Oil temperature in the amber range is between which temperatures?

• A. 156-163 C
• B. 140-150 C
• C. 100-110 C
• D. 165-175 C

Answer: (A)

Oil temperature is shown with color-coded ranges, where amber marks a high, cautious operating area just before reaching a dangerous level. For this aircraft, the amber band is defined as 156 to 163 degrees Celsius. Being in this range means the oil is hot and you should monitor it closely and be prepared to take cooling or power-reduction actions if it doesn’t stabilize, before it reaches the red zone. The other options fall outside this defined caution window: temperatures lower than this range are not in amber, and temperatures above it (165–175 C) would generally be considered red/danger.
