Phugoid Oscillation
Definition
A long-period oscillation of aircraft pitch and altitude at essentially constant angle of attack. The aircraft slowly exchanges altitude for airspeed and vice versa. Usually lightly damped and easily controlled.
Why Phugoid Oscillation Matters for Pilots
Understanding Phugoid Oscillation is critical for passing the FAA Private Pilot Knowledge Test and performing safely in flight. Aerodynamics questions make up a significant portion of both written exams and oral checkrides. Pilots who grasp concepts like Phugoid Oscillation can make better decisions during all phases of flight, from takeoff to landing.
Exam Tip
This concept is commonly tested in aerodynamics-related questions on FAA and EASA exams. Make sure you can explain Phugoid Oscillation in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
