Methods and systems for automatically controlling aircraft takeoff rolls

A method for controlling an aircraft, comprising:

• receiving an indication of a target takeoff roll path for an aircraft;
• automatically controlling a direction of the aircraft while the aircraft is on a takeoff roll to at least approximately follow the target takeoff roll path, wherein automatically controlling a direction of the aircraft includes automatically providing an input to a rudder of the aircraft;
• receiving an indication of an engine failure;
• and
• in response to receiving the indication of engine failure, transferring the input from the rudder to a rudder trim element.

A method for controlling an aircraft, comprising:

• receiving an indication of a target takeoff roll path for an aircraft;
• automatically controlling a direction of the aircraft while the aircraft is on a takeoff roll to at least approximately follow the target takeoff roll path;
• and
• gradually reducing the automatic control of the aircraft once the aircraft exceeds a threshold condition.

A method for controlling an aircraft, comprising:

• receiving an indication of a target takeoff roll path for an aircraft;
• and
• automatically controlling a direction of the aircraft while the aircraft is on a takeoff roll to at least approximately follow the target takeoff roll path including:
• automatically controlling a lateral position of the aircraft when the aircraft travels below a threshold airspeed;
• automatically controlling a track angle of the aircraft when the aircraft travels above the threshold airspeed at less than a threshold pitch angle;
• and
• gradually reducing automatic control of the track angle when the aircraft travels above the threshold pitch angle.
