What does the "E" in the FEVER memory jogger stand for?

The "E" in the FEVER memory jogger refers to "Excessive ITT" which stands for Interstage Turbine Temperature. This is a critical parameter in aircraft operation, particularly for turbine engines, as it measures the temperature between the high-pressure and low-pressure turbines. Monitoring ITT is vital during engine start, takeoff, and climb phases, as exceeding the maximum allowable temperature can lead to engine damage or failure.

Incorporating this into the FEVER mnemonic helps pilots remember to check for any excessive ITT during their operational checks, emphasizing the importance of maintaining engine health and safety protocols in flight operations. The other options do not align with the memory jogger's focus, which specifically highlights the significance of temperature management in turbine engines.
