Engine power control levers are blocked from being advanced past the idle position when the rotor brake is engaged. Which statement best reflects this?

• A. They are blocked from being advanced past idle
• B. They can be advanced to full power
• C. They are locked at the maximum setting
• D. They are automatically returned to neutral when brake released

Answer: (A)

When the rotor brake is engaged, there’s an interlock that prevents the engine power control levers from moving beyond idle. This safety feature stops you from applying engine power into a rotor that’s being braked, which could load the drivetrain excessively and risk a rotor overspeed or other damage when the brake is released. So the levers are intentionally blocked from advancing past idle as long as the brake is on, ensuring you don’t couple power to a braking rotor. Once the rotor brake is released, normal control resumes and you can move the levers toward higher power as needed. This is not a situation where the levers stay at maximum or automatically snap back to neutral when the brake is released.
