Hi,

just want to show flightplans via the commandline parameter. But each time I show a new one, I got to question "save changes". How can I disable that.

Could not find any setting in Options / File.

THX

Hi Hans,

this normally happens only if LNM has to adapt the cruise altitude after loading. Can happen if it is too low or violation procedure restrictions.
What command line parameter do you use and what is the flight plan?

Alex

Hi Alex,

here's the command:

"C:\Program Files\Little Navmap\littlenavmap.exe" "-d EDDH/33 WSN4G WSN N125 EEL N872 LILSI Z310 WOODY WODY4B EBBR/25L"

It's AIRAC 2406 approved by SimBrief. LNM is also on 2406!

In LNM there is no red line info about any changes. I only want to show the plan, I don't care about any heights, fuel etc., its onyl a visual presentation!

So an additional option "-o" like "overwirte existing w/o asking" would be very helpful!

Thanks for the example. You do not give a cruise altitude and speed in the route string. This is why LNM adapts the resulting flight plan and marks it changed.

Using "EDDH/33 N0250A200 WSN4G WSN N125 EEL N872 LILSI Z310 WOODY WODY4B EBBR/25L" loads without change and can be erased in LNM without question dialog. LNM takes the cruise altitude of 20000 ft ("A200" is hundreds of feet) and ignores the speed of 250 kts (N0250) in favor of the speed given in the aircraft performance. The speed and altitude format is explained here: https://www.littlenavmap.org/manuals/littlenavmap/release/latest/en/ROUTEDESCR.html#speed-and-altitude

LNM adapts the cruise to avoid the red error message. Maybe I disable all questions when loading from the command line. Would make sense.

Alex

Hi Alex,

excellent idea / tipp - thx a lot!

I will check that out, and let you know!!

Well, I could not ged rid of the message. When displaying alternate routes from SimBrief data, again he asks for saving Y/N.

EBBR/19 N0263A050 LNO7L LNO LNO6X EBLG/22L

EBBR/19 N0416F310 SPI6L SPI T180 NIVNU T847 IMCOM IMCO1A EDDF/25R

EBBR/19 N0516F310 SPI6L SPI T180 NIVNU T847 IMCOM IMCO1A EDDF/25R

I understand the necessity of correcting wrong data or highlight errors during planning phase. I changed spd / alt whatsoever ... he always wants to save 😞

But I only want to display a route. Wrong data should be simply ignored (on demand and own risk). So simply ignore wrong speed, altitude, names, etc. ...

The cruise altitude of 5000 ft is too low. LNM cannot build the elevation profile for it. Your other examples work fine.

I have to see how to handle this.

Alex

Thanks Alex!

I found the 5000 issue in the meantime. That's what SimBrief gaves me. I just read the data via the SimBrief API, and display it on your great Map. Thats my used case, just to let you know.

Have a great WE!

I don't know you exact use case but you know that LNM has a SimBrief import and export function in menu "File"?

Have a great one too!

Alex

Yes, I know that feature. But it need to run thru a menue - thats not feasible for me.

I wrote a "ChartViewer" app for my Win tablet. The layout was inspired by LH LIDO app. I use this app for showing charts, calculation, OFPs etc. One of the features is, loading the present SimBrief OFP, and show it via LNM, which acts behind my GUI panels. Screenshot below.

Thats why it is vital for me, to send commands to LNM, without any dialogs interrupting the flow.

I see and wow! Looks like quite a thing. I suppose you use the LNM web API.

Alex

No, not yet. I simply prestart LNM, move it in the background. Then, when I need it, I send our discussed commandline string. That does the trick, as long as no save dialog shows up .. 😉
