For months now I’ve yet to get a flight plan to be the same in both LNM and MSFS. I subscribed to Navigraph in hopes that would cure my problem but no luck. It doesn’t matter whether I create the plan in the World Map or in LNM, the route flown in MSFS doesn’t match the route in LNM. Is there a way I can create a route that will be identical in both?

I create my plan in LNM first, then hand enter my plan in MSFS. I have about an 85% success rate. Some waypoints are missing in MSFS, even with a Navigraph subscription.
Hi,
please can you report this in our forum with a flightplan, where the waypoints are missing?
Because this is exactly the benefit to have one unique worldwide database for all addons, to plan a flight in tool A and to use it 1:1 in tool B.
There is a know issue in the sim, where waypoints will truncated, therefore I’m curious if this is here the case or there are really missing waypoints.
Have you tried it ti find it on the woldmap with the search function?
Cheers
Richard

Hmm. I also use LNM and have Navigraph updates for both LNM and MSFS.
I just use the LNM export function then in world map more-> load.
The route line matches although the waypoints are not listed just below the airports. However when I load into the game the waypoints are in the Garmin.
Never had an issue with it not matching 🤷🏻

You can make LNM use the MSFS database instead of that of Navigraph.
Despite both should be the same if you are subscribed, I find it safer when I have my LNM use the database of the sim itself, which will ensure your flight plan will use the very same data as the sim itself.
Then I export the flight plan as a MSFS flight plan and load it in the sim.
The documentation for LNM says that you must use the Navigraph data exporter (the name escapes me right now) to install data in LNM if you have installed Navigraph data in the sim.
(I probably don’t explain this well, but the LNM manual does).

Prior to SU5 I tried to create the same flight plan in Navigraph, SimBrief, LittleNavMap, SkyVector, and MSFS World Map flight planner without success. I’m sure the navigation databases are different but they should be similar enough to create very similar flight plans. Even if the waypoints, navaids, airports, SIDs, STARs, and Approaches are in all the databases, the flight planners create different routes. SimBrief and SkyVector match the best because they both have suggested best routes.
Why do you want them to match? Why do you use both? Either LNM or default planner.
I use simbrief and so far had no problems. Even using the older airac.
Hi
I too first plan in LNM as I find it produces a low altitude route with a FL applicable to my EMB Banderiante…or Cessna Caravan (blame Air Hauler lol)…where as MSFS planner produces sometimes a plan with an airway with a height restriction and doesn’t take my aircraft into account …LNM avoids this using the route finder with a chosen altitude.
I then load into MSFS planner and change the SID and ILS and Approach fix and MSFS will then closely follow my LNM but will choose a more direct route which might include as above a airway with a inappropriate FL for my aircraft and this is where I then edit the route to match the LNM plan where needed.
To date I have been able to 100% recreate my LNM flightplan, yes sometimes a waypoint is hard to find and here I use the search function and to date have always found the Corresponding LNM waypoint.
For me this works very well I follow my LNM plan fully and avoid ATC directing me to an impossible FL .

I use LNM to track the flight, TOD, crossing altitudes, airport info, all kinds of stuff.
Me too but the question was why you use them both? Use one, plan the flight in LNM and enter it into MSFS.
Personal observations:
So, a couple of things that will address the OP -
There are several factors in play here:
-
What NavData you are using - depending on your region, the differences are less pronounced in the US now than they were say last August.
-
The sim has an independent Flight Planning Logic, and now so do the NavUnits if you are using say Working Title’s CJ4 or G1000 NXi. More on that in a minute.
-
LNM needs to be reading the sim Navdata to get to the “Closest Match.” Spoiler - you won’t get an exact match between LNM and the sim Flight Planner.
Navigraph vs. NavBlue - I’m not going to go down this comparison road, there are many more posts about this. Suffice it to say, when MS-Asobo pushed down the FAA AIRAC data, the gap between the two database shrank materially, as long as you fly in US regions. 'Nuff said on that.
The sim’s independent flight plan logic will insert non-standard and unpredicted waypoints in response to certain plans that have procedure legs the sim isn’t programmed for. That’s why you have these oddball USR waypoints. In short, the flight plan on the sim planner page will never 100 percent look like a plan you created in LNM, especially if you have procedure legs it doesn’t understand.
This is where Working Title comes in. They built a separate flight planner inside the CJ4 Mod, and that same technology is now in the NXi. That’s the only way they could invoke procedure legs that the plane could now perform through the NavUnit - things like Holding Legs. So depending on which WT unit you are using, LNM and the WT MFD FPL will look real close. But the sim Planner never will.
That’s why Asobo brought on WT - to fix this among other things. Each Garmin (G1000, G3000, G3X) and the Rockwell Collins Proline on the CJ4 will have independent flight planner logic and capabilities, so they can act as close as 1:1 RL features.
LNM should by default read whatever NavData is currently active in the simulator - NavBlue or Navigraph. There are rare times someone’s configuration is not looking at the sim, and therefore they’re getting things like missing runways, approaches, SIDs/STARs. Double-check LNM is reading the sim. And for Navigraph users, there is an FMS Data Manager (separate from NavData Center that downloads Navigraph to MSFS) - the Data Manager can update the AIRAC information inside LNM.
There are other complications and factors, but the above addresses the OP’s immediate question.

There could be multiple factors that could cause this, but I’ve discovered a few workarounds regarding how FS handles certain flight plan imports.
My first question to you is, what type of plans are you having issues with? Is it VFR, IFR, or both?
First of all, I only generate a flight plan one place so if I generate in LMN I load it to MSFS in the world map. If I generate in MSFS I save it and then load the saved plan to LNM.
The flight plans are IFR and flow either in the TBM or Longitude with the current aircraft mods and the latest G3000 mod.
I did a little more experimenting today. Now it gets really strange. I looked at the waypoints in the .pln file that I loaded to MSFS and they were all correct. I then loaded the plan in the world map. The nav log was correct. Looked at the FMS route and it was correct. Took off and activated nav mode in the autopilot and viola, the waypoints in the FMS changed from the original to something completely different. They still got me to my destination but not via the planned route.
Now I’m even more confused
Something strange has happened since SU5 or maybe the first hotfix. Presumably one should be able to either import a flight plan from any source or create one on the World Map, load it into an FMS, and have it work correctly. I’m finding the same flight plan loading into the various FMSs are messed up. Waypoints, SIDs, STARs are mangled, sometimes duplicated. Then trying to have the autopilot navigate using the flight plan doesn’t always work. The autopilot goes way off course. The same flight plan should load and work the same in all aircraft and autopilots even if they contain “internal” waypoints for climb and descent. Also, the flight plan, the FMS, the NAVLOG, and the VFR Map should all match but they don’t. I can’t trust the autopilot any more because I’m checking every minute to see if the autopilot is wandering off course.
I’m learning all this, and was getting quite frustrated by the SIM not following LNM flight plans. Thankyou for your detailed explanation.
