Custom Terrain awareness data

Hi! I've added some custom terrain awareness data but when I go to fly the simulation flight the software reports that the data doesn't cover all the waypoints. Looks like the way points go just a little beyond the data, but not my much (just the overlap amount). The question is: Once the last terrain data point is reach will the aircraft keep going at the same elevation as the last point or will it revert to something else? I'd rather not have to purchase the points required to run this large area over again if it's not necessary. Thanks!

All of the waypoints need to be on the custom terrain surface you provide. That is a check that occurs at takeoff. It doesn't let you go off the edge. 

The terrain is set to be relative to the surface you provide. 

If you are in a pinch you could check it with your data and then compare that with what the SRTM version provides. I think as long as you are not flying super low it won't matter much. The SRTM data is actually pretty good almost everywhere.

If it really is just a small area you could do another custom datasource just for the last battery that would leave the original area. That way it would be pretty cheap to process and you could get it all done on your surface.

Bummer! It's a very large area - close to 4000 acres. Is there no way to combine multiple terrain data sets -- that way I could just add the sliver around the edge that's missing? The elevation difference is quite large about 300 metres from one end of the project to the other.

You mention comparing the SRTM data with my data but on my version the terrain data doesn't seem to show visually like that - and the options for terrain awareness are at the bottom of the user interface and not in the top options as is shown on the website... what's with that? Thanks!

You wouldn't compare it visually. Do a plot in SRTM and screenshot it. Then switch data sources and do that again. If you are flying at over 40 meters it likely doesn't matter anyway unless it is a pit mine or something.
