在当前一代电子主飞行显示器中，所有变量都按比例缩放和显示，而不考虑飞机飞行路径和速度相关变量之间的内在关系，也不考虑应如何使用推力和升降舵的控制。这使得飞行员只能依靠他的经验和技能来实现飞机速度和飞行路径的理想状态。生态能量管理主飞行显示器的目标是使各种飞行动态显示变量之间的约束和复杂关系对飞行员可见并可直接操作。在这种情况下，能量域被认为是一种标准化和可视化速度和高度目标、加速度、垂直速度和飞行路径角度之间关系的手段，并为有效使用升降舵和油门控制提供控制引导线索。通过对缩放依赖性的分析来解决这种生态主飞行显示器的可行性。在概述设计问题和所需的设计决策之后，通过示例实现以及与现有显示格式和设计建议的比较来解决实用性。最后，提供了研究建议，以评估这种显示器在改善飞行员控制性能和工作量方面的适用性和有效性。
In the current generation electronic primary flight displays, all variables are scaled and displayed without regard to the inherent relationship between airplane flight path and speed related variables, and without regard how the controls of thrust and elevator should be used. This leaves the pilot to solely rely on his experience and skills to realize the desired state of aircraft speed and flight path. The goal of the ecological energy management primary flight display, is to make constraints and complex relationships between various flight dynamics display variables visible and directly actionable to the pilot. In this context, the energy domain is identified as a means to normalize and visualize the relationships between speed and altitude targets, acceleration, vertical speed and flight path angle and to bring out control guidance cues for the efficient use of elevator and throttle control. The feasibility of such an ecological primary flight display is addressed through an analysis of the scaling dependencies. Following an overview of the design issues and required design decisions, the practicality is addressed through an example implementation and a comparison with existing display formats and design recommendations. Finally, recommendations for research are provided to assess the suitability and effectiveness of such a display in improving pilot control performance and workload.
