Which of the following is NOT a condition for Takeoff Configuration CAS?

The condition referred to in the question that is NOT a requirement for Takeoff Configuration CAS is related to the "Condition in flight idle." For a proper takeoff configuration, the aircraft systems must ensure that the engines are in a state that provides power necessary for takeoff. The 'flight idle' refers to the engines running at their lowest thrust setting while still being operational and ready for immediate thrust application.

During takeoff, the engines must be configured to respond effectively to throttle inputs. While the other options all pertain to specific parameters that must be met before the aircraft is deemed ready for takeoff, such as flap position, trim settings, and hydraulic pressure, the flight idle state does not indicate a non-compliance condition for takeoff configuration.

The importance of these parameters ensures that the aircraft is in the appropriate setting for a safe and efficient takeoff, reflecting the emphasis on thorough operational checks prior to flight.
