Boeing FBW Response - 787

The 787 is the first Boeing commercial transport with maneuver demand control augmentation in all axes. Pitch, roll, and yaw pilot control inputs command pitch rate, roll rate, and side slip angle respectively. In the presence of atmospheric disturbances with the pilot controls centered the control system strives to keep pitch rate, roll rate, and sideslip angle zero. This means that the airplane response to an atmospheric disturbance will be less than for an un-augmentated configuration.

The pilot will need to make small inputs to return the airplane to the desired attitude and longer term inputs to manage attitude such that the desired trajectory is achieved. A key to reduced pilot workload is to let the system manage the initial, high frequency response to a disturbance and only make pilot inputs as needed to control attitude and trajectory long term.
