Autothrottle & autopilot relationship
The autothrottle and autopilot systems on the MD-11 are NOT independent of each other in the way that they are on Boeing aircraft. Before takeoff, pressing the AUTOFLIGHT button on the FCP arms both the autothrottle and the autopilot takeoff modes. Advancing the throttles manually past around 60% N1 will cause the autothrottle system to actually engage and begin controlling thrust. There is an audible click sound from the panel when this happens. After takeoff, press Autoflight again to do the equivalent of pressing one of the autopilot CMD buttons on a Boeing. This will actually give control of the pitch and roll modes over to the AP. From this point on, the two systems are completely unified and essentially operate as a combined system until disengagement at landing. |
