Final answer:
EICAS caution messages are inhibited during takeoff when the thrust levers are set to takeoff/go-around (TOGA) position to prevent distractions during a critical phase of flight.
Step-by-step explanation:
The subject of the question involves a feature of avionics within an aircraft, specifically the Engine Indication and Crew Alerting System (EICAS), which displays critical flight information, including messages about system performance and warnings. In the context of the question, certain EICAS caution messages are inhibited during takeoff to prevent distractions to the pilot during a critical phase of flight. This inhibition typically occurs when the thrust levers are set to takeoff/go-around (TOGA) position, as this signals the aircraft systems that a takeoff sequence is in progress.
