How can the pilot manage engine power during descent in the Pilatus PC-12 NG?

Managing engine power during a descent in the Pilatus PC-12 NG involves the use of power levers to adjust both propeller and thrust settings effectively. This method allows the pilot to control the aircraft's rate of descent and maintain an appropriate airspeed, which is crucial for safe and stable flight.

In the context of the Pilatus PC-12 NG, adjusting the power levers influences the engine output, allowing the pilot to decrease power as needed when initiating a descent. This adjustment helps to descend efficiently while managing airspeed and maintaining control of the aircraft's configuration.

Other methods mentioned, such as setting the autopilot to maintain speed, adjusting the trim, or increasing thrust to maximum, do not directly provide the same degree of control over engine power output during descent. Autopilot may assist in maintaining speed, but it does not allow for the fine-tuning of engine power, which is critical for managing descent profiles. Adjusting trim affects pitch control but does not directly modify engine power. Lastly, increasing thrust to maximum is counterproductive when descending, as it would result in an undesirable climb instead of a controlled descent. Thus, using the power levers is the most effective method for managing descent in the PC-12 NG.
