EAC on/off is definitely modeled. Turning EAC on is required to activate the PAC and the autopilot, so you can tell if the EAC is on by briefly turning on the autopilot. If the autopilot comes on, you can be sure the gun pipper will be stable when you fire the gun in A/G mode. :thumbup:
Still.... wouldn't it be great if ED would just animate the EAC toggle switch?
