Which statement best describes the CONT position when the engine is running with the start lever in IDLE?

Explanation:
When the start lever is in idle and CONT is selected, the ignition system stays active on the chosen igniter to maintain flame stability, but the start valve remains closed because starting air is no longer needed once the engine is already running. In this mode you want a single, continuous spark to keep combustion reliable, not air being delivered for starting. So ignition to the selected igniter plus no opening of the start valve best describes the CONT position during idle operation.
