In game landing analysis for Microsoft Flight Simulator 2020.


Bouncing after landing is now detected + G's a bit higher + Hide button + A bug fix.

For changelogs, please check the releases.

How to Install/Use?

Download the latest release from here (Assets -> File-that-is-not-source-code.zip). Unzip to your favorite location for MSFS2020 landing monitors, and start Gees.exe. You'll see a window like this in the bottom right.


The app itself runs in the background, and you can find this status window in the status tray, as this icon:

Trey Icon

That's it. When you start the sim the app will automatically connect and when you land, you'll get a window similar to this slide out top-left:

Slider MSFS view

You can start it before, or after the MSFS, it doesn't matter.

How to Uninstall?

Delete the folder where the Gees.exe resides.

What is measured?

Descent rate at the landing in feet per minute

Self explanatory.

G force at the touchdown

Maximum G force impact at the moment of touchdown. Should be in theory related to the descent rate, undercarriage dampers and how much the passengers are nervous.

Airspeed and ground speed at the touchdown

Self explanatory.

Wind speed and direction at the touchdown

There's a nice arrow, showing where the wind is blowing from

Sideslip at the touchdown

Did you do the proper de-crab maneuver, or the plane is going sideways on touchdown in the crosswind? The higher, the worse. Keep it close to 0 degrees or you might break the gear, or pop the tire (well, probably not in the sim).

How to compile it

It's a c# WPF application. You'll need a Visual Studio with .NET 4.7 and the following nuget libraries:

  • Version 1.1.0 November 01, 2020

    New Features
    Bouncing the plane on landing is counted now as a bounce, and not as a new landing.
    If you are landing like this, you won't get 5 average landings anymore, you'll get one with 4 bounces. This required some changes in the interface:

    You have bounce field now in the display
    Auto-close timer is now also the "bounce" timer, meaning that you have this amount of time to have the plane rolling before the app will start to check for a new landing.
    There is also a bounce parameter in the log.
    The log is updated to v3, to have the bounces: you still have the old landings accessible in Documents\MyMSFS2020Landings-Gees\landings.v2.csv, but they are not shown in the app
    Landing detection much more sensitive
    To accommodate this new bounces, and to try to fix the bug where the app did not detect landings sometimes, I made the landing detection to be much more sensitive - previously, you needed to have the wheels firmly on the ground for 100ms to be "landed". Now, you need to just touch the ground.

    G's a bit higher
    All for this bouncing - G's are now not average G force over time, but maximum impact (by sim frame). The values will be higher.

    Hide button
    There's a button you can use to hide the app without quitting. You know if you needed it.

    Sidebar color
    For all of ye that once you see something you cannot unsee it, the bar is thinner and more sky coloured. I can't remove it completely and still have it accessible by mouse click, so I think this is better than having a floating button somewhere.

    I think the bug where when you start the app before the MSFS, it does not detect the landing, so you have to re-start etc... is fixed. Not sure though since this thing works pretty well when I try it, and then later it doesn't. And I need like 5 mins to start the freaking game for each of these "tests"...

  • Version 1.0.0 October 22, 2020

    Major update under the hood:

    The landing rate should now reflect the landing rates calculated in-game, in the landing challenges.
    It is read from the sim directly.

    How to install:
    Download the Gees_1.0.0.zip, unzip, and run Gees.exe

  • Version 0.3.2 October 14, 2020

    If you experienced broken Landing History data, this should fix it.

  • Version 0.3.1 October 13, 2020

    How to update:

    Delete the previous app folder, download the new zip, unzip, and run the new version.

    This is a major release, so there might be some breaking changes. If it doesn't run, please revert back to 0.2.0, and report the problem here, on Reddit, or on flightsim.to

    New Features:

    Nicer animations works well on al Windows DPI settings.
    You can choose the duration of the popup before the auto-close, or don't do auto-close at all

    You can always revoke the popup with the last data, by going with the mouse in the top left part of the screen. A tiny line will be visible there.

    There is now a landing history, stored in Documents\MyMSFS2020Landings-Gees as .csv file

    Bug Fixes:

    No more wonky layouts on different "Scale and Layout" settings. I moved the code from 2001 to 2020

    There should not be a false landing triggered when you go back to the main menu in mid-flight.

    I don't know, but I think Gees shows the impackt of the wheels onto the ground and not the spring-loaded impackt of the cabine.

    Can you maybe change it that when you look into "My Landings" and filter for time that you have it correctly sorted by e.g. changing somehow the timeformat.
    And a Bug yo may have noticed by your own is that if the report pops off and you click it away, it shows up again for the closing animation.

    The app is verry cool, but sometimes in the replaymode, it shows other datas of the landing. Why?
    • afffe18
      18 day(s) ago
      because the replaymode shows not exactly how you flew but it places the plane where and how it was when you recorded. So it flies the plane on its own and than the landings aren't exactly like they where before, just very similar.
      So it's not an issue of this app I think.

    Need to see curves for all parameters by double clicking an entry from the "My Landing" view. The tool actually only show parameters at touchdown, we need to see at least the fpm curve; heading curve, G curve, ...

    Really, really enjoying your Gees add on for MSFs20
    I’m new to all this... what kind of figures would be a good benchmark to aim for if sim landing a Cessna 172 in good weather conditions?
    Thanks in advance

    Great tool! Will you update so the results can be seen in VR! Thanks!

    Very useful little tool with some minor issues. For example I´d prefer to have an option to disable the white line on left side of my screen. Apart from that, it´s a nice little program to have.
    Well done!

    Decent app with huge potential. Couple of things: 1. Could you please make an option to disable the blue line on the top left of the screen? That is an immersion killer for me. 2. I found that sometimes the scorecard would pop in and out in the middle of a flight in the air randomly for a half second or so.

    "How many passengers are nervous"
    How do you know if they are nervous?
    Are they glass?
    I did a -78 FPM touchdown with the Cub and it said "2.06G"

      Yeah, the taildraggers are sometimes not accurate, I noticed that.
      As I mentioned many times - I'm not inventing the G's, but reading them out from the sim. I have no control over the things that are not simulated well, or if there's a glitch during the landing or whatever.
      There's a disparity definitely between the G's and FPM's sometime. I would say that the second is more often wrong than the first. But G's also are not accurate sometimes, especially for the taildraggers.

      Also - G's are not just vertical. Also lateral/roll force is counted. So it might be that.

      Or it's the frowning face? I was thinking of removing that tbh.
