Previous owner Raytheon had made improvements in all three areas. On a "standard day", the Hawker could hold its own against its mid-size competitors.
The 900XP is the result of replacing the 850XP's TFE731-5BR engines with TFE731-50Rs. Both the -5BR and the newer -50R are rated at 4,660lb of thrust, but the -50R has a thermodynamic limit of 5,000lb, while the -5BR's is 4,660lb.
The increased temperature margin offered by the -50R allows it to maintain rated thrust as conditions degrade from standard.
At 5,000ft pressure altitude and ISA +20oC conditions, the -50R's 3,970lb of thrust is a 4.5% improvement over the 5BR's 3,800lb.
In addition to higher thrust, the -50R offers reduced thrust specific fuel consumption, the result of over 70 design and material enhancements implemented by Honeywell.
For a 1,100km (600nm) stage length, Hawker Beechcraft says there is a 4% reduction in fuel burn, and improved temperature margins have increased inspection and overhaul intervals by nearly 50%.
