Hi there,
A couple of months ago, I started noticing (as a controller) that almost all aircraft from EIDW-EHAM were using a route via REDFA, rather than ending at LAMSO. This is counter to what pretty much every real world aircraft flies, and years and years of there being no issues with this traffic flow.
Although the top 4 routes are indeed valid and will pass validation by Eurocontrol, they are all 444 NM (+ 9.6 %) compared to the perfectly valid shorter route of 407 NM (+ 0.5%).
A quick search of the Real World Flightplan Database will also show that the shorter route is the one used in real life.
As such, would it be possible to make this route the preferred, and remove the route via REDFA?

Thank you!
