The present invention provides a method (600), an apparatus (650), and a tiltrotor aircraft (100, 200). The method (600) comprises automatically changing (604) a position and a rotor speed of a rotor system (660) of a tiltrotor aircraft (100, 200) from a first position with respect to the roll or yaw axis of the tiltrotor aircraft and a first rotor speed in the first flight mode to a second position with respect to the roll or yaw axis of the tiltrotor aircraft and a second rotor speed in the second flight mode, wherein the rotor speed is changed from the first speed to the second speed over a time period in accordance with an acceleration-rate profile that varies over the time period using a controller (652) communicably coupled to the rotor system (660) to change the rotor system (660) from a first flight mode to a second flight mode.
