Which component provides rotor system pitch control in the TH-73A?

• A. Cyclic control
• B. Collective control
• C. Tail rotor
• D. Stabilator

Answer: (A)

The component responsible for providing rotor system pitch control in the TH-73A is the cyclic control. The cyclic control allows the pilot to manipulate the pitch of the rotor blades individually as they rotate around the main rotor hub. By tilting the cyclic stick in the direction of the intended flight, the pilot can change the angle at which the rotor blades meet the oncoming airflow during their rotation, resulting in changes to the lift produced by the rotor system.

This manipulation of pitch enables the helicopter to move forward, backward, or laterally, allowing for precise control during flight operations. The cyclic control specifically adjusts the pitch of the rotor blades during their rotation to achieve the desired directional movement of the aircraft.

Other components, such as the collective control, adjust the overall pitch of all rotor blades simultaneously for altitude control rather than directional control, while the tail rotor primarily provides yaw control and the stabilator is used for pitch control of the aircraft's tail, not the rotor system specifically.
