What routes circuit power to the selected station for release in an aircraft?

The correct answer is selective mode. In aircraft systems, the selective mode specifically refers to a method that allows for circuit power to be routed to a selected station, enabling the operation of various systems or equipment at that specific location. This means that the power is not distributed to all stations simultaneously but is directed only to those that have been chosen for activation, minimizing unnecessary power consumption and preventing overload of other stations.

By contrast, the other modes typically involve different operational approaches. Automatic mode usually engages systems without requiring manual input, often based on preset conditions, which can lead to multiple stations receiving power simultaneously. Manual mode allows an operator to directly control which systems are activated, but it may not efficiently direct power based on the specific needs of the aircraft. Control mode generally oversees or manages the functions of the system but does not specifically designate the routing of power.

Therefore, selective mode is the most efficient method for ensuring that power is only routed to the necessary stations on an aircraft, making it the correct choice for this question.
