By mastering these principles, you will be equipped to make informed decisions in flight operations, whether optimizing for fuel economy, climb performance, or cruise efficiency.</p>

This advanced module explores the aerodynamic relationship between lift and drag, two opposing forces that shape an aircraft’s performance in flight.
