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 can be outfitted to seat eight people in a comfortable cabin configuration. This is partially due to the aircraft's carbon composite construction, which 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 much 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.
