WebThis video explains what a flat rated engine is. 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… WebA flat-rated engine's thrust remains practically constant during an increase in altitude up to a certain limit.

WebThe 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. WebMay 22, 2024 · A flat-rated engine achieves rated thrust at sea-level well below the maximum internal temperatures (ITT). Therefore, that same thrust can be achieved to a high altitude before reaching the limiting ITT ("temping out").
