How does ECAM differentiate warnings from cautions and what is the recommended crew response?

• A. Warnings require immediate action; cautions require timely attention; follow ECAM actions and QRH guidance.
• B. Warnings and cautions treated the same; respond as you see fit.
• C. Cautions require immediate action; warnings require delayed action.
• D. ECAM does not differentiate; relies on pilot discretion.

Answer: (A)

ECAM uses two levels to show faults and escalate urgency: warnings (red) demand immediate crew action to prevent a dangerous condition, while cautions (amber) indicate faults that require attention but are not time-critical. The crew response is to act right away on the ECAM-provided actions for the warning, carrying them out in the sequence shown, and to refer to the QRH for any steps beyond the ECAM procedure or for related abnormal procedures. Cautions should be addressed with normal priority—monitor the affected system, perform any ECAM caution actions as indicated, and consult the QRH if the situation evolves or more action becomes necessary. This matches the standard approach of treating warnings as urgent and following ECAM actions plus QRH guidance, while treating cautions as less urgent yet still requiring proper attention.
