What is the Phugoid Period & How does it work?

Phugoid oscillation is a natural mode of motion of an aircraft that involves periodic pitching up and down. This motion is characterized by its period and damping ratio, which are crucial for understanding the stability and handling qualities of the aircraft.

T = frac{2pi}{sqrt{frac{g}{L}}}
T = Phugoid period, g = acceleration due to gravity, L = wingspan of the aircraft

The damping ratio affects how quickly the oscillations decay over time. A higher damping ratio results in faster decay and less noticeable oscillations.
