Textron Aviation subsidiary Beechcraft’s Hawker 400XPR winglet has completed testing and is now certified. Thus, the company’s Hawker winglets are now available for installation on Beechjet 400A/400XPs at Textron Aviation service centers. The lightweight winglets come with a two-year warranty and LED position lights with 5,000-hour average lifetime. By increasing wing surface area, the winglets improve low-speed handling and stability at higher flight levels. They also augment the light jet’s range by 3 to 4 percent, according to preliminary performance data.
