The engine start information displays on the ECAM engine page when the pilot initiates the engine start. Which option is correct?

• A. When the pilot initiates the engine start
• B. During engine shutdown
• C. When the APU starts
• D. When fuel is exhausted

Answer: (C)

Engine start information on the ECAM engine page appears when a pneumatic source is available to start the engine. In the A320, that source is usually provided by the APU bleed air, so the ECAM engine page shows the start data once the APU starts feeding bleed air and the engine start sequence actually begins. Until bleed air is available, you don’t get the detailed start parameters displayed, even if you’ve pressed the start pushbutton. This is why the moment the APU starts (providing the necessary bleed air) is the trigger for the engine start information to appear on ECAM. The other options don’t reflect when the start data becomes visible: the start data isn’t shown just because you pressed start, it requires the pneumatic source to be active; it isn’t related to engine shutdown or to fuel exhaustion.
