The Embraer EMB-505 Phenom 300, a light business jet designed and manufactured by Brazilian planemaker Embraer, is the most delivered private jet currently in the skies today. The aircraft is popular with operators for several reasons, including its ability to carry up to 11 passengers and the fact that it has been certified for single-pilot operations. Work on the Phenom 300 program began in the early 2000s in response to increased demand for an aircraft larger than the Phenom 100, a very light jet which had proven a bestseller.
