BAE Systems software has been selected for an upgrade of the Boeing C-17 transport's flight control system. The CsLEOS real-time operating system developed by BAE's US arm will be used in the redesigned automatic flight control system (RAFCS) to be installed from the 121st C-17, due for delivery in mid-2004. The RAFCS will replace the C-17's BAE-supplied automatic flight control system panel, to reduce weight and power consumption, improve reliability and overcome component obsolesence. CsLEOS is also used in the flight control system of Northrop Grumman's X-47A unmanned combat air vehicle technology demonstrator, expected to fly later this year (Flight International, 27 August-2 September).
