Firstly - Is there a way to have the rudder not turn during taxiing? I'm sure this doesn't happen when I see them in real life.Secondly - Why are there three separate autopilot buttons? Which sould i use? It doesn't seem to matter as long as i have one lit.James

Hi James,I do believe that in real world operations, the rudder moves slightly when the rudder is used to make small adjustments on the ground. When the tiller is used, it is my understanding that the rudder does not move.There are three separate CMD autopilots for redundency; just in case one fails. I believe that it is customary to use the appropriate CMD botton for the PF ("Pilot Flying"). This is my understanding.Tom

i believe the redundant autopilots are required for proper autolanding.you have all three active when doing an autoland in the 747 and both of them in the 737 for the same reason.>Secondly - Why are there three separate autopilot buttons?>Which sould i use?

I highly recommend the Project Tupelov IL-62 for tiller modelling. ;-)-Paul

When the ap is activated by the FO, CMD R will be activated, and when activated by the Captain, CMD L will be activated.

"When the ap is activated by the FO, CMD R will be activated, and when activated by the Captain, CMD L will be activated."It depends on company procedures. Some airlines always use the Centre.There are various reasons for doing it one way or the other.Cheers.Q.
