Problem with some routes (wrong direction or not expanded)

Hello,

 

After searching in this forum without luck (some matches but without a solution to our problem), I would like to report a problem we are struggling with, on some routes.

 

I'll give you two examples which are poisonning controller experience

 

The first is for flights using UN615 from northern UK.

Here is the example of SWR391 from EGCC to LSZH :

UN615_KO.png

 

Euroscope simply goes direct from HON to LSZH

 

Ways I've found to recover a good route is either to disable HON (so we completly forget about UN615) :

UN616_OK_HON1.png

 

or to add LOVEL wpt on UN615. Adding an other wpt beetween HON and XAMAB won't do the trick

UN616_OK_LOVEL.png

 

The second example is for traffic coming from UK via UN859 to BCN (in Spain) VOR :

UL151_KO.png

 

Here is how it should be :

UL151_OK_PUMAL.png

 

We obtain the right route by adding "PUMAL" in the middle of UN859.

Why ES is going backward on UN859 toward BCN in UK, which is NOT on UN859 ?

 

Of course airways.txt is updated, and we have been experiencing this for ages

 

If someone could explain to us why ES is behaving this way, and if we can do something in its configuration to avoid this, it would be great

It seems ES has a problem with finding the correct VOR in the airways.txt. Because of that it simply tries to continue the route extraction or uses a wrong airway in the process. The bug if forwarded to the beta forum.

Thanks Todor.

If needed I have a simple scenario to reproduce this, as well as the configuration.

Unfortunately (or fortunately) with the latest beta they are no more reproducible. Both examples works fine with the expected route extraction. Actually there was a fix back at 01/01/2012 that changed the priority of the found fixes. Prior that the closest one were selected, but after that the one that can be connected with the given (or not specified) airway has the priority. That is surely the case at BCN. The one selected is closer to SITET than the one along UN859 at Barcelona.

Thanks for the answer Gergely. Yes indeed the BCN in UK is nearer, but not on route.

Glad to hear it is corrected, hope you will find some time to finalize this new version
