Final answer:
When the upper ECAM display fails, it can disrupt the pilot's access to critical information during the flight. The pilots would rely on the lower ECAM display, instrument panel, and other backup systems to gather information for a safe flight.
Step-by-step explanation:
When the upper ECAM display fails, it can disrupt the pilot's access to critical information during the flight.
The Electronic Centralized Aircraft Monitor (ECAM) is a system that displays crucial flight parameters and system information to the pilots. The upper ECAM display provides information such as engine parameters, fuel status, and warnings. If this display fails, the pilot may lose access to important information needed for flight monitoring and decision-making.
In such a situation, the pilots would rely on the lower ECAM display, instrument panel, and other backup systems to gather information for a safe flight.
