Engine derate. The reason for engine derating is to prolong its operating lifetime. It appears to be a de-rated take-off to achieve the minimum screen height on departure. Also the severity of the derate may vary in relation to the severity of the event.

The level of derate can be changed by the operator. Cummins emergency rated engines are specially designed to not shutdown or derate due to DPF loading. However engine deteriorating aka derating can be extremely beneficial in certain situations.

The driver display says 25 torque derate in 3 hours. 1500 1460-1470 1800 1750-1800 1900 2100 2350 2600 2800 3000 2960-3000 1500 1460-1470 1800 1750-1800 1900 2000 2100 2200 2300 2350 2400 2500 2600 2800 3000 2960-3000 3300 3600.

Engine deteriorating aka derating as the name suggests is the process of reducing the engine thrust lower than the maximum rated thrust for a particular take off. A derated thrust takeoff is a takeoff that is accomplished utilising less thrust than the engines are capable of producing thrust rating under the existing conditions of temperature and pressure altitude. Derating is beneficial as it enables a prolonged engine lifeespecially for hot sectioncombustion chamber turbines.

It has not actually derated. Derating sometimes is done intentionally when you want to prolong the engines life and avoid substantial wear or damage. Engine derating is the modification of an engine to operate at a lower output than its normal capability.

This video talks in detail about what an Engine Derate is and what the history of them is. After derating often it is possible to reduce thrust further using assumed temperature or another approved method of reducing thrust if less thrust will cover your planned TOW.
