Operational Context
Hawker 800 — midsize twin-engine business jet
The Hawker 800 first flew in 1983 and entered service in 1984. It evolved from earlier BAe 125 models with aerodynamic refinements and updated systems. The aircraft features a low-mounted swept wing and twin rear-mounted turbofan engines.
Powered by two Honeywell TFE731 turbofan engines producing approximately 4,300 pounds of thrust (19.1 kN) each, the Hawker 800 cruises at around 450 knots (833 km/h). Maximum takeoff weight exceeds 28,000 pounds (12,701 kg). The cabin typically seats eight to nine passengers.
The Hawker 800 achieved strong sales in the midsize jet market. Numerous upgraded variants followed, extending the platform’s lifespan. The model remains a common sight in business aviation fleets.
