A matched array technology system and method for displaying in a two-dimensional array the structured interaction between different parameters of an aircraft flight. Specific applications effectively support improved flight safety and greater fuel efficiency. Proxy values of flight metrics are defined and scaled so the axes of the array contain corresponding indicators resulting in a matched array and an embedded, unique alignment vector showing the relationships between different flight variables. The flight alignment system may be used with flight data that contain discontinuities and nonlinear reversions. Wherever values intersect, flight alignment system indicators can depict proximity to the alignment vector, as well as the direction and extent of adjustments to either or both selected flight metrics to achieve and maintain controlled flight.
