What are the indicators of a properly started engine on the A320?

• A. Unstable RPM during start.
• B. Stable engine parameters (N1/N2, EGT, ITT) within normal ranges, with hydromechanical and electrical monitors showing normal operation.
• C. No readings until after start.
• D. Immediate high ITT spike.

Answer: (B)

A proper start is indicated when the engine parameters come up and stay within their normal ranges, with all related systems showing healthy operation. As the starter spins the engine, N2 should rise smoothly and drive N1 in coordination, while the ITT/EGT climbs to its start range and then settles to the normal idle value. Oil pressure should rapidly come up to normal levels, confirming lubrication is established, and fuel flow should be steady as fuel is introduced and then reduced as the engine stabilizes. The hydromechanical and electrical monitors should also report normal operation—no abnormal pump pressures or generator faults—on the ECAM displays. If these readings remain within limits and remain stable, that reflects a successful start. In contrast, signs like an unstable RPM, an immediate ITT spike, or no meaningful readings until after start would indicate something is not right with the start.
