On a go-around at Auckland from about 400 ft because the preceding aircraft was slow to vacate, the thrust levers were moved rapidly from idle to TOGA. During the go-around the ENG 1 EGT peaked at 906 °C and stayed between 875 °C and 890 °C for roughly 25 s before stabilising at 845 °C in the climb.
