The cabin of the 400A is more spacious thanks to the aforementioned refinements. Carrying 7 or 8 passengers and a crew of two, the interior dimensions measure: 15.6 ft long, 4.8 ft high and 4.9 ft wide. Passengers enjoy fully berthable seats that swivel up to 180 degrees. A cabin baggage area and refreshment cabinet have been added. Newly located engine mounts and the addition of sound-dampening materials makes for a more enjoyable and quieter cabin environment.
With such strong design features, it is not surprising that the Beechjet 400A serves as the basis for the military T-1 Jayhawk tanker and transport aircrew trainer. The 400A has been continuously redesigned, and has now evolved into Raytheon’s successful Hawker 400. Despite its age, the original iteration of the 400A still remains a strong contender in its class, and is ideal for corporate or individual travel.
