EASA Part 66 Physics: Passing Module 2
Struggling with aircraft physics? We break down the syllabus from fluid dynamics to thermodynamics to help you master the formulas for your exam.
Best quote from EASA Part 66 Physics: Passing Module 2
Physics is the operating system for the entire aircraft; if you take the time to master the 'why' in Module 2, the 'how' of aerodynamics, structures, and engines in later modules will come much more naturally.

Frequently Asked Questions
The syllabus categorizes topics by the depth of understanding required. Level 1, which applies to the nature of matter, requires basic familiarization and the ability to describe fundamental concepts. Level 2, which covers the majority of Module 2 including statics and thermodynamics, requires a deeper understanding where the student must be able to apply mathematical formulas to physical laws and perform calculations.
Bernoulli's Theorem describes the relationship between velocity and pressure in a moving fluid. As air flows over the curved top surface of a wing, its velocity increases, which causes a decrease in static pressure. The air moving underneath the wing remains at a higher pressure, and this pressure differential creates the upward force known as lift.
Every aircraft component has a natural frequency at which it vibrates. If external vibrations from the engine or airflow match this natural frequency, resonance occurs, causing the amplitude of the vibrations to grow significantly. This can lead to "flutter" in control surfaces or structural fatigue, potentially causing components to shake themselves apart or fail catastrophically.
Gyroscopic principles, specifically rigidity in space and precession, are the foundation for essential flight deck instruments. Rigidity in space allows a spinning mass to maintain its orientation, providing a stable reference for attitude indicators and directional gyros. Precession, the tendency of a spinning mass to react to a force 90 degrees later in the direction of rotation, is a key factor in how these sensors detect and display aircraft turns.
Thermodynamics governs how heat energy is managed throughout the aircraft. The Second Law of Thermodynamics explains why engines can never be 100% efficient, as some energy is always lost to entropy and heat. Additionally, the concept of volumetric expansion means that materials grow when heated; for example, a fuselage can expand by several inches during high-speed flight due to aerodynamic heating, requiring engineers to design structures that can accommodate this movement without cracking.
