Hi Alex,

I've noticed that some waypoints for SID and STAR procedures in FSX flight plans are showing an altitude of zero, even when LNM displays a valid altitude.
I've come across this while trying to load an LNM exported flight plan correctly into PF3, which read the native FSX format.

The files below for a flight from EDDV to EGSS show what I mean - I've highlighted the specific waypoints:
You will see that the minimum height waypoint (unnamed, listed as User_WP) on the VAXE1G departure from EDDV is shown as a zero altitude user waypoint.
Also BKY15, BPK9 and another waypoint (unnamed, listed as User_WP) on the LOGA2A / ILS FF04 approach into EGSS are shown as zero altitude.

Is this the expected behaviour as it seems a little strange?

Thanks,
Martin
(Apologies for the slightly long post, but it seemed easier than uploading to a file-sharing site)

Hi Martin,

no problem with a long post. This actually the recommended method to post plans. 🙂

I suppose you export using one of the "Export Options" in menu "File". This can make sense in some cases but can also cause trouble if you don't know what you're doing.

Anyway, the missing altitude was a bug which might affect other exported flight plan formats too. Fixed now.

Alex

 

That's great, thank you Alex.
