Abstract	The presentation consists of three parts; Gripen, UAV’s and miscellaneous activities. The focus is on FCS activities but the briefing covers some information on other a/c activities where Saab is (yet) not doing any efforts on flight controls The current status of the JAS 39 Gripen FCS is that most of the control law design is finalized. The Wake Vortex Transient Reduction function is implemented, verified and delivered to all versions of Gripen, all customers. To handle a more aft c.g. then originally specified, due to new pylons and twin store carriers, an increased AoA feedback has been implemented and flight test verified in the dual seat version of Gripen (JAS 39D). Yet to be verified is the characteristics in the single seater (JAS 39C). With regard to FCS functionality the next software load for the Gripen FCS mainly contains a cleanup of deactivated code and unused Flight Test Functions. It also contains functionality for other systems, e.g. improvements in the synthetic AHRS function. The Saab technology demonstrator UAV’s Sharc TD and Filur has been concluded with flight tests proving full autonomous flight including TO & L for conventional and low observable configurations. Saab is now developing our first products in the area, one VTOL configuration and one fixed wing TUAV. Currently flight test is ongoing with a prototype of the VTOL a/c. Other activities at Saab include development of an AEW capability for Saab 2000 by fitting a radar on the fuselage the same way that has been done on the Saab 340. This programme is planned not to contain any FCS changes. A programme where Saab has major responsibilities is the Neuron. Saab is partly responsible for the general a/c design and is responsible for e.g. the fuel system, avionic system and the functionality for autonomy. The FCS is however developed by Dassault. The R&T activities performed recently consist of participation in two GARTEUR work groups, one aiming at developing a PIO toolbox for Matlab and one where methods for robust design and verification of control laws are explored. Two master theses has been produced the last year, one where the QFT design method for control law design where used and one developing an optimized based method for V&V.
