True or False: The rotor brake system consists of a two position control lever.

• A. True
• B. False

Answer: (A)

The statement is true because the rotor brake system of the TH-73A helicopter utilizes a two-position control lever to engage and disengage the rotor brake. This system is designed to enhance the safety of ground operations by allowing the pilot to quickly secure the rotor blades in a stationary position when the helicopter is on the ground.

In the engaged position, the rotor brake applies pressure to the rotor system, preventing it from spinning. Conversely, when the lever is in the disengaged position, the brake is released, enabling the rotors to spin freely during engine operation and takeoff. This straightforward mechanism helps ensure that the rotor brake is easy to operate while providing reliable performance during ground handling tasks.
