Systems and methods providing improved flight guidance are described. In some implementations, performance data from a plurality of completed flight segments of an aircraft are recorded and used to generate and/or update a regression model between one or more input parameters and one or more output parameters. Flight profile data for a current flight segment of the aircraft is estimated using the regression model and compared to flight profile data predicted based on pre-programmed performance data. The estimated and predicted flight profile data are compared to determine if a difference between the two exceeds a predetermined amount and flight guidance for a current flight segment is generated based on the estimated flight profile data if the difference exceeds the predetermined amount.
