lucky-hendrix Posted May 29, 2022 Share Posted May 29, 2022 Hi all, I have returned to the viggen after a long pause. And I noticed something weird with the aircraft. when cruising along (M0.9-0.8) with SPAK enabled, as one should, feets off the pedals, I often will notice that the aircraft will fly with a significant sideslip (about 0.5balls) to the right or to the left. And if I do nothing it will continue to fly with this sideslip ... If i use my rudder to center the ball however, from then on the ball will stay centered, even if i remove my feets from the pedals. Also, if I have this weird sideslip I noticed that if I turn off SPAK it goes away immediately ? It feels like the SPAK is not bringing the aircraft to 0 sideslip properly. Am I doing something wrong ? has anyone else noticed this ? Link to comment Share on other sites More sharing options...
Machalot Posted May 30, 2022 Share Posted May 30, 2022 I haven't noticed that before but I'll keep an eye out. "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic. And reentry from space, well, that's like Mach a lot." Link to comment Share on other sites More sharing options...
