The middle column of the engine indication and crew alerting (EICAS) display contains what information?

The middle column of the engine indication and crew alerting system (EICAS) display is designed to provide critical engine performance parameters to the pilot. This column includes Torque, Interstage Turbine Temperature (ITT), and Gas Generator Speed (N1), which are all vital for monitoring the engine's operating condition.

Torque is displayed to indicate the amount of power being produced by the engine, giving the pilot insight into how efficiently the engine is operating in relation to its maximum capabilities. It helps in assessing performance during different phases of flight, especially during climb and takeoff.

Interstage Turbine Temperature (ITT) is crucial for ensuring that the engine is not exceeding safe operating temperatures, which could lead to overheating and potential engine damage. Monitoring ITT allows the pilot to make operational adjustments if necessary.

Gas Generator Speed (N1) offers information on the rotational speed of the engine's compressor section. This value is essential for understanding engine performance and efficiency and allows the crew to make decisions regarding engine settings and performance.

Since the middle column of the EICAS displays all these three essential parameters, identifying the answer as "All the above" accurately reflects its comprehensive nature in supporting the pilot with vital engine status information.
