Flight Mechanics

5 self-contained study topics — notes, diagrams, formulas, and worked examples for exams and GATE.

Topics

Aircraft Performance
Aircraft performance links thrust, drag, and weight to predict climb rate, ceiling, and mission capability.
Longitudinal Static Stability
Longitudinal static stability ensures a nose-up disturbance creates restoring nose-down pitching tendency.
$Neutral point x_{np}: C_{m}\alpha of whole aircraft about that point = 0$
Lateral Directional Stability
Lateral-directional stability describes coupled roll-yaw response under sideslip, rudder, and aileron disturbances.
Aircraft Equations of Motion
Aircraft equations of motion provide force-moment balance needed for simulation, trim analysis, and stability linearization.
Flight Control Surfaces
Control surfaces convert pilot or autopilot commands into aerodynamic moments for maneuvering and trim.
