Hi,
I find the extended runway centerline graphic very useful when you are about to land on an airport but, is there a way to pop up this centerline extensions lines on airports that you are flying near by? The reason why I ask you this is because when I get inside a CTR of an airport we need to fly by or fly over, I sometimes receive authorisation from ATC to cross the QMS (runway extended centerline) but they request me to report 2 nm (or 3.... etc) before arriving at this QMS. The only way I can report that information accurately would be creating a waypoint on my route crossing that centerline and track its distance, but since it's not the destination airport I just have to imagine the centerline and report an aproximate distance.
I'm using skydemon on IOS 8.02
