Under what condition does EICAS automatically display parameters outside the allowable range?

Under what condition does EICAS automatically display parameters outside the allowable range?

• A. Only upon user request
• B. When any sensed parameter falls outside allowable range
• C. When engine RPM exceeds limit
• D. When outside air temperature changes

Answer: (B)

EICAS is designed to alert the crew automatically whenever a parameter goes outside its allowable range. The system continuously monitors engine and aircraft parameters and compares them to predefined limits. When any sensed value exceeds a high limit or drops below a low limit, EICAS flags that parameter and displays it so the crew can respond quickly. This automatic surfacing isn’t dependent on manual request and isn’t limited to any single parameter like RPM or outside air temperature; it occurs for any parameter that drifts outside its acceptable envelope.
