I received a request to change handling of task sectors. Right now LK always navigates to the waypoint that is a base of the task sector. The better behavior would be to navigate to the closest point of a sector related to the glider. It applies to the start, waypoint and finish sector types.
The only exception I can think of are start sectors. Only line type does not have any problems and should be fixed for sure. In case of "FAI sector" it seems reasonable to navigate to the waypoint itself. Cylinder on the start is also tricky especially because of its tail part.

all right thanks

This request has been solved, at least for paragliders. Time to close it and remove the sticky?

That's a thing that really have to be done. It's a TOP request, like the start In and Start Out request.
Do you know that even the most expensive instruments for paragliding don't work well with large cylinders? The only one that work pretty well is the Flymaster B1 Nav (which I have! eheh), I only use good stuff! That's why I also use LK8000! ;)
Long floaty glides in the smoke til about 10k from the turnpoint (set to keep us from going over the back of the hills), then long sinky glides to the turnpoint. The flymaster pilots are good to know when trying to find the tangent point on a 5k cylinder, I imagine all the other instrument makers will be upgrading software to optimise routes round big cylinders now.

good old Condor Indomavel made a good job last year.. the time we use his example has come.

By the way, merely navigating to the nearest point on the cylinder may not be what we are interrested in. To make it the shortest route I would like to be directed to the point which gives the shortest path to the next waypoint.
The picture posted by Condor Indomavel in the bottom of this topic illustrates this:

Navigate shortest route , taken.

Yes, and this is of course the same thing I have requested for optimisation of paraglider tasks. Its really important for PG, since (large) cylinders are used in most tasks.
Maybe we could have a ON/OFF selection for "Navigate shortest route" in the task setup dialog? (this is the how it is done in the Nav+ software)
Regarding start cylinders, you have already solved this elegantly in PG mode.
Mat: check it out in PG mode, i think you would like it!

Normally task start are lines, not sectors, so maybe this is not an issue.
truly when you are passing a turnpoint, you should have a bearing line to the nearest point in the sector, and so for all values in the informations.
If the turnpoint is in a sector, then navigating to it will point you to the vertex.
Otherwise, if you are approaching with a wide angle, you will be pointed to the nearest line of the sector.
Is it ok?
So basically the new approach should be: always point to the nearest place to cross the sector, except on start sector (if it is..a sector of course)

Regarding start sector, I assume it should be configured in a task. There are regatta races when everyone start at the same time and in such condition the shortest path to the line is useful (it is up to the pilot to be in a good position before the start). The other case is when you have a time window, so you have time to start a task at specific point of the sector.
For the rest parts of racing tasks (waypoints and finish) I think it is always true to have the nearest point selected as navigation target. AAT tasks should be handled separately of course.

It has to be considered the fact that if you exit a start sector (task start) from any other point on the sector line, different from the vertex (waypoint) the task distance will be greater, even if by little values. If you have 3 or 4 sectors in a race, it can be as high as 4-6km which account for a big difference in task speed.
So are we sure that the bearing line should point to the closest sector entry-exit, instead of the vertex?
Just my doubts.
