Live Weather Does Not Match

I’ve had 110 knots headwind at 30k, flight was fine but GS was kinda slow lol.

Where were you flying?

Don’t remember but not in a hurricane :slightly_smiling_face:. Wheather was fine though. High altitude winds have been a problem in FSX, too.

Yes, I fly in Europe for now. Why should it not work outside Europe? This makes no sense. They should fix it as fast as possible if it is the case. :sunglasses:

Agreed! It makes no sense at all :joy:. Europe is perfect for me. I fly in the US and the actual surface conditions are hit or miss. The winds aloft are always the same there though haha! I think my temporary solution to save myself frustration over this is just to fly and explore Europe for now!

The worst part of Live Weather, is I finally log into a game that gives me the real stormy weather, I take off, fly around a bit and land (and in wanting to test how another performs), exit to main (game) menu, select the other plane, log back in, and frown at my disappointment in that the same airport that I just landed in, that had crosswinds (yes; something other than 223 3kts), heavy rain and lightning, is now clear as day as far as the eye can see in no less than 3 minutes it took to select a new aircraft and load back in.

At this rate, if I get lucky with getting “real weather”, I should just use developer mode to change aircraft.

which areas, country?

It depends where you fly. In many parts of Europe, the wind part of live weather works. In the US and many other places it does not.

There are three main bugs in live weather.

  1. If you spawn at a given airport after launching the game with live weather enabled, you will get live weather, but it may not always correspond to the current real-world METAR. But, if you back out to the main menu and select a different airport, or change aircraft, the live weather will be disabled when you reload. Winds will be calm, skies clear, pressure 29.92 and temperature will be around 13 to 15C. If you want to move to a different airport, or switch to a different aircraft, you have to completely exit from the simulator and start fresh.

  2. Even if the live weather works, if you load at a US airport, the wind will always be 225 at 3 degrees. This bug also happens in other areas, including the Philippines, Japan and Australia. The winds do usually work in Europe, Africa and South America.

  3. Even when live weather is fully working (including wind) the airport ATIS does not give correct information. It might report the lowest in-game cloud layer, but gives the wrong altitude. It will also report “few clouds” at two other altitudes, even when there are no clouds. Even when wind is working, ATIS often reports the wrong direction and velocity. It always reports the dew point as “10 degrees” no matter what the actual dew point is.

Hi!

it’s an illusion! Indeed since days the wind injection seems to work better for some mysterious reason, especially in Europe and in many other spots in the world but even if the winds are correctly injected (somehow) it doesn’t seem to affect the airplane in anyways or barely…

See in my video from scratch, as i noticed many times like yesterday in Taiwan at RODN as it was, of course not recommended to fly a GA in those very severe stormy weather conditions, gust at 50kt and crosswind 16032G50KT, even a 747 won’t takeoff/land for the sake of safety, watch my video bud and you’ll see that with MFS2020 you are able to take off/land a Cub or a DR400 with a 50kt crosswind!

I made the same “flight-test” with Xplane 11/Active Sky, it was impossible to stay straight on the runway for the rolling T/O, in order to make the landing-test I did take off without the weather that I injected once i was in the air, I crashed before landing on final consequences of the big time stormy weather and very strong gustwinds!

Again in MFS2020 winds could affect your indicated airspeed so it gives the illusion that it “works” but it doesn’t affect your envelope/flight-model in anyways as it’s supposed to be in order to simulate the reality and the impact of the weather as much as possible (as the advertisings promised to us) … Period.

It’s terrible because there is no voice from the devs who seem to care about the huge failure/bug/issue!

In your video, you are experiencing the 225/3 wind bug. The bug does not mean that the winds are not being injected into the environment. The ocean clearly shows the effects of the strong typhoon winds. Users flying in Hurricane Laura on the US Gulf Coast last week saw the same thing. The water in the Gulf clearly showed the effects of the wind with large waves and whitecaps, but because this is an area that always has the 225/3 bug, the aircraft acted like the winds were dead calm.

The essence of the bug is that the aircraft acts like it surrounded by a bubble of completely calm air, and this prevents the wind from having any effect on the aircraft at all. The only way to know for sure if the bug is active is to enable the wind display on the G-1000, which will show you what wind the aircraft itself is “feeling”. In your video I did not see the wind display.

In places that are not affected by the 225/3 bug, like England, the aircraft absolutely does respond to the wind. Early last week, the entire UK was being affected by a storm that had very strong southwest winds at the surface and aloft. I did a flight from Heathrow (EGLL) to Manchester (EGCC). On takeoff from Heathrow runway 27R in the C172, the wind display in the G1000 was showing the wind at 210 degrees at 25 knots, and the aircraft very definitely did experience the strong left crosswind. I had to hold almost full left aileron into the wind on the takeoff roll, with compensating right rudder to avoid being pushed sideways. As soon as I became airborne, the aircraft immediately begin drifting to the right, and I had to crab about 20 degrees to the left (into the wind) to maintain the 270 degree runway heading. Throughout the climb to my cruise altitude of 6000 feet, the aircraft was continuously pitching and rolling in strong turbulence. (The winds aloft at 6000 feet were almost 60 knots).

If anything, the turbulence effect in MSFS is probably overdone, but in places that do not have the the 225/3 bug, the aircraft definitely does interact with the wind.

Again, you cannot go by what the airport METAR might say, or by what you see out the window (like large ocean waves). The only way to know if the 225/3 bug is affecting the aircraft is to enable the wind display on the G-1000 for those aircraft that have that feature. There are three options for the wind display - you would want to choose “Option 3”, which gives the most detailed information about the wind speed and direction.

I tested a number of airports yesterday in this post:

Am finding that it’s more complicated than just the 225/3 issue. Almost everywhere, wind speeds were less on the ground than what they were supposed to be. To date I haven’t been able to find anything over 15 knots ON THE GROUND, but maybe I need to try the UK when the next storm comes through.

MSFS does appear to model the affect of ground friction on wind speed, which is a very real phenomena, but it might a bit overdone at present.

All airport wind observations are taken at a standard height of 10 meters (31 feet) above the ground, and due to ground friction, the wind at the surface will always be less than at 10 meters by a certain amount. It depends on the type of surface. Grass and dirt will have more of an effect than concrete for instance.

MSFS also seems to have an unavoidable gust factor built into surface winds, whether set manually in the custom weather menu, or provided automatically by live weather.

Due to the gust effect, surface wind always appears to fluctuate in both direction and speed. In the manual weather settings you can control the amount of the gust effect, but you cannot turn it off completely.

Agree on the fluctuation and speed decrease due to ground friction, am glad they modeled that but as you say it may be too aggressive.

I had done a flight out of EHAM last week where the wind was supposed to be nearly 30 knots, but it was only showing as 6 knots. Climb up above 200ft AGL, and it would increase to the correct speed. Descend back down, and it would go back to 6 knots. Even tried this over water where the wave height clearly indicated a 20 knot plus wind.

When I flew into Laura I had the 225/3 issue and the water was calm and didn’t show any white caps or anything.

Yes, in and around the US and Canada (and other places) it is completely bugged and you can’t really do any analysis. It defaults to the 225/3 no matter which altitude your at. What I’m saying is that I’m seeing a speed drop off at the ground even in places where it is working better.

This seems to vary from user-to-user. I gave Laura a try when it was just offshore from making landfall, and the Gulf showed really big waves, and there were major cloud formations, but the wind at the aircraft was the usual 225/3

Yeah I got the rain and clouds, no wave action and bugged wind though :frowning: .

I concur that this has been my experiences.

Hi,

Tks for your feedback! Indeed I was a victim of the 225/3 ! The fact is that i decided to fly the XCub because the map was indicated the wind matching with the METAR so I thought that the wind was injected correctly.

I just made an other test, almost the same bad weather today as yesterday at RODN, I just tested it on the ground with the DR400NG and the PFD indicated 225/3kt!
I will edit my video to be more accurate even if it doesn’t change the meaning somehow, still no turb and winds where it is supposed to be in certain severe weather conditions CB/TS etc

Good to hear that Meteoblue shared the information with Microsoft and work on it!
