How are the lift and drag components of the wing affected when you lower the flaps?

When flaps are lowered on an aircraft wing, both lift and drag are indeed affected, leading to an increase in both components.

Lowering the flaps alters the wing's camber and surface area. This change increases the lift generated by the wing at lower speeds, which is particularly advantageous during takeoff and landing phases. The increased lift allows the aircraft to maintain controlled flight at slower speeds, which is crucial for these operations.

At the same time, the alteration in the airflow and the wing's geometry also increases the drag. This increase in drag is a result of greater air resistance due to the enhanced lift characteristics. The additional drag helps to slow down the aircraft more effectively during descent and landing, allowing for a controlled approach.

In summary, lowering the flaps enhances the lift while also increasing drag, which is essential for safe and efficient flight operations at lower speeds.
