Not at this moment.

With the release of Alpha yesterday, the team is focused on addressing any issues related to the download and install of the updated alpha build. Once we’ve completed that process (~ 1 week), we will focus on assessing the current alpha participation. We appreciate all the great community feedback from our posting of the Build Change List, we will continue to release these notes going forward.



Here is an update on the current postponed deliverables:

  • EARLY APRIL – Feedback Snapshot update.
  • MID APRIL – Partnership Series update will be released.
  • LATE APRIL/EARLY MAY – EPISODE 8 (IFR) will be released.



Yesterday we released Alpha Build The detailed change list can be found here.

The team is currently focused on resolving any issues from the release of the latest Alpha build. We expect this process to take about a week before we will shift attention over to the Alpha participation.

For those currently participating in the Alpha, please make sure to check the weekly test requests post in the Alpha forums!



 We are currently focused on Alpha release tasks and will turn our attention to Alpha participation within the next week.

  1.  Ensure that everyone that received an acceptance email has access to the Alpha.
  2. Assess Alpha participation options for adding more people as quickly as possible.
    • Prioritize access for those that registered early for pre-release build testing.

Posted by: Microsoft Flight Simulator Team


ALPHA BUILD is now available!

Please make sure to launch Alpha build, check for updates, and install most recent Alpha update.


Welcome to the 1.2.5 version of the Microsoft Flight Simulator Alpha! In this update, you will find new content, bugs we’ve addressed, and an updated list of known issues.

A note from the development team:

First let us start off by saying “thank you”. We truly appreciate all of the amazing feedback we’ve received since the last Alpha release.

For the build notes, we have the following sections to suit the interest levels of our community, after this introduction we have the new content, below that the bullet point of changes, and for those who wish to have a more technical breakdown, members of the team have given an editorial on certain aspects of the sim.

You will notice that we’ve made several fixes based on your feedback (Review patch notes below). Your feedback is integral to our development of Flight Simulator, and we encourage everybody to join in, providing feedback via the Weekly Feedback Testing Category.

Based on the large amount of feedback regarding peripherals, peripherals support has been improved, and we’ve added more device binding presets. Please note that due to these changes, the previous mappings from will no longer work with this updated Alpha. We apologize for any inconvenience this may cause.

Finally, we know there have been a lot of questions regarding airliners, and we’d like to take a second to address the current lack of airliners. We are hard at work putting on the final touches and want to make sure we get the core functionality of the airliners “right” before we release any into wild. We promise that they are on their way, and we will let you know as soon as they’re cleared for departure.

Thank you for being a part of our Alpha, and keep that feedback coming!

:arrow_right: A look into the minds of our pilots and engineers!

We have worked on some of the causes for ground instability. In FSX Ground Effect was calculated once per aircraft at the CG of the aircraft. The closer the CG got to the ground, the more the aircraft’s lift coefficient was scaled up (up to 25%). To get more realism, we changed this to calculate the ground effect separately for each surface of the aircraft. This reflects reality better as one wing may be closer to the ground than the other and be more impacted by ground effect. Also, because the FSX ground effect was still referring to the CG coordinates, we now calculate the collision distance between each individual surface and the ground. And with this fix we now get a different and better lift coefficient scale for each surface. This helps ground stability because when the plane starts rolling on one side, that side immediately gets closer to the ground and then gets more ground effect. The other side immediately loses ground effect. This tends to push the aircraft back toward a level horizontal position.

We have worked on roll stability, which is the consequence of many different aspects of an aircraft. Including dihedral, wing sweep, CG and wing position. One particular aspect we added is that high wings have up to 5% more “effective” dihedral giving them more roll stability. So, we added a system that automatically adds “effective” dihedral depending on the vertical wing position. This adds more roll stability to our all high wing aircraft (C172, C152, GRAND CARAVAN, …). This does not however affect low wing aircraft. Mid wing aircraft will get a little bit of this. Low wing aircraft however already usually have a higher actual dihedral which compensates for this. For all high wing aircraft, there is now improved dynamic roll stability. The effect is not super strong, but from a 30° bank, they will tend to slowly return to a neutral bank, the strength of the effect fades as the bank approaches zero. This helps with an overbanking tendency and improves roll stability.

Improvements have been made to takeoff trim, and the effects of wind when on the ground, which makes take offs more realistic and significantly improves the wheelbarrowing effect that sometimes happened.

Work was also done to improve the effects of winds and turbulence with all weather.

We’ve also been working hard on peripherals. While still WIP here are some updates:

  • Categories are minimized by default
  • Added a button to collapse/expand all categories
  • Categories keep their state (collapsed/ expanded) when switching devices
  • Improved controls settings menu performance (but more WIP)
  • Improved sensitivity menu (curves displayed)
  • Essential controls sorted
  • Added user input preset management
  • Better default mappings for more peripherals

We know there’s more to do and the team is working on things such as:

  • New search bar layout in the controls settings menu
  • Improved sensitivity and dead zone curves (algorithm update)
  • Inputs displayed in the same fashion as notifications in the controls settings menu




Women’s History Month: The First Women’s Air Derby

Posted by: Microsoft Flight Simulator Team

So far this year, we have focused on utilizing groundbreaking technology to bring you our latest version of Microsoft Flight Simulator. Our Feature Discovery series has highlighted our aerodynamics, live weather, world-building and more. In our pursuit to build a beautifully realistic and expansive sim, we would like to give credit to the early pioneers of flight; specifically, the brave women who entered the field of aviation. They have paved the way for flight enthusiasts today, setting precedent upon precedent.

From left to right: Raymonde de Laroche, Hélène Dutrieu, Lilian Bland’s “Mayfly”

In 1910, Raymonde de Laroche, became the first the first woman in the world to receive a pilot license when the Aero-Club of France issued her license #36 of the Fédération Aéronautique Internationale.  Hélène Dutrieu, the “girl hawk” of aviation from Tournai Belgium, set many altitude and distance records including winning France’s Coupe Femina for the women’s world nonstop light record on December 31, 1911 flying 254 kilometers (158 miles) in 178 minutes. In Northern Ireland, Lilian Bland designed a glider, the Bland Mayfly, even before she earned her pilot’s license, making her the first women in the world to design, build, and fly an aeroplane. The United States wasn’t far behind, and soon women all over the globe took to the skies despite the challenges they faced due to gender norms.

From left to right: Louise Thaden, Gladys O’Connell, Ruth Nichols

Circa 1929, when there were as little as seventy licensed female pilots, one of the most revolutionary races began in the US: The Women’s National Air Derby.

It was more than a race; it was a chance for women to finally show the world that they could fly.

These women spanned from aviatrix record breaker to Hollywood starlet to the wife of a preacher, but they all had a common message to spread: women were fiercely good at flying, and they would prove it. To qualify, they had to have at least 100 hours of solo flight, with a minimum of 25 hours of cross-country flying.

As the idea of letting women fly was not commonly accepted in the 1920s, there were many restrictions in the first race, such as access to only slower and less powerful aircraft.

It was an early morning in August where twenty women put on their flight gear, climbed into their cockpits, and raced across America from Santa Monica, California to Cleveland, Ohio. Navigating the 2700-mile course with only road maps on their laps, they started their journey.

Only 15 out of 20 women finished the first Women’s National Air Derby in 1929

The race itself was something out of the movies — Questionable mechanical failures, threats of sabotage from outsiders, two crashes, and one case of typhoid fever. The threats of sabotage and protestors sported signs with phrases like, “Race Should Be Stopped”. Blanche Noyes, a non-smoker, had to put out a fire mid-flight and later found a cigarette butt in her baggage. Pancho Barnes crashed into a car that drove onto the runway as she was landing. Claire Fahy’s wing wires had mysteriously been eaten through. However, despite some of the mishaps, the pilots decided to stick together and finish the race.

“What chances we took in those pioneer days of flying! What narrow escapes we had during takeoffs and landings on the many rough, short airfields of the twenties!” — Ruth Nichols, Derby Contestant

A crowd of over 18,000 people gathered at the finish line in Cleveland to greet the pilots. In the end, Louise Thaden finished in first place with a time of 20 hours, 19 minutes and 4 seconds. In third place was famous Amelia Earhart.

Racers from the 1929 first women’s air derby

The race was their first chance to meet face-to-face as women pilots and set the stage to carry on the legacy. Many of the women banded together afterwards to form The 99’s Club (now known as The Ninety-Nines) to celebrate women in aviation all over the world.

We salute these outspoken and brave women as we continue to develop Microsoft Flight Simulator and hope we can empower more females to pursue an interest in the field of aviation. To everyone, thank you for your passion and love for flying. Your enthusiasm has made our sim efforts possible.

 It is with immense pride that we stand with our community during this very challenging time. We continue to prioritize the health and well-being of our team, friends and families. We do so with an unwavering commitment to remain connected to the community as we continue to develop the next iteration of Microsoft Flight Simulator. Your feedback, support, and encouragement continues to be an invaluable inspiration to the team.

With guidance from our leadership, we have taken steps to establish remote work spaces that will minimize impact on our development efforts. We have prioritized team focus on key deliverables core to completing the project, while pausing work on deliverables that are not. In the near term work will be focused on delivering an updated Alpha build, followed by assessing our Alpha participation. Once we’ve completed that process, we will turn our focus back to other deliverables we have in the pipeline (e.g. Feature Discovery Series Episodes, DR Roadmap Updates, Partnership Series updates, etc.). This is a temporary measure, we will continue to monitor the situation while providing frequent updates to the community.

 For now, expect that many of the deliverables we’ve been working on will be delayed by a few weeks while we get the team working at optimal efficiency remotely.

 In moments like this we are mindful of the importance of taking care of those that take care of us. From all of us, to all of you, we wish you good health and safety.  

 We are all in this together.
