The red EGT reading corresponds to which temperature?

The red EGT reading corresponds to which temperature?

• A. 807C
• B. 806C
• C. 1038C
• D. 0C

Answer: (A)

Exhaust Gas Temperature (EGT) is watched to protect the turbine from damage. The red mark on the EGT gauge shows the maximum allowable temperature for the engine. For this aircraft’s engines, that redline is 807°C, so a red reading corresponds to 807°C. A reading of 806°C is just below the limit, 1038°C would exceed the engine’s capability and indicate an overtemperature situation, and 0°C isn’t a plausible exhaust temperature. Therefore, the red-reading temperature is 807°C.
