ACS element text (the applicant demonstrates understanding of)

Hazards associated with a no flap or nonstandard flap approach and landing, including an asymmetrical flap situation.

Bottom line

Large changes in flap deflection at one single point in the landing pattern can produce large lift changes that require significant pitch and power changes in order to maintain airspeed and descent angle. Incremental deflection of flaps on downwind, base leg, and final approach allow smaller adjustments of pitch and power and support a stabilized approach.
