Fly-by-wire Rudder not working after SU5, when flight is started C&D

Hi team,

Requesting prioritisation on a first-party aircraft issue. @Boris

Bug: On the C-17, rudder input is completely ignored when the aircraft is loaded Cold & Dark. Loading Ready for Takeoff on the runway works as expected.

Repro: Load C-17 → Cold & Dark → apply rudder → no deflection. Reload same flight on runway → rudder works.
See screenshot below, full deflection on the rudder pedals but no rudder deflection on the aircraft.

  • All native FBW SimVars checked (FLY BY WIRE ELAC FAILED, FLY BY WIRE ELAC SWITCH, FLY BY WIRE FAC FAILED, FLY BY WIRE FAC SWITCH, FLY BY WIRE SEC FAILED) no abnormal state.
  • Keybinds and axis assignments verified, input is registered.
  • C-17 uses the fully native FS2024 FBW system, so the failure appears to be rooted here.

Regression introduced in SU5. Unfortunately, not caught by MS QA Teams during testing. All tests performed on PC, been unable to test consoles at this time.

@FlyingRaccoon

Just found out something interesting… the issue is fixed by cycling AUTOPILOT MASTER off-on-off. After doing this, rudder works normally again.

Hi @vantech ,
Sorry for the delay,

I was able to reproduce the issue but could not find the reason for this behavior yet.
I will update you as soon as I have some news to share.

Thank you

Regards,
Boris
