Which system manages the fuel flow in the ERJ-145?

The fuel management system is responsible for overseeing the control and distribution of fuel in the ERJ-145. This system ensures that fuel is delivered efficiently to the engines while monitoring fuel levels and managing fuel flow to optimize performance and efficiency.

In the context of the ERJ-145, the fuel management system plays a crucial role in balancing fuel between tanks and ensuring that the engines receive the appropriate amount of fuel based on current operational demands. It incorporates various sensors and components to accomplish this task, including monitoring fuel quantity and directing fuel based on the necessary parameters.

The throttle control system primarily handles the regulation of engine power by adjusting the fuel flow indirectly through the throttle inputs provided by the pilots. However, it does not directly manage fuel distribution.

The power distribution system focuses on the electrical distribution throughout the aircraft, ensuring that all onboard systems receive adequate power. This system is not involved in fuel management.

The engine control unit is mainly responsible for monitoring and managing engine performance parameters but does not handle the overall fuel management across the aircraft. Instead, it utilizes data from the fuel management system among other inputs to optimize engine performance.

Therefore, the correct answer regarding which system manages the fuel flow in the ERJ-145 is the fuel management system.
