The yellow arc on the ITT gauge indicates temperatures between which range?

Explanation:
Inter-Turbine Temperature (ITT) gauge color bands show operating limits for the engine. The yellow arc is a high-temperature caution range, indicating you’re near the limit but not yet in the redline. For the Beechjet 400A, that caution range runs from 680 to 700 degrees Celsius. If ITT climbs into this band, monitor closely and back off thrust to bring ITT back toward the green normal range; sustained exposure at or above the upper end moves toward redline. The other temperature ranges listed do not match this caution band.
