The white box surrounding the digital EGT readout flashes when the EEC senses a condition that may lead to a hot start.

• A. When EEC senses a cold start
• B. When EEC is in soft alternate mode
• C. When EEC senses a condition that may lead to a hot start
• D. When the engine reaches idle

Answer: (C)

This question hinges on how the EEC uses an EGT warning to flag a hot-start risk. The white box around the digital EGT readout flashing is a visual alert that turns on when the EEC detects conditions that could lead to an excessively hot start. A hot start can damage engine components, so the system prompts the crew to pause or adjust before continuing. The indicator is specifically tied to conditions that increase the likelihood of a hot start, not to cold starts, alternate control modes, or normal idle operation. Therefore, flashing this warning means the system has identified a potential hot-start scenario and signals you to respond accordingly.
