What is the maximum ITT for an air start?

• A. 950°C
• B. 920°C
• C. 900°C
• D. 975°C

Answer: (A)

The maximum Inter-Turbine Temperature (ITT) for an air start in the Dassault Falcon 7X is indeed 950°C. During an air start, the aircraft's engines are started using air pressure provided by an external source rather than solely relying on the aircraft's onboard systems. This method places significant thermal stress on the engine components, and strict limits are imposed to prevent potential damage. The ITT measurement is crucial because it reflects the operational temperature the engine components are exposed to during the start sequence. Maintaining the ITT at or below 950°C helps ensure that the engine operates reliably while also protecting the integrity of vital components. Exceeding this limit can lead to excessive wear or failure of engine parts, which could jeopardize safety and reliability. The other temperature options presented do not align with the engine specifications for an air start, meaning they lack the necessary technical support that the 950°C limit provides for safe operation. Therefore, the choice of 950°C is based on both safety protocols and the engineering standards set for the Falcon 7X engines.
