1. Height knob: used to adjust the flying height of the aircraft. Turn the knob to raise or lower the plane to the required height. When adjusting the altitude, the pilot needs to pay attention to the speed and attitude of the aircraft to ensure safety.

2. Climb/descend button: used to control the climb and descent of the aircraft. Press the climb button to raise the plane, and press the drop button to lower the plane. When pressing the button, the pilot needs to pay attention to the speed and attitude of the plane to ensure safety.

3. Altitude maintenance button: used to maintain the current altitude of the aircraft. After the altitude maintenance button is pressed, the aircraft will automatically adjust its attitude and thrust to maintain its current altitude. This function is usually used during the cruise phase.

4. Vertical speed knob: used to adjust the vertical speed of the aircraft. Turning the knob can make the plane rise or fall to the required speed. When adjusting the vertical speed, the pilot needs to pay attention to the altitude and attitude of the aircraft to ensure safety.

5. Horizontal hold button: used to keep the current horizontal posture of the aircraft. After pressing the level hold button, the aircraft will automatically adjust its attitude and thrust to maintain its current level attitude. This function is usually used during the cruise phase.

6. Vertical speed selection knob: used to select the required vertical speed. Turning the knob can make the plane rise or fall to the required speed. When choosing vertical speed, pilots need to pay attention to the altitude and attitude of the aircraft to ensure safety.

7. Height selection knob: used to select the required flying height. Turn the knob to raise or lower the plane to the required height. When choosing the flying altitude, pilots need to pay attention to the speed and attitude of the aircraft to ensure safety. When using the vertical control area, pilots need to read the operation manual of the aircraft carefully and receive relevant training and certification to ensure the correct use of the vertical control area. In addition, pilots need to monitor the state of the aircraft at all times in order to adjust the flight attitude and speed in time to ensure safety.
