Safer and more efficient airport ground movements can be planned by routing and scheduling systems based on the 4-dimensional trajectory (4DT). In order to achieve the benefits envisioned in the planning stage, an effective taxiing guidance system is indispensable. The Follow-the-Greens (FtG) guidance concept provides an augmented means for 4DT based taxiing with pilot in the loop, which is expected to guide the piloted aircraft by dynamically adjusting the lit position of green ground navigation lamps according to the assigned 4DTs. This paper presents a simulation study to investigate the feasibility of FtG based on a control theoretic modeling of the taxiing system. The 4DT conformance errors with different navigation lamp control strategies are investigated. The key performance indices, including temporal constraint violation and fuel consumption, are analysed. The results demonstrate that it is feasible to follow conflict-free 4DTs through FtG if an appropriate lamp controller is available. The results also highlight the need to proactively handle the potential conformance errors in the routing and scheduling stage.

可以通过基于4轨迹（4DT）的路由和调度系统来计划更安全，更高效的机场地面移动。为了实现计划阶段所预期的收益，有效的滑行引导系统必不可少。绿化跟随（FtG）指导概念为飞行员在回路中的基于4DT的滑行提供了一种增强的手段，该技术有望根据分配的4DT通过动态调节绿地导航灯的点亮位置来引导飞行员驾驶飞机。本文提出了基于滑行系统控制理论模型的FtG可行性研究的仿真研究。研究了具有不同导航灯控制策略的4DT一致性误差。关键绩效指标，包括时间约束违规和油耗分析。结果表明，如果有合适的灯控制器可用，则通过FtG遵循无冲突的4DT是可行的。结果还强调，需要在路由和调度阶段主动处理潜在的一致性错误。
