Since the early days of aviation, barometric pressure measurements have been a simple and robust method for altimetry. Two drawbacks exist though: there is no direct reference to terrain, and the constant variations in pressure caused by the weather lead to increased vertical profile variability restricting capacity and flight efficiency in today’s high traffic density. One goal of Green-GEAR thus is to investigate the environmental potential of geometric altimetry enabled by satellite navigation, increasing safety and eliminating waste of airspace by removal of the transition layer and supporting more environmentally friendly climb and descent operations. With the safety case for the change of separation definition already open, not only integration of manned aviation with drones (that are already using geometric altimetry in current operations) can be addressed but Green-GEAR will also look at the potential for increasing capacity through reduced vertical separations enabled by geometric altimetry. Last but not least the project, will investigate the potential of environmentally driven route charging, with new mechanisms for charging airspace users to incentivise minimum climate impact. Route charging will reward those who avoid volumes of airspace with a high climate impact and disincentivise flight planning through high demand sectors / flight altitudes except where it optimises environmental benefit overall, while being cost neutral to airspace users and passengers on average. Added capacity in the “greener” volumes of airspace enabled by reduced vertical separations limits necessary flight plan modifications, furthering acceptance of the approach. The combination of these three topics in Green-GEAR not only raises substantial synergies and ensures a harmonised approach; it also allows to identify and solve possible interoperability issues quickly and to mature the interdependent solutions in sync, reducing time to market for any and all of them.

自航空发展初期以来，气压测量一直是一种简单而可靠的测高方法，但存在两个缺陷：没有直接参考地形，并且天气引起的压力持续变化导致垂直剖面变化限制增加。因此，Green-GEAR 的目标之一是研究卫星导航实现的几何高度测量的环境潜力，通过去除过渡层来提高安全性并消除空域浪费，并支持更环保的爬升。和下降操作。改变间隔定义的安全案例已经开放，不仅可以解决载人航空与无人机（在当前操作中已经使用几何高度测量）的集成，而且 Green-GEAR 还将研究通过减少垂直距离来增加容量的潜力最后但并非最不重要的一点是，该项目将研究环境驱动的航线收费的潜力，通过向空域用户收费的新机制来激励最小化气候影响，航线收费将奖励那些避开高气候空域的人。影响和通过高需​​求扇区/飞行高度来抑制飞行计划，除非它可以优化整体环境效益，同时对空域用户和乘客的平均成本保持中立，通过减少垂直间隔来增加“绿色”空域的容量，限制了必要的飞行计划修改。 ，进一步促进 Green-GEAR 中这三个主题的结合，不仅可以产生巨大的协同作用并确保统一的方法；还可以快速识别和解决可能的互操作性问题，并使相互依赖的解决方案变得成熟。同步，缩短所有这些产品的上市时间。
