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
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 900XP is a mid-size jet that utilizes the Hawker 800-series cabin. The 900XP also has enhanced winglets and new Honeywell TFE 731-50R engines with improved performance at high altitude and hot climate.
The Hawker 900XP was introduced at the 2006 NBAA convention in Orlando, FL.
