Which pilot control allows for lateral control of the TH-73A?

• A. The rudders
• B. The ailerons
• C. The elevator
• D. The throttle

Answer: (B)

The lateral control of the TH-73A is accomplished primarily through the ailerons. Ailerons are hinged surfaces located on the wings that function to control the roll of the aircraft. When the pilot moves the control stick laterally, one aileron moves up while the other moves down, causing the aircraft to roll towards the direction of the raised aileron. This rolling motion is essential for executing turns and maintaining level flight, particularly in coordinated flight operations.

While the rudders contribute to lateral control by assisting with yaw and helping in coordinated turns, they do not directly control roll, which is the primary function of the ailerons. The elevator controls pitch, affecting climbing or descending, while the throttle manages engine power, influencing speed but not lateral movement. Thus, the ailerons are specifically responsible for lateral control in the TH-73A aircraft.
