Where is the GCU located in the cockpit?

The correct understanding of the GCU's location in the cockpit is indeed that it is situated under the right side of the rear cockpit. This placement is strategic, as it allows for efficient access to critical systems and controls, minimizing interference in the main operational area of the cockpit. With the GCU, or Generator Control Unit, being essential for regulating generator performance and maintaining electrical stability, its location aids in keeping it protected while ensuring it remains accessible for monitoring and maintenance.

In cockpit design, components are typically strategically placed to optimize space and usability, which is why other areas like the left side of the rear cockpit, the center console, and the front cockpit are not suitable locations for the GCU. These choices would lead to clutter or would not provide the necessary accessibility required for managing the aircraft's electrical systems effectively.
