Definition of stability and control static stability and dynamic stability. Moments on an airplane. Definition of pitch angle, flight path angle and angle of attack. Criteria for longitudinal and static stability .Aerodynamic model (longitudinal mode), Longitudinal static stability and control, contribution of the wing, tail, fuselage to total moment about CG of aircraft. Equations of longitudinal static stability. Calculation of elevator angle to trim in stick fixed vsstick free longitudinal static stability, estimation of neutral point(both stick fixed and stick free), estimation of static margin, estimation of maneuvering point (both stick fixed and stick free). Directional static stability, lateral static stability, estimation of static margin, estimation of trim condition Equations of airplane motion Concept of stability and control derivatives Longitudinal and lateral directional dynamic modes Airplane response to controls Introduction to flying qualities and stability augmentation system.
