PMDG winds export issues.

[Raimo]

Hello,

PMDG wind export is having formatting errors with full degree lat/lon waypoints.

For example, .wx file is generated with a waypoint name 69N060W, but it should be 6960N instead. At its current state, those improperly formatted waypoint names will be disregarded by FMC and wind data for particular waypoint will remain blank or get deleted. Half degree waypoints like 5530N09000W work normally.

Also, specifying a PMDG export path only exports wind data file into that single path and no other even though settings page states that other PMDG aircraft paths are also detected.

The exporting was in spec and working previously. Is there some kind of specific new spec we should be following other than this observation regarding trimming leading zeroes with "whole degree" waypoints? We are not aware of any spec change but if there is something we can follow it would be appreciated.

And which folder(s) are not being seen? Can you please open a ticket with specifics here so we can analyze? Thank you.

Hi Damian,

Thank you for the reply. I will open the ticket as requested.

Hi @damian

Any chance for a hotfix?

This is affecting fuel predictions on long-haul sectors. Unfortunately, PMDG changed the spec without publishing it.

**1. Whole-degree lat/lon waypoints use the wrong name format**
The .wx export writes whole-degree waypoints as `69N060W`, but the PMDG FMC expects the ARINC 424 short form `6960N`. Because the names don't match, the FMC ignores those waypoints, and their wind data stays blank or gets deleted. Half-degree waypoints such as `5530N09000W` work normally.

Example from an LIRF–KEWR export:
`47N015W` → should be `4715N`
`46N020W` → `4620N`
`40N060W` → `4060N`

Expected mapping:
- N + W: `4715N` (longitude 100 or more: `50N140W` → `50N40`)
- N + E: `4715E`
- S + E: `3520S`
- S + W: `3520W`

As a stopgap I am currently post-processing the exported .wx files with a small background .exe to rename the LAT/LON waypoints and update the .wx file anytime ASFS generates/refreshes it.

A proper fix in AS would be much appreciated.

Thanks!
