In the context of flight mechanics, the time period of oscillation refers to the amount of time it takes for an aircraft’s oscillatory motion to complete one full cycle. Oscillation in flight mechanics can refer to various types of motions, such as vibrations, pitch, roll, or yaw oscillations. These motions are usually repetitive and can occur due to a variety of factors, including aerodynamic forces, control inputs, or external disturbances.
ω” (omega) is the angular frequency of oscillation, measured in radians per unit time.
