Error drawing route - VNKT Kathmandu - RW02 - e.g. STAR KMTI1R


Recommended Posts

Hi!

 

On today's flght I encountered a problem where the route drawing completely disappears, when selecting a STAR to VNKT.

 

This happes for the follwing STARs: DARM1R, DLAL1R, IGRS1R, KMTI1R, MUNA1R.

The other arrival routes seem to work just fine.

 

My setup:

P3D V5.1.12

Navigraph Cycle 2103

P3D-World and Airport Navaid Update from Herve Sors (but disabling and perform da DB-rebuild made no difference 😑)

 

The Log also is showing some errors, which might help to identify the problem (attached also the support file for the client):

If you need any further information just let me know 🙂

As I Don't use Navigraph, I can only veryify with NavDataPro (LIDO Data) and this one is performing properly. We need to have a look into Jeppesen Data which might contain a different setup. See example below using KIMT1R STAR, RNAV/RNP02 via RATAN:

Thanks Oskar for your investigation and sorry I'm coming back to this so late 😕

 

I just did an update of my nav-database to the latest cycle 2104 and unfortunately the problem persists.

 

The only entry in the log files is also the same as before:

2021-05-01 13:16:14.096   Error   : Ungültiger Parameter.     bei System.Drawing.Drawing2D.GraphicsPath.AddArc(Single x, Single y, Single width, Single height, Single startAngle, Single sweepAngle)   bei System.Drawing.Drawing2D.GraphicsPath.AddArc(RectangleF rect, Single startAngle, Single sweepAngle)   bei i.i.r.n.r2.j(ix A_0)   bei i.i.r.n.r2.i(i8 A_0)   bei i.i.r.n.r2.i33(Graphics A_0, n A_1)   bei i.i.r.o.j.k.i(Object A_0, PaintEventArgs A_1) ... (repeated)

 

What is interesting is, that the affected STARs are on the same approach chart(s), so something has to be wrong/different with this Navigraph data 🧐

Jeppesen 10-2: DARM1R, DLAL1R, IGRS1R

Jeppesen 10-2A: KMTI1R, MUNA1R

 

The other two charts/approaches are working:

Jeppesen 10-2B: BIDUR, NAYAK

Jeppesen 10-2C: ROME2R, ROMEO, SMR, SMRA2R

 

Would be great if you could check the Navigraph data in this case. I could also open a topic in their forum if you think that makes sense.

 

Cheers

In the meantime we got a reply from Navigraph according to our inquiry related to this topic. The issue is caused due to missing data in the Jeppesen source. Navigraph will try to fix it but it cannot be promised.

Hi Urs,

 

thanks for coming back to this issue.

Hopefully this could be solved, but since this was the first time I had such a problem it's not a big deal 😉

Maybe I should switch to NavDataPro (LIDO Data) next time 😇

 

Have a nice weekend!

 

Marc
