TGT limiting will not be provided during which of the following conditions?

TGT limiting will not be provided during which of the following conditions?

• A. DEC/EDECU Lockout
• B. Normal Operation
• C. High Altitude Cruise
• D. Low Power Setting

Answer: (A)

TGT limiting is an electronic protection function that trims fuel to keep turbine temperature from exceeding safe limits. In normal operation, the engine control unit actively monitors TGT and enforces this limit. Even during high altitude cruise or low power settings, the system still provides this protection as the engine operates within safe temperature ranges. When the DEC/EDECU is locked out, that electronic limiting capability is unavailable, so TGT limiting is not provided. Thus, the condition where TGT limiting will not be provided is DEC/EDECU Lockout.
