Final answer:
The correct answer to which caution and advisory display will not activate the 'engine left (right)' voice alert is option d. L or R OIL PR. This condition may not trigger the voiced engine alert depending on the specific aircraft and the design of its alerting system.
Step-by-step explanation:
The correct answer is option d. L or R OIL PR. In the context of aircraft caution and advisory displays, these alerts are typically associated with the parameters of the aircraft's engine. The alerts for L or R OVRSPD, L or R EGT HIGH, and L or R BOOST LO all relate to conditions that directly affect engine performance and are thus typically paired with an audible voice alert ("engine left (right)") to draw immediate attention from the pilot. However, a low oil pressure condition, indicated by L or R OIL PR, may not activate the 'engine left (right)' voice alert depending on the aircraft's alerting system design. The relationship between specific caution and advisory displays and their corresponding voice alerts can vary by aircraft make and model and the design of the alerting system.
The caution and advisory displays are part of an aircraft's engine monitoring system that provides information and alerts related to the performance and health of the engines. The 'engine left (right)' voice alert is triggered when certain conditions are met that require immediate attention. In this case, the caution and advisory display for 'EGT HIGH' is not associated with the activation of the voice alert. EGT stands for Exhaust Gas Temperature and it measures the temperature of the gases that exit the engine after the combustion process.
