The Legacy 600 is based on the ERJ 135 model, with avionics from ERJ 140 model, includes added range with extra fuel tanks in the tail and forward of the wing, added winglets and an extensive drag reduction. It is certified to 41,000-foot (12,000 m) altitude versus 37,000 feet (11,000 m) for the airline configuration. The Legacy carries 16 passengers for 3,050 nautical miles (5,650 km) or 8 passengers for 3,450 nautical miles (6,390 km). The Legacy 600 competes on the upper end of the small to mid sized range of business jets. It has nearly the opposite design progression as the rival Canadair Challenger. The Legacy 600 was derived from the established ERJ family of regional jets. Both lines of aircraft are competitors. Embraer has since launched an extensive lineup of business aircraft, from the entry-level Phenom 100 to the Lineage 1000, a very-long-range business jet version of the company's 100-seat E-190. In seven years of service, Embraer have delivered over 150 Legacy 600 aircraft in more than 20 countries. It has seating for 13 passengers in three partitioned sections. In the cockpit, the Legacy also includes a Honeywel Primus 1000 avionics suite, with a fullglass cockpit.
