Flight Theory. You should know:
- be able to explain in detail how a wing creates lift, including the relevance of venturi tubes and Bernoulli’s theorem
- be able to define and use terms such as chord line, angle of attack, aspect ratio, centre of pressure, washout
- be able to describe the aerodynamics of the stall
- be able to simply describe factors affecting stability in pitch, roll and yaw · understand the relationship between glide ratio and l/d ratio
- understand the effect of ballast
- be able to name the forces on a glider in steady flight and explain their relationship
- be able to name the various types of drag and explain their causes
- be able to describe the relationship between the induced, parasitic and total drag and airspeed using drag curves
- understand and be able to use a polar curve
- understand the basic working principles of altimeters and variometers
- understand terms such as total energy and airmass in connection with variometers
