Referred to on the charts as:

right angle to theAWY CL but

is contiguous with the base

level change of the Worthing

CTAat this position.

Affecting Qualitywings and PMDG as checked.

Hi Stephen,

what is wrong with this segment? The text you copied from the AIP is just a remark, the coordinates are exactly as published.

[srcooke 422]

Looks like FSBuild is making the entry West instead of East as per the pic.

[PeterW 23]

This is a problem in FsBuild.

The waypoint 5101N is coded in the database at a specific location between KONAN and DVR. But FsBuild ignores this coded waypoint and calculates the coordinates from the waypoint name. Which in this case produces your incorrect routing.

[srcooke 422]

From the UK AIP 5101N is not assigned a SignificantPoint Name, just a SignificantPoint Coordinates which appears to be the cause.

Shall pass the info onto Ernie.

[PeterW 23]

Yes, the AIP has only coordinates, but the systems need a name

[srcooke 422]

Peter,

Should the point not be identified as 5101E?

[PeterW 23]

The name of this point is not important. As we have seen there is no name published in the AIP, but as the data format requires a name, the data provider has to create a name. I don't know the exact rules, but for sure you should not try to read out the coordinates from the fix name. The real coordinates of the fix do not match any of the grid coordinates anyway.
