Where is the LDG GR CONT circuit breaker placarded located?

• A. Battery bus panel in the front cockpit only
• B. Battery bus panels in the front and rear cockpit
• C. Generator bus panels in the front and rear cockpit
• D. Generator bus panel in the front cockpit only

Answer: (A)

The idea being tested is where a specific circuit breaker is physically labeled and located on the aircraft’s electrical panels. For this airplane, the LDG GR CONT (landing gear control) circuit breaker is tied to the battery power system rather than the generator power system, and the control for landing gear is located in the front cockpit only. That means the placard showing this breaker’s location is placed on the front cockpit’s battery bus panel so the pilot can reach it easily, especially in a situation where power from the front cockpit is active or when troubleshooting.

The other panels (generator bus panels, in front or rear) are not the correct places for this particular breaker because the landing gear control is not located on those bus panels in this airplane, and there isn’t a rear-cockpit placard for this function.
