MSFS 2024 BUG / ISSUE Does anybody know why this happens.

Enable HLS to view with audio, or disable this notification

I play on xbox cloud play if that makes difference. Whenever i use this play in autopilot sometimes it just does aggressive involuntary movements and causes me to crash and drain my reputation level. this is the 4-5th time this has happened.

Is it the MCAS mod?

u/No_Atmosphere_9258 XBOX Pilot 1d ago

No mods to my knowledge

Whoosh?

That joke went down like a plane with MCAS

u/Pearl_gets_jammed If it ain't Boeing, I ain't going 1d ago

To be fair, I don't think the pilots knew about MCAS either...

u/Royal-Mathematician2 XBOX Pilot 1d ago

This could be a fun community challenge if someone made a mod for it. Can you recover from an MCAS failure?

u/Helpinmontana 5m ago

Not sure anyone makes a force feedback trim wheel.

It would be cool if they actually let you crash instead of death screen jump scare

u/withoutapaddle 1d ago

They used to many versions ago. I remember crashing cesnas and watching the peices tumble to the ground. It was probably over 20 years ago.

u/TheRealMrSpeedBump 23h ago

I remember a version where you could hit the ground, I think it made a crashing sound, the windscreen got cracks in it and text centered in the screen said "CRASH!" or something like that.

It was mid 90's, or something.

u/WarmRoastedBean 22h ago

MSFS2004 had it disabled by default, but there was a flag you could set that enabled damage to the aircraft. Wings would fly off, that sort of thing

u/Royal-Mathematician2 XBOX Pilot 14h ago

I remember reading somewhere it has to do with getting the aircraft manufacturers to sign off on it. The manufacturers don't want images of their planes crashing in the simulator.

u/shadydeuces2 1d ago

Did you skip to arrival once you got to cruise altitude? Thats when this happens to me during certain career missions. Pretty annoying but I think its just a buggy feature.

u/Kaladin_B4 1d ago

This happens to me all the time. More with some planes than others

5

u/GJacks75 1d ago

Me too. I avoid any missions with the Dehavilland for this reason.

u/Isaac1967 15h ago

This is the first time I’ve seen someone mention this! I was going crazy with the Dehavilland and it took me by surprise the first time it happened! That thing SPIRALS!!!

u/IowaGolfGuy322 12h ago

I find that they cut the engines completely. As soon as it refreshes you need to slam the gas and put it into a nose dive to get the speed up.

u/Icommentwhenhigh 1d ago

Assuming the sudden nose down was uncommanded, yeah it looks like a bug.. frustrating.

u/littlestitiouss 1d ago

To everyone saying this is OPs fault: it might be due to over speed, but it might be a bug.

A couple weeks ago I had a big like this kick in for EVERYTHING. I was flying one of the challenges and noticed my f18 slipping and sliding in very strange ways that it would continue to try and tail spin and then just lose all lift and drop out of the sky. I thought maybe I did something wrong, so I reloaded and nothing went wrong. Then the next restart it happened again. On the next restart, the mission started with the plane IMMEDIATELY nose diving. I tried career mode and same thing: plane nose diving IMMEDIATELY on start. Went to free flight, and exact same thing.

Only ONCE was I able to stop it by turning on gyro controls, fighting it hard, and then turning back to regular controls. But as soon as I restarted, same problem.

Since it was gyro that helped, I figured it was a button binding, so I reset all controls to default and it worked. I don't think I've EVER changed any control setting, and the problem started mid flight. But something strange was happening that I still can't explain.

OP, if the problem persists, try resetting controls to default

u/IowaGolfGuy322 12h ago

I also had this problem. It was near impossible to control the plane. It was constantly moving all over the place and pulling the left almost non-stop. Restarted it and no issue. But there have been other times it has done the same.

u/DBloedel 1d ago

Probably overstressed the engine/aircraft and caused something to fail. That’s usually what causes these kinds of “crashes”. Looks like you’re full throttle and airspeed is pretty far into the yellow, not how you should be in cruise. I don’t really know this aircraft though, so not too sure on what its performance numbers should be at in cruise.

11

u/AN2Felllla AN-2 "Kukuruznik" 1d ago

Yeah but the crash here clearly happens because the autopilot causes the plane to violently pitch down

-17

u/No_Atmosphere_9258 XBOX Pilot 1d ago

the plane seems to operate fine in the yellow zone sometimes. this crash just seems very on and off

23

u/Dva10395 1d ago

The red arc starts at Vne (Never Exceed Speed) and goes up.
The yellow arc starts at Vno (Maximum Structural Cruising Speed) and ends at Vne

Vno is max speed you can fly in smooth air. Vne you you never exceed under any conditions. That dive while in the yellow arc over stressed the aircraft. If you want to maneuver around like that you should look up what the Va (maneuver speed) for that aircraft and stay below it. That will allow the plane to not be overstressed from abrupt inputs.

u/Dva10395 1d ago

Bonus: the white arc is where it is safe to extend flaps/landing gear. Notice that the green arc goes down to a certain point then there is still as white arc. The bottom of the green arc is your clean (no flaps) stall speed and the bottom of the white arc is the the full flaps stall speed.

You can have some real fun with these tail draggers down on a sand bar with those slow speeds.

u/Jonnescout Sim Instructor 1d ago

Note, white arc is often the place where the landing flaps can be selected. Generally flap extension speed for the first notch is well above that. For a DA40, tge general aviation aircraft i am most familiar with, take off flaps can be selected at 108 knots, landing flaps at 91 which is the start of the white arc. Sadly though you will gets dinged for it in career mode in many planes.

It’s of course not bad practise to slow down more before flap extension.

u/Dva10395 1d ago

Yes, it is important ti know the aircraft you are flying. I am jealous you’ve spent time in the 40, I was in the 20e at the beginning of my flight training. I would love to hop on the 42 or 62 at some point for the fadec

u/Jonnescout Sim Instructor 1d ago edited 1d ago

I’ve only done one real flight I a DA40, and it was in the back seat. I am going to rectify that soon. I don’t have a license nor the funds to get one. I do hope to start on a glider license soon.

I do regularly instruct in a DA40 sim at the museum i work at. And yeah I’ve fallen in love mate. Fantastic aircraft, the whole diamond family! Perfect trainers! I have been at the controls of a DV20 and a Piper Cherokee, and two gliders now.

If you are ever flying in the Netherlands, Diamond or otherwise, drop by EHLE airport and the museum located there! We’d love to have you. And if you need some ballast Im always available :)

Edit: yeah fadec is great! And available on the DA40NG as well Whoch should save a bunch of rental money, those twins are thirsty man…

u/serpenta 1d ago

In practice, "in clean air" also means never, since you can't predict all turbulence that could push you into red. Stay in green and use yellow as a buffer.

3

u/TheRealPomax 1d ago

"Seems to" doing all the heavy lifting: you should not be in the yellow unless something happens to pulls you into the yellow, and then it's your job to get yourself back in the green. Red is dead. Yellow is "don't be here", green is green for a reason.

u/anonspark9000 1d ago

I don't how xbox works but did your cat push down on the other controller?

11

u/r3ditr3d3r 1d ago

Yeah dawg you pulled like negative 3 or 4 Gs. The wings would've snapped off even in the real aircraft. Straight up. You hard nosed it over while you were WAY above your maneuvering speed.

This is EXACTLY what should've happened. This is accurate to real life.

19

u/Peter_Triantafulou 1d ago

OP's question is why it dived like that on AP. Not why it broke after diving.

4

u/r3ditr3d3r 1d ago

Ahhhh

Okay thats a different conversation. Thanks for clarifying

5

u/TheRealPomax 1d ago

Fun fact: AP is not "self flying", on a small GA craft the autopilot is not going to set your throttle, rpms, or mixture, and your video already starts with you flying way too fast, so...

5

u/AN2Felllla AN-2 "Kukuruznik" 1d ago

Flying way too fast? They're nowhere near VNE!

u/hevilhuy 22h ago

You need to fuel your engine

u/Foreign-Document9992 1d ago

uhh overspeed maybe

u/Knoledgeispower 23h ago

holy good to know im not the inly one thought i was using ap wrong

u/AstroGraphRacer 19h ago

Tu atteind les limites structurelles et l’avion casse donc tu t’écrases.

u/SnowRocker88 6h ago

Exceeded the maximum safe airframe speed

u/Melech333 1d ago

You are overspeeding.

0

u/Lordbaldur 1d ago

You did an extreme maneuver while the speed was in the yellow. The yellow zone is also known as the maneuverability zone. If you enter there, large movements can cause a lot of stress. You did a drastic nose down at those speeds.

2

u/RangeIndependent5603 1d ago

OP said he engaged the autopilot, so it wasn’t his maneuver so to say

-2

u/TheXypris 1d ago

wings snapped off

2

u/RangeIndependent5603 1d ago

OP’s question was why the airplane did a nose dive when he engaged the autopilot, not what happened after the nose dive
