Hi, Andreas!

Makes sence to me, but I cant seem to understand how the FSBUS stepper controller can cope with the throttle levers having been manually moved between two A/T events.

When in no A/T the steppers will have to be "shut down" and the stepper controller will have no idea of the position of the levers. The steppers will move with the manual positioning but the stepper controller will not "sence" the movment. Then suddenly it gets a new setpiont upon A/T enabled, remembering the last position when A/T was disarmed.

Say the current position was 50% when A/T was disarmed. You control the throttle manually and leave it at 20% when enabling a speed mode. The MCP commands 50% throttle, but the Stepper controller thinks all is OK since it was at 50% "last time". What is should do was stepping up the levers 30%.

Or do you mean introducing a "controller" in CCC calculating setpoints to the stepper controller based on AI input and the FSUIPC offset?

What maybe could ease up things was if the stepper controller was always controlling the steppers based on the offset (both in armed and disarmed A/T) and using an eletrical operated clutch to connect the stepper motor axis to the lever when in TOGA or any other A/T mode ?

Really appreciating this discussion! I obviously have lots to learn in this field.
