Exhaust Gas Temperature (EGT), also known as Turbine Outlet Temperature (TOT), plays a crucial role in turbine engines. It measures the temperature of the exhaust gases as they exit the turbine unit. This temperature is recorded using several thermocouples placed in the exhaust stream. Pilots can monitor this data on a flight deck gauge, which displays the temperature in either degrees Fahrenheit or degrees Celsius.
In piston engines, EGT refers to the temperature of the exhaust gases at the exhaust manifold. This measurement is important because it changes with the fuel-to-air ratio entering the cylinders. By monitoring the EGT, operators can adjust the fuel and air mixture supplied to the engine, ensuring optimal performance.
