The Hawker 800 won its Supplemental Type Certificate (STC) in 1994. It is essentially a Hawker 700 with Honeywell’s up-rated TFE 731-5R engines replacing the earlier TFE 731-3 engines. With the -3 engines the Hawker 700 was a sluggish performer on hot days and high altitudes. With the -5 engines and the additional 600 pounds of thrust, the performance deficiencies were corrected and an additional 430 nautical miles was added to the range. The company produced 307 Hawker 800s.
In 1995, Raytheon introduced the XP version of the Hawker 800. The TFE 731-5BR engines produce 360 pounds of additional thrust, significantly improving balanced field length and adding an additional 80 nautical miles of range. The 800XP also features the Collins Pro Line 21 avionics suite.
The Hawker 800XPi was introduced in 2005. This model features an upgrade to the Collins Pro Line 21 avionics suite, a new interior, and cabin management system.
The Hawker 850XP was introduced at the 2005 NBAA convention in Orlando, FL. The 850XP comes equipped with Raytheon Aircraft designed winglets. The winglets were sized to provide distinct performance improvements while not impacting airframe inspection schedules. The range of the Hawker 850XP also increaed by 100 nautical miles. Other performance improvements include up to an 8 percent improvement in time-to-climb plus faster air and block speeds.
Deliveries of this model started in 2005.
