Final answer:
Auto throttles on aircraft disengage when there is significant manual adjustment to one of the power levers, indicating pilot intervention. The specific threshold for this disengagement varies by aircraft model and requires consulting the aircraft's operating manual.
Step-by-step explanation:
The question is regarding a feature of aircraft systems, specifically concerning auto throttle systems in airplanes. The auto throttles are designed to automatically control the power settings of the aircraft's engines to maintain a set speed or thrust level as determined by the flight management system (FMS) or pilot inputs. Auto throttles can disengage or "kick off" for several reasons, including but not limited to manual override by the pilot. In most aircraft systems, auto throttles will disengage when there is a significant asymmetry or mismatch in the commanded power settings.
For instance, if one power lever (often referred to as a thrust lever) is manually adjusted or moved more than a certain threshold compared to the other(s), it signals intentional pilot intervention, and the auto throttle system will typically disengage to allow manual control of the engine power. The specific threshold for auto throttle disengagement can vary among different aircraft models. Therefore, knowing the exact value for when auto throttles "kick off" when a power lever is moved involves consulting the operating manual for the specific aircraft type.
