Hawker 800


The Hawker 800 is a mid-size twinjet corporate aircraft. It is a development of the British Aerospace BAe 125, and was assembled by Hawker Beechcraft.

Development

In April 1981, the British Aerospace board sanctioned the programme to improve the British Aerospace 125-700 series. By May 1983 the new aircraft was ready for its first test flight.
The BAe 125-800 series has a number of modifications and changes over the 700, the most noticeable being the redesigned cockpit windscreen. Accompanying this are a modified rear fuselage fairing, as well as a glass cockpit and uprated Garrett TFE731-5R-1H engines. British Aerospace also improved the wing by incorporating new outer wing sections. This helped to reduce drag and improve aerodynamic efficiency.
The 125-800 series would become a sales success. From the first BAe 125 flight in August 1961 it took nineteen years until the 500th airframe was sold. In a little over five years, British Aerospace were registering the 200th sale of the 800 series.
In 1994 Raytheon acquired Corporate Jets. The new entity being known as Raytheon Aircraft. In March 2007, Raytheon divested its aircraft manufacturing business to Hawker Beechcraft Corp., a company formed and controlled by GS Capital Partners and Onex Partners of Canada.
The last version was the Hawker 850XP, which was certified for operation in March 2006. The 850XP is identical to the 800XP except that it includes winglets, which have extended its operating range by. This version also incorporates upgraded avionics and a redesigned interior. The Hawker 850XP essentially fills the gap left behind by the Hawker 1000 when production of that aircraft ceased.
Two new variants were announced in October 2006 for future deliveries:
After the 2013 bankruptcy of Hawker Beechcraft, the surviving company, Beechcraft, discontinued its business jet range, including the 800 series, although the designs are still supported for parts.
By 2018, a 1980s-era 700s was priced for less than $500,000, a 1995 800A at $1.02 million and a 2012 900XP at $6 million.

Design

The Hawker 800 is similar to most modern airframes in requiring sub-assemblies to be constructed away from the final point of manufacture. The fuselage sections, wings and control surfaces are manufactured and assembled in the United Kingdom in a combination of Hawker Beechcraft's own facility and those owned by Airbus UK, which inherited much of BAE Systems's civil aircraft manufacturing capacity. These sections are partially fitted out and installed with control surfacing and major systems before being shipped to Hawker Beechcraft's main manufacturing site in Wichita, Kansas for final assembly, fitting out and testing.

Military variants

Japan uses a maritime search and rescue variant of the Hawker 800. It is designated the U-125A in Japan Air Self-Defense Force service. This variant has large observation windows, a flare and marker-buoy dispenser system, life-raft and emergency equipment dropping system and enhanced salt water corrosion prevention. The aircraft also has a Toshiba 360-degree search radar, Melco thermal imaging equipment and other military communications equipment for its mission.
A military version of the Hawker 800XP is in use by South Korea for tactical aerial reconnaissance, surveillance and SIGINT tasks, and 8 specially equipped aircraft were delivered in 2000. The Republic of Korea Air Force calls them RC-800s, and they are based at Seoul Air Base.

Variants

With 48 built, this lower-cost, lighter-weight and shorter-range version of the 800XP competes with the Citation XLS and Learjet 60.
In November 2017, used prices range from $2.2 million for early 2008 models to 3.8 million for late 2011 models.
Its larger cabin is typically configured with eight seats in double club or a four chair club followed by a three-place divan facing a single seat, and is pressurized by to provides a cabin altitude at FL 410.
Its ventral fuel tank is replaced with a external baggage compartment, leaving of fuel in the wet wings.
The cockpit has four-screen Rockwell Collins Pro Line 21 avionics and FMS-6000.
It takes off in at MTOW/Sea level.
With a 20° quarter chord wing sweep, its maximum speed is Mach 0.80, it cruises at Mach 0.74 to 0.78 and long-range cruise is Mach 0.70 at per hour midweight.
First hour fuel burn is, second hour is for subsequent hours.
B-checks are every 800 h, C-checks every 1,600 h and D-checks every 3,200 h and there are yearly maintenance checks.
The landing gear is overhauled every 12 years.
Its Honeywell TFE731-5BR have 2,100 h and 4,200 h inspection intervals, extendable to 2,500 h / 5,000 h with optional service bulletins, and MSP per engine.
Able to fly nine passengers over 2,400 nmi, 475 Hawker 800XP have been sold for $10–13.5 million between 1995 and 2005. By July 2018, 467 were still in service, valued $1.4–2.4 million.

Civil operators

The aircraft is operated by private individuals, companies and executive charter operators, and in fractional ownership programs.
