This PowerPC kernel is being used for the next-generation Hawk Mission Systems, with aircraft employing two open-architecture mission computers. Two units allow the aircraft’s two cockpits to operate independently, each being used for different purposes to fulfill training requirements. Instructors in the rear seat can monitor the trainees in the front or configure the system for their own requirements. The second computer also offers extensive backup capability in the event of any failure. Graphics are provided for all six cockpit display panels and a heads-up display.
