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… Weblowest-thrust-rated version, to 5.1 for the highest-rated model.
