Which system includes the Variable Rotor Speed Torque Matching System (VARTOMS)?

Which system includes the Variable Rotor Speed Torque Matching System (VARTOMS)?

• A. Accessory Gearbox
• B. Transmission Shaft
• C. N1 Gear Train
• D. VARTOMS

Answer: (D)

This item tests recognizing that a system is identified by its own name. The Variable Rotor Speed Torque Matching System is defined by that name, so the system that includes or provides this function is the VARTOMS itself. The other options are distinct engine components or subsystems (Accessory Gearbox, Transmission Shaft, N1 Gear Train) that may interact with the engine but do not carry the function-oriented name of the torque‑matching system. VARTOMS is the control system charged with adjusting rotor speed and torque to match operating conditions, so choosing the system named VARTOMS is the correct interpretation.
