What is a significant outcome of using the Bus Tie switch in a Falcon 7X?

Using the Bus Tie switch in a Falcon 7X is primarily intended to enhance redundancy in the aircraft's power supply system. By connecting or disconnecting the electrical buses, the Bus Tie switch allows for a more reliable distribution of electrical power. This redundancy is critical in aviation, as it ensures that if one power source fails, the other can still supply electricity to essential systems.

This feature helps in maintaining essential avionics, lighting, and other electrical systems, which are vital for safe flight operations. The ability to manage the electrical system in this way is crucial, especially in complex aircraft like the Falcon 7X, where various systems depend on a stable power supply to function correctly and safely.

In contrast, the other options do not directly relate to the primary function of the Bus Tie switch. While lighting conditions, control of engine performance, and fuel management are important aspects of aircraft operations, they do not hinge on the functionality provided specifically by the Bus Tie switch.
