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.

自航空早期以来，气压测量一直是一种简单而可靠的测高方法。然而，存在两个缺点：没有直接参考地形，以及天气引起的气压持续变化导致垂直剖面变化性增加，在当今高交通密度下限制了运力和飞行效率。因此，Green-Gear的一个目标是调查卫星导航实现的几何测高的环境潜力，通过去除过渡层来增加安全性和消除空域浪费，并支持更环保的爬升和下降操作。由于改变分离定义的安全理由已经公开，不仅可以解决载人航空与无人机的整合问题(无人机已经在当前的行动中使用几何测高)，而且Green-Gear还将研究通过减少几何测高实现的垂直分离来增加能力的潜力。最后但并非最不重要的是，该项目将调查环境驱动的航线收费的潜力，并建立向空域用户收费的新机制，以激励将对气候的影响降至最低。航线收费将奖励那些避免大量具有高气候影响的空域的人，并阻碍通过高需求部门/飞行高度的航班计划，除非它优化了整体环境效益，同时对空域用户和乘客的平均成本是中性的。由于减少了垂直间隔，增加了“更绿色”空域的容量，限制了必要的飞行计划修改，进一步促进了对该方法的接受。在Green-Gear上，这三个主题的结合不仅提高了实质性的协同效应，确保了协调一致的方法；它还允许快速识别和解决可能的互操作性问题，并同步成熟相互依赖的解决方案，缩短任何和所有解决方案的上市时间。
