I’ve discovered an issue regarding the terrain indication on the Approach ATC’s “drag and vector” feature. In 1st picture below, you can see that I’m using the “drag and vector” feature to assign a heading for an aircraft. The info about the terrain, heading and distance from aircraft is displayed when using the feature. As you can see, the information about terrain is showing that there is terrain at 4,700 feet, however it’s not physically visible for the ATC or the aircraft. The second picture is the aircraft’s viewpoint, showing there are no mountains around the area. Notice that the aircraft is at 4,000 feet ASL, and around 3,000 feet AGL, therefore the aircraft should definitely see the mountain in front of it. There are a few points of “random” high elevation around this area.

I’ve been able to reproduce this bug with the following steps:
- Select PHOG as an airport to control (Approach Frequency, as Tower and Ground does not have a “drag and vector” feature).
- Use the feature to check the terrain elevation by dragging the pink line from the aircraft to the area around waypoints WUNBU, JOLUN and XUSQA. It’s quite a small area, therefore it may take a while to catch it.
- Notice how the elevation rapidly increases and decreases in this area.
My equipment is:
- iPad Pro 12,9’, using iOS 11.4
- iPhone X, using iOS 11.4
To combat the issue, I tried to clear scenery cache in case the scenery was corrupt. I’ve also pain takingly reinstalled IF, but the issue is still there.
I hope I’ve been as clear as possible and if there are any things I need to clarify or add, please state so in the replies.
