The Hawker Beechcraft 800 corporate jet series began in 1984 with the twinjet 800A, which was a development of the British Aerospace BAe 125. Using AlliedSignal TFE731-5R-1H engines, it has a range of approximately 2,415 nautical miles and a normal cruise speed of around 424 knots, and is one of the most popular jets in the range. The 800SP came next, with its only difference from the 800A being the addition of Hawker winglets.
The SP was followed, in 1995, by the 800XP model. This featured an external baggage compartment and more powerful AlliedSignal TFE731-5BR engines which improved both its range and its normal cruise speed. The 850XP was first delivered in 2006, with a range extended to 2,700 nautical miles, interior cabin redesign and an upgraded ProLine 21 avionics system in the cockpit.
