Autorouting not equal to Real-Life Routing

Hello everyone,
I have noticed that the auto-routing does not match the frequently flown routes of the real airlines or the first waypoint after the SID is selected incorrectly.

I know that it depends on the weather, but 98% of the flights to the Canary Islands (LEPA,LPFR,LPMA, GCTS…) fly via the “MODRU” SID.

I get the waypoint “COLA VOR/DME” as the first point after the SID for high airways.
Only with low airways MODRU is selected, but with a distance of more than 500 NM, low airways are not necessarily the right choice. I used Standard IFR and also Airline CAO for Auto-Routing.

I don’t know if this is also the case at other airports
Here the examples

Now with Low Airways

Hello Lukas!

We’re aware of the fact that the autorouting functionality can be improved, and will add your thoughts to the list of things to see to. Thank you for the great feedback!

Regards,
Malte

Another example

When i use Simbrief for the Route i get direct the route, which the Pilots are flying

The route calcution was done today 18/12/2020 at 1645Z

IFPS Validation of Navigraphs Calculation

Route copied from Navigraph “Type Route” to Simbrief
From EDDF to “EDDK” (Low Airways)

Up this picture i displayed High Airways

EDDF DCT TAU DCT SOGRI L608 DENUT L610 KOPUL Q60 UGNUS N14 BAKUR DCT NEBIN DCT 5420N DCT 5430N DCT 5340N DCT 5150N DCT ALLRY N358A EBONY J573 ENE DCT KJFK

It is same-day routing and weather should be equal for every routing (official Lufthansa Cargo 8160 & Simbrief and Navigraph) and AIRAC is of course actual.

Example Two

This flight starts in few minutes (1941Z)
