A stabilized approach, including energy management concepts.

Bottom line

If there is a deviation from the desired altitude/distance target, the energy state needs to be adjusted. There, the pilot extends the landing gear and selects landing flaps by 1,000 feet AGL, and brings the power up by 500 feet AGL to maintain the appropriate speed for a stabilized approach.
