8.1 Physics of the Atmosphere (level 2)
International Standard Atmosphere (ISA), application to aerodynamics.



8.2 Aerodynamics (level 2)
Airflow around a body;
Boundary layer, laminar and turbulent flow, free stream flow, relative airflow, upwash and downwash, vortices, stagnation;
The terms: camber, chord, mean aerodynamic chord, profile (parasite) drag, induced drag, centre of pressure, angle of attack, wash in and wash out, fineness ratio, wing shape and aspect ratio;
Thrust, Weight, Aerodynamic Resultant;
Generation of Lift and Drag: Angle of Attack, Lift coefficient, Drag coefficient, polar curve, stall;
Aerofoil contamination including ice, snow, frost.



8.3 Theory of Flight (level 2)
Relationship between lift, weight, thrust and drag;
Glide ratio;
Steady state flights, performance;
Theory of the turn;
Influence of load factor: stall, flight envelope and structural limitations;
Lift augmentation.



8.4 Flight Stability and Dynamics (level 2)

  11. Every time we encounter failure and disappointments in life, we run to our friends first rather than to our parents maybe because we are more confident to tell everything to them.Our parent can also be our friend, but sometimes we distance ourselves to them because of fear which should not be in our mindset.
