In the event of an out of limits torque indication, the EICAS display will warn the pilot of all of the following methods, EXCEPT ______________.

The reason the correct answer is that the EICAS (Engine Indication and Crew Alerting System) display does not utilize a flashing MASTER CAUT switchlight to indicate out of limits torque is that the MASTER CAUT switchlight is designed to signal cautionary messages, which typically involve non-immediate threats or issues that require attention but may not necessitate immediate action.

In the case of out of limits torque indications, the system prioritizes more urgent alerts. The other methods listed, such as a change in color of the torque reading, an aural tone, and a flashing MASTER WARN switchlight, are all indicative of a more serious or immediate condition requiring the pilot's attention.

The change in color serves as a visual alarm that the parameters have exceeded acceptable limits, the aural tone provides an audible warning that alerts the pilot to the anomaly, and the flashing MASTER WARN switchlight is designed for critical emergencies, demanding prompt recognition and action. Thus, the absence of a flashing MASTER CAUT switchlight for this particular situation aligns with the intended function of these warning systems, focusing on immediate threats with more pronounced alerts.
