The GreenJet is a Biogas-powered aircraft that will be used for commercial regional aviation. It runs on four eco-engineered turboprop engines that maximize fuel efficiency and minimize operation costs. We at Aster Aviation strongly believe that this will make a huge impact on the selected market, as the fuel used is widely available and cheap, the operation costs are very low, and it is very flexible in usage. Its 100-seater capability is higher than most regional airliners, and its engines are more powerful than its competitors. Its hybrid designed wings blends the aerodynamics of a swept-back wing and the lift of a straight wing to deliver maximum performance for the aircraft. It also features an advanced cockpit design, which ironically makes the plane easier to fly. All in all, this is the new breakthrough in aviation.
