Guten Morgen Dirk,
as I wrote before, there is no real value for the ranges available in the ARINC424 source, only the type and power of the navaid. There are FAA minimum recommendation which we used till 2108 for the MSFS because the MSFS expect the ranges in nautical miles.
FAA minimum VHFNavaid ranges:
So, we have set 25,40 and 130 NM till AIRAC 2108. Due several requests and the fact that in real-world in some areas the ranges are extended, we have decided to use a real-world range-table from AIRAC 2109 on. That means in MSFS (and only in MSFS because no other addon uses these value) we have set the ranges more or less to realistic ranges. Therefore the increasing range from 130 to 195NM … 130NM is the minimum guarantee signal strength for a high-altitude VHFNavaid (see the FAA table), but in real, the signal can be receiving above the 130NM minumum range.
LNM doesn´t have this conversion table, LNM can only be used the SSV Designator to identify which type of navaid it is (terminal, low or high) and depending on this LNM will set the correct FAA minimum 5, 40 or 130NM. That´s the different.
You see this very clear in your examples, when you switch on/off our database:
WRB with Navigraph database, defined as high-altitude navaid (H) with 130NM
WRB without Navigraph database (using only the MSFS data), defined also as high-altitude navaid (H) but with a range of 195NM
Again, these values/ranges come from another real-world source and are not part of the ARINC424 so, LNM can´t show other ranges as the recommended from the FAA.
To your second question about the double procedures:
LNM doesn´t filter out the MSFS stock procedures, therefore you see both the procedure from the stock-data and the Navigraph data. When you look on airports, where no procedures are available in the stock data (ie. NZWR), you see the procedures only from our dataset:
comparing an airport, where stock data are available - you see the double entries:
So, this is more a LNM limitation then a navdata issue. In our dataset all procedures are only once …
Hope that helps,
