Hawker 4000
The Hawker 4000, originally known as the Hawker Horizon, is a super-midsize business jet developed by the Raytheon Aircraft Company (now Hawker Beechcraft).
Development
Originally announced in 1996 as the Hawker Horizon, the 4000 made its official debut in November 2005 when a development aircraft was displayed at the National Business Aviation Association (NBAA) convention. As of March 2007 orders totaled more than 130 aircraft, with deliveries scheduled to begin in June 2008. On December 2, 2005 NetJets signed an order for 50 of the new aircraft, the largest single commercial order in the history of Raytheon Aircraft. [1]
The Hawker 4000 is being certified to FAA FAR Part 25 standards, which places a five-year time limit on certification of a new transport category aircraft. The 4000 completed Function and Reliability Tests on May 25 2006 [2]. However, since the Part 25 five-year window expired May 31, 2006, the company filed an extension request to head off the possibility that the certification program would need to restart from the beginning. On November 21 2006 the company announced that the 4000 has received its FAA type certification[3]. Although FAA type certified , no Hawker 4000s have been delivered and the company has yet to obtain a production certificate for the aircraft.
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. [4] 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. [5] The flight deck features a Honeywell Primus Epic avionics suite with EICAS, FADEC and autothrottle.

Interior
The 72in (1.83m) stand-up cabin is 77.5in wide (1.97m). The flat floor runs the entire length of the cabin and leads to a 2.83m³ baggage compartment. Access to the baggage compartment during flight is through the cabin and on the ground is via the exterior of the aircraft.
The cabin can accommodate eight to twelve passengers. The eight-seat cabin is arranged with four pairs of club chairs with writing tables. The cabin air conditioning and pressurisation system is digitally controlled.
Cabin pressurization
The cabin pressurization at cruising altitude (43,000 feet) can be maintained at the equivalent of 6000 feet (1800 m) altitude versus 8000 feet (2400 m) on conventional aircraft. This can significantly improve passenger comfort when gas becomes trapped in the gastrointestinal tract, the middle ear and the paranasal sinuses.
