ampaire is a California aviation company building hybrid-electric propulsion and retrofit aircraft for existing turboprop fleets. Its flagship AMP-H570 “AmpDrive” combines a Jet-A piston engine with an electric motor/battery boost, flying on the Eco Caravan (hybrid Cessna Grand Caravan). The strategy targets near-term fuel and emissions cuts without depending on charging infrastructure.
