What needs to be confirmed before telling the pilot to proceed with any control surface adjustments?

Before instructing the pilot to proceed with any control surface adjustments, confirming the wing position is crucial. The wing position impacts the aircraft's aerodynamics and control effectiveness. Any movements or adjustments made to the control surfaces can significantly affect how the aircraft responds, especially if the wings are not in their proper position during pre-flight checks.

Proper wing positioning is essential for ensuring that the aircraft is in an optimal state for takeoff or maneuvering. This is especially important for aircraft with movable wing components, such as flaps or leading-edge devices, which can dramatically influence the lift and handling characteristics of the aircraft during different phases of flight.

Ensuring the wing position is correct helps prevent potential issues that could arise from unforeseen configurations that might compromise safety and operational integrity. Other factors such as fuel status, weather conditions, and the maintenance log may also be important in a broader operational context, but they are not as directly tied to control surface adjustments as wing position is.
