However, in Derated takeoff thrust, the levers should not be increased beyond the fixed decate limit, otherwise a engine failure may result in loss of directional control. From Boeing 737 FCTM (my emphasis): When an engine is flat rated it means that an engine of high horsepower rating is constrained to a lower horsepower rating. The engine output in this case will always remain the same, but when atmospheric conditions such as high temperatures and high altitude ("hot and high") reduce the power output of the engine it has more headroom before it falls below the limited maximum output. In some cases the total power output of an engine needs to be constrained because th… old potato head

WebJul 18, 2012 · Rated thrust for most turbojet/turbofan engines means flat-rated thrust - holding a constant thrust over a wide range of OAT. Over this temperature range, the air density varies quite a bit, so the rotor speed required also varies, holding the same rated thrust. Higher OAT, lower density, higher N1 for the fan.

WebDec 20, 2024 · What is flat rated temperature? The term flat rating is so called because of the flat nature of thrust versus the ambient temperature curve. The curve shows that from the lowest operating temperature possible to the specified temperature, the engine produces full thrust. Above this temperature, full thrust will not be permitted.
