Radio Navigation (old style)

[bagolu]

I would like to use LNM with radio navigation : The 1944 station list is available as a CSV file.
It includes the location, a radio frequency (kHz) and 4 beam directions.

Navigating with theses beams is done listening to audio transmission of morse code (A & N)
A simulator addon exists : https://flightsim.to/file/21201/radio-range-navigation

What's missing with LNM is a representation of the beam direction like ILS (Beam and N side)

Does anyone thinks this could be done in a way or another ?

It could be done by extending the CSV file format with a bearing number.
Do you have an example or link for such CSV file?

In the radio range navigation mod there are 2 csv :

One specific for LNM. Basic format (without beam directions) :
TACAN AP 379 32.475 -99.6833 0
TACAN AK 371 35.05 -107.6689 0
TACAN AF 317 37.0775 -89.9217 0

And one with the directions :
2 371 Acomita LFR AK 35.05 -107.6689 A 87 177 267 357
3 317 Advance LFR AF 37.0775 -89.9217 A 81 181 261 342
4 368 Akron Colorado LFR RN 40.1625 -103.1878 A 78 168 258 348

Columns from this one are :
id,freq,name,morse code,lat,long,A or N type,dir1,dir2,dir3,dir4

But how would they be represented in LNM ?
I haven't found any userpoint with such capability

It seems someone managed to do something. Icons seem to be userpoints but I don't know how he made the beams

No idea. You have a source or link?

[bagolu]

unfortunately no... only this screenshot

userpoints are super fine especially for this kind of oldies flight planning

Noted in issue #1031.

Ok, I have the fine word on this : beams are made with user airspaces !

[albar965]

Ok. Thanks for the confirmation. I can only add the userpoint icon rotated by the bearing.

[bagolu]

Not sure it is usefull : the 4 beams are not at 0,90,180,270 and rotated: they depend on directions to next radio stations
I guess you can ignore my request and leave the userpoint import as it is : we can already set the usefull information as text/comment.
The airspaces is not a bad thing to display the directions.

Of course, if one day you rewrite the other navaids system, maybe this could be taken into account :)
Thanks for the quick replies !

There is still the issue #1031 as a reminder. Have to see what can be done.
