Fsbuild-2 Flight Planner

Using 2.4.0.31 FSBuild and latest Navigraph navdata. I plug in this route from Flightaware and A588 CHI is very wrong, it brings me down to south America

This is an interesting one... if you use the NavdataPro LIDO data the route builds properly. Using the Navigraph data I get the same result that you do. There are two CHI's in W107 and in the Navigraph data the one in South America gets picked (it is first in the airway) rather than the correct one. The LIDO data looks the same but FSBuild picks the correct one. Ernie will have to look at this and tell us if the problem is in some subtly of the data or a quirk in FSB.

Sure - the other thing I noticed was this segment is redundant: ...HRB A588 ISBOP A588 CHI... although removing it and writing HRB 588 CHI doesn't help. The wrong CHI in W107 still gets chosen. Since the NavdataPro data works properly, I suspect this is a data issue.

EDIT: OK, it is a data issue - W107 is messed up in the Navigraph data; the waypoints are in the wrong order and it confuses FSBuild. As a consequence FSB selects the wrong CHI in W107 and goes zipping off to South America. When W107 is in the correct order the right CHI gets selected and we discover that CHI and SANKO are adjacent in that airway. W107 is one of those weird multi-segmented airways where the segments don't connect with each other. Some add-ons can handle that sort of thing and others don't do it very well because the data can't be presented in segments.
