Oil temperature limits for TOGA and APR are the same value.

Oil temperature limits for TOGA and APR are the same value.

• A. 163C (15 Minutes)
• B. 149C (5 Minutes)
• C. 150C (15 Minutes)
• D. 100C (10 Minutes)

Answer: (A)

High-thrust phases place a heavy thermal load on the engine oil system, so the oil temperature limit is kept the same for both TOGA and APR to ensure consistent protection during peak power. For this engine, the maximum oil temperature during either TOGA or APR is 163C, and that limit can be held for up to 15 minutes. If the oil temperature approaches this limit, reduce thrust or take action to stay within the limit. The other options don’t match the official limit for these modes, either by using a different temperature or a different duration.
