The left side (column) of the EICAS display contains what information?

The left side of the EICAS (Engine Indication and Crew Alerting System) display contains critical information that is essential for flight management and safety. The correct answer includes fuel quantity, Bingo fuel levels, fuel flow rates, indicated outside air temperature, current amperage draw, bus voltage, cockpit altitude, and differential pressure.

This selection reflects a comprehensive set of data that pilots need to monitor during flight. Fuel quantity and Bingo provide information about fuel levels and when it might be necessary to consider diverting to a nearby airport. Fuel flow rates help in understanding fuel consumption, while the indicated outside air temperature can affect aircraft performance and safety. Current amperage draw and bus voltage readings pertain to the electrical systems that are vital for powering onboard instruments, ensuring operations are stable. Cockpit altitude and differential pressure are also crucial for monitoring cabin pressurization and operational altitude, which are critical for maintaining safety and passenger comfort.

In contrast, the other choices do not encompass the range of information provided on the left side of the EICAS. For example, while propeller RPM, oil parameters, and hydraulic pressure are important, they mainly pertain to individual engine performance and system health rather than a more comprehensive overview of operational status available in the correct choice.
