When the mid-light Legacy 450, as Embraer calls it, was being engineered, the expected range stood at approximately 2,300 nm with four passengers on board. By the time the 450 was officially announced at the 2013 NBAA Convention in Las Vegas, the airplane's range had climbed to 2,500 nm after a slight increase in engine thrust. When Flying evaluated the 450 at the company's Melbourne, Florida, production facility recently, test pilots had already proven the machine capable of flying nearly 2,600 nm with the same load. Then, just to keep things interesting, Embraer recently announced another range boost to just over 2,900 nm, with a 329 nm reserve and no payload changes thanks to some minor wing alterations that made room for more fuel. Not wanting early-delivery 450 owners to be left behind (since the first aircraft left the factory in December 2015), the mod was announced as retrofittable at no cost.
