The Beechcraft Hawker 400 is a mid-size business jet manufactured by Beechcraft Corporation. Developed in the early 1980s, the aircraft is powered by two Pratt & Whitney JT15D turbofan engines. The aircraft was designed to compete with other light business jets of its day such as the Cessna Citation and Learjet. The Hawker 400 has a range of around 1,700 miles, and a maximum speed of around 435 mph.

When Beechcraft first developed the Hawker 400, they wanted to create a jet that was more efficient and cost effective than the other models on the market. The design of the aircraft focused on reducing drag and increasing speed. To accomplish this, Beechcraft used a high-wing design and incorporated composite materials into the construction. This allowed for a lighter weight and an improved aerodynamic profile.

Today, the Hawker 400 is one of the most popular mid-sized business jets on the market. It is used by a variety of corporate and private customers around the world. The aircraft has a great deal of versatility and can be configured to carry a range of passengers and cargo. It also has a relatively low operating cost, making it an attractive option for many operators.

Over the years, the Hawker 400 has had a few issues with safety. Most notably, in 2006, the National Transportation Safety Board issued an investigation into a fatal accident involving a Hawker 400. The investigation revealed a number of deficiencies in the aircraft's design, including a lack of fire protection in the cabin, inadequate training for the pilots, and inadequate maintenance records. As a result of the investigation, Beechcraft implemented a number of safety improvements, including the installation of fire suppression systems and additional training for pilots.

The Hawker 400 has also been the recipient of a number of innovations and new technologies. For example, the aircraft is one of the first business jets to feature a fully integrated glass cockpit, which makes the aircraft easier to operate. The aircraft also features an advanced avionics system that allows for improved situational awareness and better communication with air traffic controllers.

The Beechcraft Hawker 400 is a great example of an efficient and cost-effective business jet. It offers a great deal of versatility, and its advanced avionics system makes it an attractive option for many operators. The aircraft has had some issues with safety in the past, but Beechcraft has responded to these concerns with a number of improvements and innovations. The Hawker 400 is a great example of a mid-sized business jet that offers a great deal of performance and value.
