1. An aircraft vision system in an aircraft taking off on a runway, the aircraft vision system comprising:
- a sensor configured to capture an image of the runway;
a processor coupled to the navigation system and the sensor and configured to;
determine a centerline line vector of the runway from the image using dedicated feature detection algorithms;
determine a position and heading of the aircraft;
determine a runway heading from the centerline line vector based on features determined by the dedicated feature detection algorithms;
determine deviation of the aircraft heading from the runway heading; and
create an aircraft line vector representing the aircraft position and heading; and
a display coupled to the processor and configured to display the centerline line vector and the aircraft line vector, thereby providing an indication of a direction the aircraft should be turned to maintain the aircraft in the center of the runway.

Abstract
An aircraft system and method provide visual input to a pilot during takeoff roll. A runway centerline line vector is determined from a captured image, a displacement of the aircraft from the centerline line vector and an aircraft line vector are determined from the image based on the knowledge of sensor characteristics. The runway centerline line vector and the aircraft line vector are displayed to indicate a direction in which the pilot may change heading to maintain the aircraft on the runway.
