Which of the following is an aborted start condition?

• A. Engine Oil Pressure Warning Message
• B. Hung Start, No N2 increase after 5 Seconds
• C. No ITT increase after 25 Seconds
• D. Hot Start

Answer: (A)

During engine start, certain warnings and parameter trends require you to abort the start to protect the engine. An engine oil pressure warning message is a direct, safety-critical signal: if oil pressure has not come up to safe levels, the engine isn’t being lubricated properly, and continuing the start could cause severe damage or failure. Because lubrication failure is intolerable during start, the correct action is to abort the start, secure the engine, and follow the established shutdown and inspection procedures.

The other conditions describe abnormal start scenarios (such as the engine not spooling up or not showing a rise in temperature as expected, or an excessively high ITT during start). They indicate problems that may require attention, but the definitive abort signal in this context is the oil pressure warning, which demands immediate cessation of the start.
