100°C

120°C

Advancing the thrust lever from shutoff to idle on the ground is a critical operation that requires consideration of the Inter-Turbine Temperature (ITT) to prevent engine damage. The maximum ITT of 120°C for this procedure ensures that the engine components are within safe thermal limits during startup. Exceeding this temperature could lead to excessive thermal stress on engine parts, which could cause malfunctions or reduce the engine's operational lifespan.

The protocol for maintaining the specified ITT limit is in place to safeguard the engine and ensure reliable performance. By adhering to this standard, operators can ensure that the engine is brought online safely without risking overheating or damage from high temperature during a ground start sequence.
