Abstract: A system for maintaining a fleet of aircraft batteries located at multiple airports. The system may be configured to obtain charge information and battery health information for individual batteries within the fleet of aircraft batteries from charging containers located at individuals ones of the multiple airports. The charge information may include charge statuses of the individual batteries and/or the battery health information may characterize the degradation of the individual batteries over time. The system may determine predictions of one or more batteries to be re-allocated and/or to receive maintenance based on the battery health information. The system may generate a battery management plan including the one or more predictions recommending one or more batteries to be re-allocated and/or to receive maintenance.

Abstract: A parallel hybrid aircraft comprising an electric propulsion system and a combustion propulsion system. The electric propulsion system may include a motor, one or more batteries, and a first propeller. The combustion propulsion system may include a combustion engine and a second propeller. The combustion propulsion system may be decoupled and independently operable from the electric propulsion system. A flight control system may control which of the electric propulsion system and/or the combustion propulsion system provides propulsion and/or thrust for ground movement, takeoff, forward flight at cruising altitude, and/or landing.
