Plain English Meaning
A descent where everything is settled and steady — speed, sink rate, nose attitude, power, and the path the airplane is flying — so the pilot only has to make small adjustments rather than fight the airplane down.
Full Definition
A descent in which airspeed, rate of descent, pitch attitude, power setting, and flightpath are held steady and within target values, with only minor corrections needed to maintain them.
Context Anchor
Used in approach and landing practice, including the power-off approach-to-stall , where the pilot first sets up a steady -like descent before raising the nose toward a stall.
