    Background
    Recent developments in electric motors, controllers, power generation and most importantly batteries have led to the development of hybrid gas-electric cars such as the Toyota Prius and Chevrolet Volt. These vehicles use a combination of energy storage in fossil fuels and chemical batteries to achieve their fuel efficiency, range, and performance goals. There are also fully electric cars such as the Chevrolet Bolt, Tesla Model S, and Nissan Leaf. The technology for batteries in the next decade will be challenged to store enough energy for longer range general aviation travel of 800-1000 nautical miles (nmi) alone.

    This Request for Proposal (RFP) is for the design of two-member Hybrid-Electric General Aviation Aircraft family. The entry into service (EIS) is 2028 for a 4-seat model with 1000 nmi of range and 2030 for the 6-seat model with 750 nmi of range. The intent is to have energy storage for takeoff, climb, go-around and emergencies via batteries and electric motors with an engine providing additional power and/or direct propulsion. Most aircraft manufacturers create a product that can cover the largest number of missions and markets with a minimum of non-recurring development costs and changes to a design. This results in the modification of an existing airframe to perform additional missions. The airframe and propulsion system commonality, by weight, between the 4-seat and 6-seat variant should be 75% or greater of the 4-seater's empty weight. Engine = internal combustion or jet engine Motor = electric motor powered by batteries or generated power Requirements (M) = Mandatory Requirement (T) = Tradable requirement
