The statement regarding EGT gauges registering sudden changes in combustion temperature more quickly than CHT gauges is considered correct due to the different operational principles and response times of these gauges. EGT, or Exhaust Gas Temperature, gauges are designed to measure the temperature of the gases exiting the engine after combustion. This measurement is closely tied to the immediate conditions of the combustion process, allowing the EGT gauge to react more swiftly to changes in engine performance or combustion efficiency.

In contrast, CHT, or Cylinder Head Temperature, gauges monitor the temperature of the cylinder heads, which can take longer to respond to fluctuations in engine output or performance. The thermal mass of the cylinder head is greater compared to the exhaust gases, leading to a slower response time for the CHT measurements. Therefore, while both gauges are critical for monitoring engine health—EGT for combustion efficiency and CHT for engine cooling and overheating—they operate with different sensitivities to immediate changes in operating conditions.

This distinction emphasizes the importance of EGT gauges in providing timely information about the engine's performance under varying power demand and mixture settings. In other scenarios, such as engine management and troubleshooting, EGT readings can help pilots make quick adjustments to maintain optimal engine operation.
