I am having great difficulty with FS Nav and Traffic View Board observing AI helicopters landing on oil rigs. Each rig has an associated flatten at sea level and the afcad is at the pad height. If I slew to the rig using either the FS Map option or either of the two aforementioned programs, the sea and hence the rig is raised to the pad height. The flatten is in the same scenery area as the rig. Might it be better in a different area either with higher or lower priority than the rig area ?Here is a view from TVB:and here from a nearby rig:GeorgeThanks to ImageShack for (http://www.imageshack.us) for Free Image Hosting

So no-one has problems with Slew mode and hardened helipads above ground level? It must be my installation.George
