What does the term "cross-control" refer to in aviation?

• A. Using opposite aileron and rudder inputs
• B. Controlling altitude with flaps
• C. Coordinating turns with throttle adjustment
• D. Maintaining speed while ascending

Answer: (A)

The term "cross-control" in aviation refers specifically to the action of using opposite aileron and rudder inputs to control an aircraft in flight. This technique often occurs during situations like a sideslip or when correcting a turn, and it is generally associated with adverse yaw, which is the tendency of an aircraft to yaw in the opposite direction to that of a turn. When pilots apply opposite inputs, it helps to maintain directional control but can also induce a loss of efficiency and may lead to an uncoordinated flight, which is unsafe. In essence, controlling an aircraft properly requires not just understanding how to use ailerons and rudder, but how to apply them together in a coordinated manner. It's crucial for pilots to recognize and avoid situations where cross-control elements are used improperly, as this could lead to scenarios like a spin if the aircraft is mishandled. The other choices relate to different aspects of flight operations that do not accurately define "cross-control." While controlling altitude with flaps, coordinating turns with throttle adjustment, and maintaining speed while ascending are all important to flying, they do not encompass the particular concept of using opposite control inputs in flight dynamics.
