Vastly Different Flight Plan Results from In-Sim EFB vs. Web-Based Flight Planner

Ater thinking about the IFR plan that I was given by the “Find Route” button via the in-sim EFB, I decided to try the web-based Flight Planner.

I am very surprised by what I found – two vastly different flight plans:

This is what the in-sim EFB gave me:

This is what the web-based flight planner gave me:

Is anyone able to shed some insight as to why this would be?

Then import then into the sim 530 and see what you get. Most of the time my enroute nav point disappear in sim.
I have to enter all my plans in sim to be reliable. Even then…

Yes, I have seen that and wrote that up as a bug this AM.

Oh, and for the record, on the in-sim EFB, I did go to the Flight Details tab and set the flight as IFR.

Oddly, I note that on the main page on the web-based planner there are buttons on that main page for selecting VFR/IFR and there is also some on the Flight Details tab.

On the in-sim EFB I only see the switch on the Flight Details page.

Is it stuck in VFR in-sim?

Also there was a major failure with the plane missing the ILS. I let it do it’s thing to see where I’d end up and it nosedived into the ground a couple hundred feet from the runway. Never had this issue in 2020

Each flight planner app and efb have their own proprietary software to create routes. Usually one isn’t better than any other.

The new 2024 EFB will take some time to figure out. It has limited import/export capability with other flight planner apps. It is possible to manually enter the flight plan into the EFB or the aircraft.

Naturally, but in my OP these are both from the same developer — Microsoft/Asobo/Working Title, which makes the discrepancy all the more odd. The in-sim and web-based should be using the same base code and be pulling from the same nav data.

It isn’t like I’m comparing the native MSFS 2024 flight planner to SimBrief or Little Nav Map or some other flight planning tool — I’m comparing it to itself.

Should be? YES but if no, is it a bug or a feature or wishlist?

I hope they are both using the same AIRAC data!

Glad to find this thread as been going crazy with the 787 EFB and autopilot. I had a number of plans made on SimBrief for 2020 that pretty much worked. However, when uploaded to 2024 I cannot fix discontinuities and actual flying is pretty hit or miss… like miss the ILS.

Autopilot button seem unreliable.

I am not familiar with the MS planning web-based tool? Is this now “Best Practice”. Entering by waypoint is a non-starter.

Is the G1000 more stable that the airliners autopilot?

Any guidance would be appreciated…

I don’t know what best practice is. I was just really stunned to see just how differently the in-sim vs. the web-based put together a plan for me.

It’s like I was using two tools developed by two different companies using two different sources of nav data.

Thanks, ran into a basic video too.

Well, I have an IFR rating and the 787 in 2020 was my goto long haul plane… like the wings… but I have to go over the procedures again to make sure I am doing things right.

KSCK is about 80 miles from SFO and far enough away that you can go up and down properly. I just entered a flight plan in the tool and brought it over to the sim. I was able to delete out un-needed waypoints on the approach.

Unfortunately, though I was able to get onto the route OK out of SCK using headings and LNAV, VNAV did not work and it did not capture the localizer glide slope though it said it was there/next on the flight director. The altitudes were there on the Legs in the autopilot… buttons not very responsive.

I believe VNAV never worked well in 2020 either. I forget what I had to do to capture the GS but it was a funny dance between LOC/APP modes.

Given the general state of 2024 I am probably asking too much here and best not get frustrated. Maybe could fly it in the 172.

The 787 was also a bit choppy in the FPS category whereas my 172 is smooth.

Yesterday I wanted to fly someplace new to me where I have no add-on scenery that would be inadvertently streamed to my Series X, bogging it down rendering stuff. So I chose Spain, Coruna to Madrid, two handcrafted from that World Update. That should, and did, look good in 2024.

Now I like to play with maps, so I started in Navigraph just to get the lay of the land (Spain) and see what made sense to me for a short flight in the 2024 VisionJet (not the legacy version). Once I had the route I wanted to fly, I duplicated it in the web based flight planner; easy peezy, done in a few minutes. Not the process I would recommend to anyone, just my own map fun…

Opened the EFB in 2024 to pull in the flight plan from the web based planner, sent it to avionics, and started the flight on the runway per routine. This is where it gets weird. The route in the Garmin was only partially what I planned. I pulled up the EFB in the plane and resent to avionics. Same weirdness. Where did those waypoints come from? And why were some of mine missing?

No matter. A very short route. Deleted unwanted fixes and added back my own. Overall not a reasonable process. Wondering if I failed to select VFR somewhere along the way? It looked like some game AI was second guessing the flight I was attempting and tried to fit my plan into some other parameters that I did not specify, but that is a wholly wild guess. Time will tell?

There really seems to be some confusion and oddities here between the in-sim EFB, web-based flight planner, nav data and avionics.

It’s hard to understand what is going on, but something is awry with their interdependencies.

This web-based flight planner is a really nice tool.

I’m sitting here, enjoying my morning coffee and doing a more thorough job of exploring it.

I wish I could understand what the reason is for the in-game one generating such a different flight plan from this web-based one.

It is really quite odd.

Okay, this whole thing is totally screwy.

I entered the same Origin/Destination as I did in the OP, only this time I am really looking at it carefully.

Look at this crazy. I have circled in blue where my origin is and red where my destination is:

Why is it sending me THREE states away to Montana and having me, then, fly back to Lake Tahoe???

No wonder this flight plan is vastly different than the single-waypoint one generated in-sim.

This is nuts.

To reiterate. All I did was enter an origin of KPRB, a destination of KTVL, I clicked the Auto-select buttons for departure, approach and route and this is what it generated for me.

Duplicated your flight and got the same cross-country as you did. :cry:

FWIW I successfully copied a Skyvector flight plan and the planner put it in. I would assume other 3rd party app flight plans (text) can be pasted since there is no import/export.

BTW the navigation database is different than the one in FS2024.

Thanks for checking that out for me. I wonder if there are far more instances where something like this can occur.

I have an answer for the why:

Based on what Matt has shared, it seems that the web-based planner is a far better solution for flight planning than that of the in-sim EFB.

It is a better solution, but one part of the process should be verified. After creating the web-based plan and then jumping to the EFB, this plan needs to be loaded using the LOAD button at the top, not the LOAD FROM PC button at the bottom.

My concern is if this LOAD process changes anything in the flight plan. I’ll have to check this out.

Also, it doesn’t appear to be any “export” capability to copy an EFB flight plan into the web-based flight planner.

Really, I need to create a wishlist item to request they establish the same flight planning logic for both the in-sim EFB flight planner and the web-based flight planner.

I was honestly shocked that they aren’t already the same. Why would they purposely choose to have two different flight planning logics? That is 2x the code, and 2x the confusion on the part of the end user; like what I experienced that inspired me to start this thread.

I also have issues getting the FP loaded into the avionics:
