Which operational risk increases when a hot gas turbine engine exceeds its maximum ITT?

💡 Explanation

Exceeding the Interturbine Temperature (ITT) accelerates turbine blade creep, a time-dependent deformation, because the mechanism involves diffusion at increased temperature which weakens alloys. Therefore, creep rupture becomes more likely, rather than any issues of stalling (B) or the fuel system(C).
