When exporting a flight plan from P2A to X-Plane 11/12 format, the content of the P2A "Via" column is exported as column #3 in the .fms file.

This results in e.g. writing the string "Airway-Y101" there, where only the airway name ("Y101") is expected by the FMS file format. For example https://developer.x-plane.com/article/flightplan-files-v11-fms-file-format/ states
"The third column is the via/special column. It can have the following values: ADEP/ADES for departure or destination airport of the flightplan, DRCT for a direct or random route leg to the waypoint, or the name of an airway or ATS route to the waypoint."

So exporting some exemplary plan results in the following .fms file being created (excerpt):

Point is: Other apps do not cope well with the "enhanced" Via string format as currently written out by P2A.

Thanks for the report.

I'll get it fixed for the next release 0.0.25

Dave

Thanks for the quick update.
Revieving release 0.0.25:

1. The "Via" column contents now gets exported as expected. Fine!
2. The "Via" column now contains informantion for the wrong waypoint (see below). Not fine 😉

As you can see all "Via" moved up one waypoint (AKINI is no longer "DRCT" but now "Y104", the former Via for MARMOR ...). But for some reason for TIVDA onwards the Via airways are correct again.

Edited October 28, 20241 yr by snakem

I'll look into it.

Thanks for the quick report.

Dave

This should be fixed in release 0.0.25A.

It turns out it was an Import issue, but both should now be fixed.

Dave

Looks good. Really great and agile support. Thanks a lot!
