Abstract
A method of predicting performance characteristics of an aircraft including modeling thrust-minus-drag of an aircraft with at least one mathematical model using aircraft specific data and input parameters which define the performance characteristics. Coefficients of the at least one mathematical model are learned over at least one flight. The performance characteristics are predicted as a function of the learned coefficients representative of a combined and non-independent thrust-minus-drag relationship.
