The Hawker 4000, originally known as the Hawker Horizon, is a super-midsize business jet developed by Hawker Beechcraft (formerly Raytheon Aircraft Company). The Hawker 4000 received its certification from the Civil Aviation Administration of China in December 2009. In February 2010, Hawker Beechcraft delivered its first Hawker 4000 to a customer in mainland China. Production of the Hawker 400 began in 2010 and ended in 2013, with less than 180 aircraft being built.
The Hawker 4000 can be outfitted to seat ten people. The aircraft's carbon composite construction gives it more interior space than many jets in its class. Interior standing room is an average of six feet. This composite construction also makes the aircraft lighter than a standard aluminum structure, allowing a maximum range of 3,445 nautical miles, and a service ceiling of 45,000 feet (14,000 m). The flight deck features a Honeywell Primus Epic avionics suite with EICAS, FADEC and autothrottle.
