The ______ warning will illuminate on the EICAS page in the event of a loss of hydraulic pressure to either system or with a jammed rotor distributor valve on any of the main or tail flight control servos.

• A. SERVO JAM
• B. HYD LOSS
• C. PUMP WARNING
• D. FLIGHT CTRL JAM

Answer: (A)

SERVO JAM appears on EICAS when a flight control servo is not getting hydraulic pressure or when its rotor distributor valve is jammed. In the MH-65E, the main and tail flight control servos rely on hydraulic pressure, and the rotor distributor valve routes that hydraulic fluid to the appropriate servo. If pressure to a servo is lost or that valve becomes jammed, the aircraft’s avionics detect a servo condition and illuminate SERVO JAM. This is the most specific warning for this kind of fault, signaling a direct issue with the servo rather than a general hydraulic system problem. Other warnings cover broader or different faults: HYD LOSS would indicate overall hydraulic pressure loss, PUMP WARNING points to pump issues, and FLIGHT CTRL JAM would imply a mechanical jam somewhere in the flight-control path beyond the servo condition described.
