Which of the following is NOT a maximum ITT limit for the King Air 350?

The maximum ITT (Interstage Turbine Temperature) limits for the King Air 350 are critical for ensuring the safe operation of the aircraft's engines. The limits include parameters for various phases of flight, and each phase has specific temperature constraints that must be adhered to in order to prevent engine damage or failure.

Idle ITT, Starting ITT, and Takeoff ITT are established limits that specify the maximum allowable temperatures during those specific operations. Idle ITT is relevant when the engines are at a low power setting, Starting ITT refers to the maximum temperature tolerated during the engine start process, and Takeoff ITT denotes the maximum temperature permitted during the takeoff phase when the aircraft is at full power.

On the other hand, while there are recommendations for climb performance, the specific term "Climb ITT" is not recognized as a distinct maximum limit in the same way as the other three. During the climb phase, the engines operate under condition-specific ITT limits that fall within the parameters set during the takeoff. However, there is no singular, defined “Climb ITT” limit that stands alone like the others mentioned. Understanding these limits helps ensure proper performance monitoring and adherence to operational guidelines, promoting aircraft safety and longevity.
