How does a pilot achieve controlled descent using the elevator?

To achieve a controlled descent using the elevator, a pilot lowers the elevator, which effectively decreases the aircraft's pitch attitude and results in a negative pitch. This action allows the nose of the aircraft to point downward, thereby enabling the aircraft to descend in a controlled manner. When the elevator is lowered, it increases the angle of attack, which can lead to a descent as long as the aircraft maintains a stable airspeed.

By managing the elevator control in this way, the pilot can ensure a smooth and controlled descent while also having the capability to adjust the descent rate as needed for specific landing approaches or for other operational considerations. Maintaining the proper balance and control with the elevator is essential to safely conducting a descent while maintaining the aircraft within its operating parameters.
