What is the TOGA oil temperature limit?

• A. 163C (15 Minutes)
• B. 1006C (2 Minutes)
• C. 990C (5 Minutes)
• D. Below 120C

Answer: (A)

When using TOGA, engines are asked to deliver maximum thrust for takeoff or a go-around, which generates more heat in the oil system. To allow this high-power operation without risking oil breakdown, there is a temperature limit that is higher than normal but only for a limited time. For this engine, you’re allowed to reach and hold up to a high oil temperature for a short window—specifically, 163°C for 15 minutes. If that limit is approached or reached, you should not stay in TOGA longer than the specified duration and should transition to a lower thrust setting as needed to protect the engine’s lubrication and cooling system. This balance lets crews achieve safe high-thrust performance during critical phases while guarding against oil overheating.
