Final answer:
The TGT limitations for the 701D engine have changed to a specified temperature bias in Celsius. The exact value is not provided, and it's essential to refer to official sources for accurate details to ensure safe operation of the engine.
Step-by-step explanation:
The TGT (Turbine Gas Temperature) limitations for the 701D engine have changed to a specific Celsius bias, but without additional context or specifics it is impossible to state what the exact temperature bias is. It's important to refer to the engine manufacturer's manual or service bulletins for the most accurate and current information. Changes in TGT limitations affect the performance and safety of the engine, and these limitations are set to ensure the engine operates within safe thermal conditions to prevent damage or wear due to excessive temperatures. Understanding changes in TGT limitations is crucial for those involved in the maintenance, repairs, or operation of aircraft engines.
