For how long can the maximum transient torque of 156% be sustained?

The maximum transient torque of 156% can be sustained for a period of 20 seconds. This limitation is crucial for maintaining the integrity of the aircraft's engines during high-demand situations, such as takeoff or sudden throttle inputs. The transient torque is designed to accommodate brief peaks in demand while protecting the engine from damage that could occur if such loads were sustained for longer durations.

Understanding this limitation is important for pilots to apply proper operating techniques and adhere to safety protocols. Exceeding this transient torque limit for extended periods can lead to engine overheating or failure, as the components are not designed to cope with such excessive stress indefinitely. Therefore, recognizing and respecting the stipulated time frame ensures both optimal performance and reliability of the aircraft’s propulsion system.
