The Hawker 800 is a mid-size twin-engine corporate aircraft. It is a development of the British Aerospace BAe 125, and is currently assembled by Hawker Beechcraft.
The Hawker 800 is a derivative of the de Havilland 125. The British Aerospace Board sanctioned the programme to improve the, then current and strongly selling, BAe 125 700 series in April 1981. By May 1983 the new aircraft was ready for its first test flight.
The 800 series has a number of modifications and changes over the 700; most noticeable was the redesigned cockpit windscreen. Accompanying this are a modified rear fuselage fairing as well as a glass cockpit and uprated (from 3,700 to 4,300 lb) Garrett TFE731-5R-1H engines. British Aerospace also improved the wing by incorporating new outer wing sections. This helped to reduce drag and improve aerodynamic efficiency.
