rated output
Definição1
Rated output means the maximum power/thrust available for takeoff at standard day conditions as approved for the engine by the ANAC, including reheat contribution where applicable, but excluding any contribution due to water injection and excluding any emergency power/thrust rating.

Nota adicional1
1.2.3.6 The current definition of “rated output” included the expression “maximum power/thrust available for take-off” and was not the correct parameter for this purpose. Firstly, the installed power/thrust was not a certificated parameter, as it included deductions from the rated thrust for installation effects, such as nacelle drag and aircraft power requirements. Secondly, where an engine was approved with additional emergency thrust capability, it was not necessary to carry out the testing at this higher thrust. In practice, the certificated (or uninstalled) rated take-off thrust has always been used for emissions certification. Also, as all engines affected by the Annex were turbo-jet or turbofan engines, the output of these engines was always measured in terms of thrust, and “thrust” should be used instead of “output” throughout the Annex. A new definition had therefore been developed.
Contexto
Thrust settings: The engine shall be tested at sufficient power settings to define the gaseous and smoke emissions of the engine so that mass emission rates and Smoke Numbers corrected to the reference ambient conditions can be determined at the following specific percentages of rated output as agreed by the certificating authority.
