Technical approach

As reported

Hybrid power

Battery plus fuel engine

Piston engine powers a generator; electric motors drive propellers; battery charges in flight.

Onboard charging

In-flight battery recharge with no ground infrastructure

Fuel engine recharges the battery during cruise; aircraft needs no ground charging infrastructure.

Proven aircraft

Retrofit of the Cessna Grand Caravan

The AMP-H570 retrofits the proven Cessna 208B, minimizing regulatory risk with a field-tested aircraft.

Upgrade path

Scalable to larger aircraft

The hybrid-electric core scales to turboprops and regional aircraft; STCs planned for multiple types.
