I am using SkyVector to have an idea of what the airspace looks like in terms of waypoints and airways.
I was wandering if anybody knows a website that displays such information but in 3D (or 3D + time) in order to navigate through the airways and check out some information as viable flight levels or altitude constraints.
I am imaging of a website/software that allows to navigate like on google earth or cesium and see what the airspace is like (qualitatively at least).
