设计了一种飞机纵向载荷因子（nx）的手动控制指挥系统，以完善现有的飞行控制指挥系统（例如侧杆正常载荷因子nz）。nxControl的目标是通过减少监测飞行参数和控制推力和空气制动器的工作量来协助飞行员进行手动飞行。对于nxControl概念来说，重要的是负载系数和飞机总能量变化之间的直接关系。本文给出了系统的概念和原型实现。nxControl系统由控制律组成，该控制律结合了飞行中发动机和空气制动器的驱动命令，纵向负载因子命令的新输入设备以及通知飞行员有关能量状态以确保态势感知的新显示元素。为了研究这一概念的可行性以及人类行为后果和认知需求，对航空公司飞行员进行了飞行模拟器研究。结果为这一概念的可行性提供了第一个证据。正如预期的那样，扫描行为的变化变得明显。对于标准飞行任务的测试场景，没有观察到对态势感知和性能的影响。然而，对于要求更高的任务，预期会有好处。此外，可以确认使用nxControl降低输入设备活动的假设效果。命名法
A command system for manual control of the longitudinal load factor (n x) of an aircraft is designed that completes existing flight control command systems (e.g. sidesticks normal load factor nz). nxControl’s aim is to assist pilots during manual flight by reducing the workload for monitoring flight parameters and the controlling of thrust and airbrakes. Important for nxControl concept is the direct relation between load factor and changes of the total aircraft energy. In the current paper a system concept and a prototype realisation are presented. The nxControl system consists of the control law that combines the actuation commands for engines and airbrakes in flight, a new input device for the longitudinal load factor command and new display elements that informs pilots about energy states to assure situation awareness. In order to investigate the feasibility of the concept as well as human performance consequences and cognitive demands, a flight simulator study with airline pilots was conducted.The results provide first evidence for the feasibility of the concept. As expected a change of scanning behaviour became apparent. For test scenarios with standard flight tasks, no impact in situation awareness and performance was observable. However, for more demanding tasks benefits are expected. Additionally, the assumed effect of a lower input device activity with the use of nxControl can be confirmed. Nomenclature
