Afternoon John,

Hoping you can provide some insight. I occasionally get the following error when trying to load the flightplan from FS2020 into ACARS when I push the FS Flight Plan Button in SPAACARS. Whenever this happens, it persists sometimes for a few days before I can use the FS Flight Plan button again. Am I missing a step somewhere or is there a setting that I need to change?



Thanks for your help!

Hello Eric,

I sometimes get errors with flight plan loading. In looking at the error, the first line looks like it could not figure out the file name and therefore came up with null.pln rather than filename.pln. These types of errors generally relate to control characters in the flight plan name you're trying to load that the program can't handle. Check the name of the flight plan you're loading and try to identify special characters that might be causing the issue. I think sometimes I've also had waypoints throw errors, but it usually completes enough of the flight plan that I can continue flying, unless SPAACARS shuts down due to the error. In that case I just manually enter the flight plan data into SPAACARS to activate the Start Log button so I can fly it.

In your case it looks like the name of the flight plan is the issue. If you can't figure it out, or don't wish to try renaming and reloading the flight plan in the sim, just manually enter the data into the main page of SPAACARS to activate the Start button.

Hope this helps,

John

Clarification on file name. Not control characters but special characters like an extra period '.' (other than the one used to separate the file name and extension) and other non-alphanumeric characters can cause problems. For example:

myflightplan.pln is ok, but my.flight.pln probably not ok because the program can't tell that the first period is not the filename-extension separation character (sloppy programming on my part I guess...but it's extra time to account for every possible character combination and write parsing instructions for them). I don't recall which characters I've identified that cause problems, but look at non-alphanumeric characters in the file name as a probable cause.

I have no idea John. I loaded the exact same flight with the exact same plan last night and it worked. I don't save the flightplan, just build it in FS2020 and click fly. Then when I press the "FS Flight Plan" button I get that intermittent error that sometimes lasts one flight, and sometimes lasts for days. Really weird!

That is strange. :think: I've not tried saving many flight plans with the new sim, but I would think that if it was an error with the flight plan parsing it would happen every time unless something is changed within the flight plan itself. I'll have to play around with that process and see if I can replicate the problem on my system.

I just took a look at the code to refresh my memory as to how the flight plan is handled, and the ACARS program pulls the flight plan file name and location from the sim before loading it. I'm thinking that for some reason, the memory location containing this flight plan data is intermittently empty, causing the error. I'm guessing this is likely an issue with FS2020 (couldn't be there's a bug in that sim right?) :lachen:

I'll do some further research with FSUIPC to see if they've identified this as an issue, and if not, bring it to their attention so they might look into it and possibly work with the FS2020 folks on a solution. If all else fails I can set up alternate flight plan load from file via the settings area that allows you to go directly to the saved file on your disk and load from there. Probably should have done that in the first place, but tried to keep the program like the original FSACARS program when I developed it.
