Flight Planner using DCT

Charts General
1

Hi all,

I’m quite new to Navigraph, but I have a question on the flight planner. If I enter a departure and destination airport, the autoroute shows a DCT route instead of flying via appropriate waypoints. Is there a setting I need to change? Happens e.g. with EDDF - EHAM.

Thx for any assistance!

Hi,

For this very short route, there is no ideal airway to take. If you look at the enroute chart, there are very few airways available for this routing and many of them go in the opposite direction. Hence our planner selected a DCT here. You can of course change it by manually adding waypoints to your route. If you plan a longer route, or where there are more airways available, you will see that it selects appropriate airways.

Regards,

Stephen

OK, thx! I was wondering because Simbrief does generate a route.

Interesting. Well, we use different algorithms.

What is the route you are getting there?

Stephen

E.g. EHAM - EDDF:

Navigraph: EHAM EDUPO Z739 AMOSU DCT UNOKO EDDF
Simbrief: EHAM EDUPO Z739 MISGO DIXAT T149 LIPMI T911 ROLIS EDDF

Or EDDF-EHRD (a better example):
Navigraph: EDDF TAU DCT INKET EHRD
Simbrief: EDDF SOBRA Y180 BITBU Y181 DEMUL M624 NIK EHRD

SimBrief’s route is a Low airway route. As you can see on our charts, the T911 airway is Low only (max FL245). If you use Autoroute in Navigraph Charts using the Low airways option you will get:

EHAM EDUPO Z739 MISGO T911 ROLIS EDDF

I’m investigating the second example.

We have now made some changes to our route calculator, which will improve mainly shorter routings like this one, which to a higher degrees will use airways when they exist also for short hops. If you try now, you’ll see this end result:

With the final route being EDDF OBOKA Z28 DIBIR T601 OKIDU DCT INKET EHRD.

Please have a look and let us know what you think.

Kind regards,

Stephen

Hi, that looks much better. Not an expert on routes, but at least it is following airways now.

Thanks for so quickly looking into this!

I’m quite new to Navigraph, but I have a question about the flight planner. I have the same Problems by calculating a route, eg LSZH to EDDK. The autoroute shows only a DCT route instead of flying via appropriate waypoints. I can’t see any change after your improvement what they point to.
These DCT connections mostly occur in Germany. Will there be an improvement soon?

Hi,

Please check it again now. We had forgotten to clear a cache with the previously sub-optimal DCT routes. Now LSZH-EDDK results in: LSZH DCT ZUE T163 KOVAN L608 RIDSU T881 ROLIS DCT GULKO DCT EDDK

Dear Stephen,
it works very well now! For other routes into Germany or to Netherland too!
Thank you for developing.

Unfortunately there was no info to my mailaddress about your message. What else do I have to set, except “Watching”.
