Descend at a constant airspeed to specific altitudes in straight flight and turns.

Bottom line

Power changes are made primarily by throttle movement, followed by an indicator cross-check to establish a more precise setting. During any change in attitude or airspeed, continuous application of trim is required to eliminate any control pressures that need to be applied to the control yoke. As the airplane decelerates, check the altimeter and VSI for necessary pitch changes and the bank instruments for required bank changes.
