If remote control is lost, where can control be maintained?

• A. Engine control room
• B. FADC/LOCOP
• C. HMI
• D. Bleed air system

Answer: (B)

When the remote control link is lost, you still have a direct local interface to manage the engine: the local control panel connected to the FADEC, known as the LOCOP, provides that access. The FADEC (FADC) is the engine’s digital control unit that schedules fuel and manages engine parameters, and the LOCOP lets you command it directly from near the engine. This combination keeps you in control even without the remote link, allowing you to select safe operating modes and set limits to maintain safe operation. In contrast, a distant engine control room would rely on the remote link to issue commands, so losing the link means you’d lose control from that location. The HMI is mainly a display/input surface for monitoring and basic interfacing, not a guaranteed independent control path if the remote connection is down. The bleed air system is a separate subsystem and doesn’t provide engine control authority.
