If a marker says Pass NE you have to at least hit a certain latitude to the north and a certain lontitude to the east of it. Apparently, you didn't touch upon the lontitude. Do not turn back until the marker says "Rounded" to indicate you have indeed rounded it.

The marker in the web client will show when the marker is rounded.

See attached jpeg.

I did not know that Philip, thank you for the info. when I look at the figures my turning point is 118.524 E which is almost 0.5 m east of the mark.. do you know why system does not read it as it is crossed?

I don't really know if this is how it really works and I am not sure if can explain it properly, but in my mind I approach it like this: in this case, the mark is a 90° angle from a compass course of rougly 270° going to 180°. I think the trigger for passing the mark is an imaginary line at roughly 45°, so the further to the north you are, the further east you have to go to trigger it.

Like I said, I don't know if that is true, but that's the way I think of it. In the image I posted earlier I was on dc, so I made sure I had some margin.

Good luck,
Philip

Schakel is basically right.

Let's work with an example. You are about to pass the waypoint above in the attached picture.

The angle between that waypoint and the previous one (below left) is 240°. The angle between that waypoint and the next one (below right) is 170°.

To pass the current waypoint, you have to cross the imaginary line (shown in red) that bisects these two angles.

In our example, we could calculate the bisector as follows:

Total angle between the two routes:
(360°-240°)+(170°-0°) = 290°

Bisector:
240° + 290°/2 - 360° = 240° + 145° - 360° = 25° or
170° - 290°/2 = 170° - 145° = 25°

Francois

Sinbad by Balloon 2025 - Carnarvon to Dondra


From here, our home in Bharatavarṣa is now north west of us – said Sinbad to his fellow balloonists. Perhaps we can ride the wind first further north, and then catch the winds that every year bring the rain, perhaps not. It’s 2600nm and we could be aloft awhile, so, Master el-Quarters, victuals only, no sandbags, provisioning the giant hamper. It will be not a picnic!
