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 is equipped with 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.
