Do-not-exceed APU EGT value under any operating condition is which temperature?

Explanation:
The limit being tested is the APU’s do-not-exceed exhaust gas temperature. EGT measures how hot the turbine section is, and it’s a hard cap—the APU’s fuel control will not allow the temperature to go beyond this point. Exceeding the limit of 1038°C can overheat and damage turbine blades and related components, so pilots monitor and keep the EGT at or below this value under all conditions. Therefore, 1038°C is the correct do-not-exceed temperature for the APU EGT. The other numbers do not represent the APU EGT DNE limit and may correspond to different parameters or systems.
