The WARNING associated with LOCKOUT states: Going to DEC/EDECU LOCKOUT to obtain additional power does not remove __ limits.

• A. Max Fuel Flow or NG
• B. Oil Pressure
• C. Rotor RPM
• D. Hydraulic Pressure

Answer: (A)

The key idea is that you can gain more power with a lockout, but you cannot bypass the engine’s hard limits. When you select the DEC/EDECU LOCKOUT, you raise the available torque by temporarily bypassing the normal torque limiter, but the engine-and-fuel system still has maximum safeguards. The maximum fuel flow and the gas generator speed (Ng) are physical limits of the engine and its fuel-control system. If more power is demanded, the DEC/EDECU will allow fuel flow to rise up to its maximum, and Ng will climb toward its limit; once those limits are reached, you cannot obtain additional power, even with lockout. That’s why the warning states that going to lockout does not remove the maximum fuel flow or Ng limits. The other parameters—oil pressure or hydraulic pressure—are governed by separate systems and protections, but the specific thing the warning emphasizes is that fuel flow and Ng remain capped.
