On the ground, what warning will pilots receive if the avionics area temperature is too high?

The correct answer identifies the appropriate warning system that activates when the avionics area temperature exceeds safe thresholds. When this condition occurs, pilots will receive specific alerts: the MASTER CAUTION light illuminates to draw attention to a non-critical issue that requires monitoring, while the AVIONICS Overheat message is displayed on the Warning Aural Panel (WAP). Additionally, an audible warning horn sounds to ensure that the crew is alerted to the condition promptly.

This combination of visual and auditory warnings serves to provide redundancy and ensure that pilots are fully aware of the potential overheat situation, allowing them to take appropriate measures before it affects the operation of the aircraft. By activating the MASTER CAUTION light and displaying the AVIONICS Overheat message on the WAP, the system effectively communicates the need for the crew to investigate and potentially mitigate the overheating issue.
