Engine failiure & autotrim

[ETOPS773]

When a large aircraft with an autopilot / autothrottle (which at the time is active,ie on climbout,plane intercepting a waypoint,autothrottle keeping you at 240 kias) looses an engine,does the autopilot automatically trim the aircraft and dampen the initial swing or do the pilots have to do this manually...ie maybe following the flight director??

The 777 does using TAC.

MD-11 has a device called 'Parallel Rudder' and its operation is an engaged autopilot mode in which the flight control computer controls the rudder to counter asymetric thrust or to align the aircraft at 150ft AGL during autoland. This mode engages automatically as well when the AP is on during TO or GA, and during dual land or single land. Pilots can feel the rudder motion in the rudder pedals and the bank angle limiter on the PFD indicates 10 degrees or less.

The 747-400 has a similar system to the MD-11 during Autoland. However, during normal autoflight (climb, cruise, descent) when only one autopilot is being used, it is up to the ailerons to keep the aircraft on track. The Yaw Damper system may assist the ailerons by moving the rudders a few degrees. However, it most likely won't have enough authority to handle the asymmetry. Manual rudder trim input will probably be required when not in the (auto)landing phase.
