Which statement best describes the green EGT indication?

• A. 0C to 806C
• B. 807C to 1038C
• C. 692C to 1038C
• D. 0C to 100C

Answer: (A)

The green EGT indication represents the normal operating range for exhaust gas temperature. On the CRJ-550, the green arc spans from 0°C up to 806°C, showing you that the engine is within safe and efficient limits. Keeping EGT in this band means you’re not over-stressing the turbine or fuel-air mixture. If EGT climbs beyond 806°C, you move into the caution region, and near the redline around 1038°C you’d be seeing an over-limit condition that requires corrective action. The other ranges describe temperatures outside the normal operating band—for example, 807–1038°C sits in the warning area, while very low values like 0–100°C aren’t representative of typical EGT during operation.
