Which type of drag is related to lift?

Induced drag is a consequence of generating lift in an aircraft and is particularly relevant to the relationship between lift and drag in flight.

When an aircraft generates lift through its wings, it creates a pressure difference between the upper and lower surfaces of the wings. This pressure difference results in the formation of vortices at the wingtips, which, in turn, create induced drag. Essentially, induced drag increases with an increase in the angle of attack and is significant during lower speeds when lift is needed to maintain flight. Therefore, the more lift an aircraft generates, the more induced drag it experiences.

Understanding induced drag is crucial for pilots and engineers because it helps in optimizing performance by balancing the benefits of lift against the penalties associated with drag. This balance plays an important role in aircraft design and performance, particularly in terms of fuel efficiency and endurance.
