What occurs if the auto-throttle is not engaged?

The assertion that the auto-throttle can only engage with certain autopilot conditions is correct. In the Dassault Falcon 7X, the auto-throttle system is designed to enhance both safety and efficiency during various phases of flight, particularly when the autopilot is in control. However, it does not automatically engage in all phases of flight. Instead, it requires specific operational parameters to be met, such as the activation of certain autopilot modes.

This means that if the autopilot is not engaged or when the aircraft is in manual flight control mode, the auto-throttle will remain inactive. It serves to ensure that pilots maintain a level of control over the aircraft's speed and thrust settings during critical phases of flight. Understanding this functionality is vital for effective aircraft operation, as the auto-throttle’s ability to adapt to the aircraft's current flight mode is essential for optimizing performance and ensuring safety.
