A monitoring system must provide information about the running modes for systems using what type of propulsion?

The correct answer highlights the necessity of a monitoring system that can communicate the operational modes for propulsion systems that utilize both combustion and electric power sources. A combination of these propulsion types often presents unique operational characteristics, as each mode may behave differently depending on the load, efficiency, and environmental factors.

Monitoring systems are essential in hybrid systems, where understanding the running mode becomes crucial for optimizing performance, managing resources, and ensuring safety. These systems must track the transition between electric and combustion power, monitor fuel consumption, and evaluate power usage for efficient management.

Electric-only systems would not require monitoring of combustion modes, while purely combustion systems do not engage with electric performance metrics. Similarly, a hybrid system exclusively powered by solar energy would not necessitate monitoring capabilities related to combustion propulsion. Therefore, a monitoring system designed specifically for configurations that incorporate both combustion and electric sources is essential for effective operation in those scenarios.
