For the first time in many years the FAA has added a new category to its list, the Powered Lift category. It is defined as “Powered-lift. A heavier-than-air aircraft capable of vertical take-off, vertical landing, and low-speed flight, which depends principally on engine-driven lift devices or engine thrust for the lift during these flight regimes and on non-rotating aerofoil(s) for lift during horizontal flight.”
This comes in light of the very first civilian Tilt Rotor becoming a reality in 2020 when Era Aviation will accept its very first AW-609. We are entering the new decade at a very very very exciting time of aviation!
