Final answer:
EICAS de-clutter is a feature in glass cockpit avionics that simplifies the display by removing non-essential information, allowing pilots to focus on critical data during high-workload situations or emergencies. It enhances the visibility of important alerts and parameters.
Step-by-step explanation:
The EICAS de-clutter feature refers to a system used in the cockpit of modern aircraft, most often in the class of glass cockpit avionics. EICAS stands for Engine Indicating and Crew Alerting System, and it presents critical engine and aircraft system information to the flight crew. The de-clutter function simplifies the display by temporarily removing non-critical or non-essential information, which can help the pilots focus on the most important data, especially during high-workload situations or emergencies.
The purpose of the EICAS de-clutter mode is to enhance the visibility of critical alerts and parameters when a potential overload of information could distract the crew or obscure more important data. For example, if an engine fails or there is another critical system alert, the de-clutter mode activates and reduces the data shown on the displays, highlighting only what the crew needs to address the situation immediately. Though exact implementation may vary across aircraft, generally, less urgent warnings and advisories might be suppressed or minimized in this mode.
