ACS element text (the applicant demonstrates understanding of)

Retract flaps, if extended, after a positive rate of climb has been verified or in accordance with airplane manufacturer’s guidance.

Bottom line

After establishing the proper climb attitude and power settings, the pilot's next concern is flap retraction. Depending on the airplane’s altitude and airspeed, it is wise to retract the flaps intermittently in small increments to allow time for the airplane to accelerate progressively as they are being raised. A sudden and complete retraction of the flaps could cause a loss of lift resulting in the airplane settling into the ground.
