The King Air C90GTx is a further evolution of the C90GTi. Two options became standard with the C90GTx. These were the BLR Winglets and a gross weight increase to 10,485 pounds MGTOW for better full-fuel payload flexibility. With the incorporation of the BLR Winglets, this was the first time since 1984 that the basic airframe of the C90A changed in an obvious fashion.

The King Air C90GTx has great range and payload due to its features like composite winglets, swept-blade propellers and dual aft strakes. The interior features Beech's famous square-oval design which provides more headroom and shoulder space for every passenger. The cabin is equipped with 26 tuned vibration absorbers to keep the area quiet and comfortable.

In 2016 the C90GTx avionics suite was upgraded to the Rockwell Collins Pro Line Fusion. This system offers simplified single-pilot operation to reduce pilot fatigue and reduce operating economics. Pro Line Fusion includes intuitive touchscreen flight planning, high resolutions Synthetic Vision system (SVS), a Flight Management System and NextGen GPS capabilities. The SVS provides more situational awareness, and touch-interactive graphical maps provide high-resolution terrain, weather overlays, obstacles and geopolitical boundaries.
