Final answer:
It is true that during takeoff and landing, certain EICAS caution messages are inhibited to prevent distracting the crew during these critical phases of flight.
Step-by-step explanation:
The statement is true. During takeoff and landing, certain Engine Indicating and Crew Alerting System (EICAS) caution messages are inhibited. This is a standard feature in modern aircraft design to ensure that the crew can concentrate on critical tasks during these high-workload phases of flight. The EICAS system is designed to temporarily inhibit less critical warnings that might distract the pilots during the crucial stages of takeoff and landing. Once the aircraft reaches a safer phase of flight, these inhibited caution messages will then be displayed to ensure that the crew is aware of all potential issues.
