Rudderpedal centeringand artificialfeelis providedby aprimaryfeelunit,located on the copilots rudderpedalpivot assembly. A secondaryfeelunit,locatedin theaftfuselage, ensures thatthe rudder remains centeredin theeventof acontroldisconnect.
Inthe eventof acontroljam, thepilotsand copilot’s pedals willremain operable through anti-jammechanisms, however additionalpedalforce willbe requiredto obtain rudder deflection.
Two rudderloadlimiter assemblies, installedin the vertical stabilizer, give overload(stress) protection tothe ruddercontrolsystemmechanical components. A rudderloadlimiter, installedin thePCUinput assembly, allows continued controlinput movementtothe remainingPCU’s if onePCUbecomes jammed.
