The Hawker 800 is a series of mid-size corporate aircraft developed from the British Aerospace BAe 25 by Hawker Beechcraft. It has a number of modifications and changes over the 700, the most noticeable being the redesigned cockpit windscreen. 

The Hawker 900XP improves on some of the best traits of the Model 850XP, including fuel efficiency, aerodynamics, and performance capabilities. Updated winglets improve hot-and-high performance, range, and take-off distance.
