C172: AP tries to kill me

I just had a flight in the Cirrus SR22. Autopilot was fine until I added the PROCedure. The keypad doesn't function at all. I attempted to input a VNAV altitude and pressing ENTER erases the entry, every time. Also, when the procedure was set active the waypoint flipped in reverse and the plane immediately attempted a turn. At that point I just disconnected the AP and hand flew her to base, There is a lot to be desired when it comes to the radios in this sim too. You can enter ATIS frequencies which do nothing until you use the pick list.

Proc right now is broken. You can't not to select  transition fix. Or select any approach fix by highlighting it and press Direct To to activate! The best way is to hand fly  for now..

I guess it makes sense that Asobo's autopilot team is the biggest internal team they have.

Straight and level flight with ap on, everything is great. Then out of nowhere, the plane banks heavily to the left with AP on. The AP announciator is on on the pfd. This is the 2nd time it happened to me today with just a couple of hours inbetween. Last time I had to pause the game while doing something and when I came back and unpaused it, the plane immidately went into a steep left bank and dive. 

 

update: Recycling the avionics seems to have helped. If I just turn the ap back on after recovering the plane, it just doesn't follow the FD. If I turn the avionic master switches off and on the ap behaves again. 

I have a theory on this as it's happened to me and I've avoided it since realizing something. There's a really BRAIN DEAD design choice where, if you have the mouse on ANY window other than the cockpit specifically.... for example, the ATC, the checklist, the VFR map, frankly ANYTHING then EVERY SINGLE CONTROL entry is BLOCKED and CACHED. The moment you move the mouse back to the cockpit every single thing you did with controls while the mouse was focused elsewhere gets sent instantly to the plane. For example, I did this on the ground today and when I went back to the cockpit the plane suddenly jumped free from the parking space and slammed into a house.

Have you or anybody been getting interrupted ATC calls? A hit of static and then you get, "Did you get my last transmission"? Maybe its supposed to be realistic? Not sure..... Asking for a friend..... LOL

Yes, you have to select offline audio in settings as opposed to Azure.

Same here with C172 G1000 system and autopilot. Out off a sudden it turns wildly into a spin towards the deck. I think this is a bug and has nothing to do with flying skills RL or simulated. Im afraid in depth systems are a bummer in this stage off the game. Flying online on IVAO or VATSIM with Microsoft Flight Simulator 2020 is not done (yet). The only type off flight you can file out there is VFR handflying.

As for RL: I dont think Garmin will be very pleased knowing their systems are only good enough to drill the aircraft into the planet after you turn the autopilot on.

Well, that's one variable I'd like to know. Is this experience limited to just the Garmin planes or all planes with AP? I had it happen tonight for the first time and it was also my first flight in a plane (the Beech B58) with that setup. If we knew this we could say it's not the AP, but he Garmin code, which i'm sure is complex. Anyone know? 

I also still wonder if this has anything to do withe the DESIGN choice of making all controls die when the mouse goes over another window. As an example, I nearly plowed into the ground on takeoff tonight due to the ATC wanting me to respond just as I lifted off and was trying to climb. The moment I went to acknowledge their message to change freqs, the sim stopped seeing that I was pulling back on the yoke and sent me hurtling back towards the runway so I had to jump back to control again. Sorry, but this one is just a really poorly-conceived choice by someone.

When will a 3rd Party GTN arrive.

I hate G1000s... the shimmer around these glass screens is awful as the antialising implementation is far from ideal (actually it's appalling) ......and I hate the GNS 530 even more.

Why are 90 percent of the stock GAs fitted with a G1000 ?

Even Carenado's first entry is recycling the stock G1000 .... I'm saying nothing but you all know I'm thinking ... 🥴🤔💔

Don't know if this will help any one else, as I'm a complete noob in this sort of sim, but....

I managed to get my autopilot to reset and correct itself after this just happened to me. (DA62)

I turned all the autopilot buttons (NAV, VS, etc.) to Off.  Then turned on the autopilot, and then engaged the NAV and VS modes and it was no longer trying to spiral to the right.

Same happens quite often to me. I thought it was just me because I cannot fly an actual plane, and missed some internal “secrets” of the ‘new’ fs2020 Garmin.

Apparently just a -rather serious- bug, then. I can usually ‘fix’ the sudden ‘spiralling to my demise’ by quickly disengaging the AP, setting the heading and altitude-hold again, and then engaging the AP again. 
 

Something really scwewwy goin’ on here, though. And, indeed, it’s almost always after about an hour of flying.

by the by, anyone noticed the strange trundling, or wiggling of the plane horizontally? It’s asif a somewhat slow servo is trying to correct a fast sideways drift, and is constantly being a little too late... Weird, that one.. It feels like the auto-rudder is a bit wonky. ( not have my pedals connected yet..)

The same thing just happened to me. And not for the first time. When the AP is engaged, the left roll and the AP directs me straight into the ground. I was never able to fix the autopilot in flight. I had to restart the game. Now it happened with the installed mod for G 1000, earlier it happened without this mod. At the same time, the autopilot behaves correctly most of the time.

It is a nasty autopilot bug, it is happening to many people, myself included..

Thankfully in light aircraft autopilots are superfluous.. just don't worry it and enjoy actual flying. I am sure in time they will straighten out these bugs.

I would expect all the default a/c autopilots, whether a basic 'stand alone' unit or one dressed up as a G1000, etc., use the same low level code routines. So that apparently is where that "nasty autopilot bug" is hiding.
