A longitudinal stall aerodynamic modeling framework of civil aircraft based on physic-informed LSTM using flight test data is proposed. Partially high-accuracy aerodynamic parameter identified from flight test data are incorporated to compute physics-informed loss, which is fused with prediction error in loss function. The modeling framework is validated using flight test data of a civil aircraft.
