Flaps are typically used during takeoff and landing to enhance the aircraft's performance in these critical phases of flight. When deployed, flaps increase lift and drag, which allows the aircraft to fly at lower speeds without stalling. This is particularly beneficial during takeoff when the aircraft needs to become airborne at lower speeds and requires additional lift to overcome its weight. During landing, the extended flaps help reduce the landing speed, thereby allowing for a steeper descent while maintaining control and stability, as well as reducing the required runway length for landing.

In contrast, using flaps during high-speed cruise is not appropriate, as they increase drag, which can significantly reduce fuel efficiency and speed. Similarly, while performing aerobatics, pilots do not use flaps because the maneuverability and performance characteristics of the aircraft must be optimized, and flaps would complicate control inputs and aircraft behavior. While descending, although some pilots may choose to use flaps to increase lift and drag, it is not typical or necessary outside of the approach for landing; the primary flaps usage is indeed during the takeoff and landing phases.
