During abnormal operations, how do ECAM and QRH relate?

• A. ECAM and QRH are used independently.
• B. ECAM provides fault status and procedures; QRH provides abnormal and emergency procedures to be used alongside ECAM guidance.
• C. QRH overrides ECAM guidance.
• D. ECAM is replaced by QRH during abnormal situations.

Answer: (B)

During abnormal operations, ECAM serves as the on-board fault monitor, displaying the fault status and offering initial guidance on actions to take. The QRH contains the official abnormal and emergency procedures, which crews use alongside the ECAM guidance to work through the required steps. ECAM tells you what failed and suggests what to do first; QRH provides the detailed, step-by-step procedures to follow for that specific abnormal condition. They are complementary, not replacing one another, and are often used together to manage the situation effectively.
