    Abstract

    The Document Presents The Estimation Results Obtained From The Analysis Of Flight Test Data From LCA PV1 (S6),TD1 (SG)And TD2 (SG) With Zero And Full /Auto Slat.The Aircraft Derivatives Are Estimated Using SOEM And OEM Approach. Typical Time History Matches For Model Estimation And Model Validation Are Presented . Results Show That Pitch Damping And Aileron Control Effectiveness In Flight Are Generally Lower Than That Predicted By Wind Tunnel Database. Plots Of The Estimated Values Of CIO And C1 , With And Without Slat, Show An Increase In The Aircraft Dihedral Stability And A Decrease In Roll Damping With Slat .
