MSFS A320 Autothrottle

Flight Simulator 2020

Is anyone else having issues with the auto throttle in the a320? I am trying to do the paro landing challenge and the throttle is automatically going from idle to full on final. I have it disengaged in the cockpit. This only happens when I am set up for a perfect landing as well. It’s becoming very frustrating.

I’ve had the same exact problem with the airbus. Only on a perfect line up and landing. As soon as I get to 50ish feet the auto throttle kicks in and goes to full. Even with autopilot off and me manually turning auto throttle off it kicks itself back on. Very frustrating. Think it might be a game mechanic flaw.

Got it to land today without the throttle kicking in. Not sure why. But fuck I’m getting tired of these random crashes to desktop.

What is your airspeed on final? Is it going into A.FLOOR?

Just tried several times to maintain a fixed airspeed. I was at 140 just to try and it still happened. The reason I’m not convinced it’s the normal airbus auto thrust and just a bug is because sometimes only one engine goes full.

Also no, it’s not a.floor; I wish. I took it there on purpose and it didn’t even engage half the time.

Yes mine went to Afloor and Im getting this issue , whats going on cap?

A floor is where airbus automatic stall protection kicks in, it will full throttle to recover you. This means your coming in too slow on approach if it’s happening to you

Where are your throttles at this point?

Airbus manual throttle is engaged only below the detents.

It happens anywhere in the range, but the last three times I have had the throttle at idle and been 50 feet above the runway and the auto throttle has engaged full. Sometimes it will only engage one engine as well. It's maddening.

You should be retarding the throttles to idle around 50-30ft in the NEO. Haven't tried the 320 yet in sim though so not sure if the behaviour is accurate to the actual airplane.

2
pivotcreatureOP•

That’s exactly where I am retarding the throttles. I’m wondering if it’s something wrong with the game, because sometimes only one engine goes full thrust. But even with an airbus normal auto thrust, it shouldn’t do anything if the levers are at idle right?

1
plhought•

Should be idle yeah. Maybe Asobo ballsed-up the alpha-floor protection (basically full thrust if aircraft is approaching stall) and it's incorrectly applying full thrust in the flare?

2
pivotcreatureOP•

That’s what I’m thinking but it doesn’t always apply at that speed.

Have you figured this out? It's happening to me too at 140 or higher, and I'm about to ditch this plane until I figure out what's going on...

I'm completely new to this genre, and I'm having this problem, too. BUT I did figure out that if you hit "Shift + R" when you're going in for a landing it seems to stop this from happening. I was also having an issue where, when taxiing, it would automatically max out the throttle and send me out of control. I tried playing around with "Shift + R" and "Ctr + Shift + R" and have found that "Shift + R" Enables/Disables it and "Ctr + Shift + R" toggles the actual throttle maxout.

Of course I have no idea what I'm doing, so this may be obvious to some, but it works for me.

I'm having the exact same issue, but I have done a lot of flights in the A320 with no issues so I think this challenge is just bugged. Which sucks because it's the only one I cant complete.

I was able to get it to work by applying full speed brake and coming in at idle on a steeper slope. That kept it from automatically kicking on. I mean, I only got 3k points but a check mark nonetheless.

I've been having this problem after exiting slew mode.

I'm having this exact same issue. Every time I'm lined up for a great landing, right as I cross the threshold auto-throttle kicks in and boosts me back up for a go-around and usually I can't get my mouse over to cut off the A/T quick enough. I'll try the SHIFT+R thing but I actually have no idea what I'm doing so I figured maybe I just had to click something else off on the autopilot.

I also can't figure out why the 320 keeps sending my trim up and down to max with no discernible target. I took a flight yesterday and got it up to 10k, leveled off, and just watched the trim move itself all over the place while I porpoised up and down 3k feet at a time.

1
pivotcreatureOP•

So the trim is part of how the a320s flight computer works. That much I know, what speed are you going when you cross the threshold? Does it say “a floor” on the top left of your PFS?

1
gooselee123•

TBH I don't remember so I'd have to try again and look. I want to say 160kts or so? I did not notice an "A floor" indication but I may have simply missed it.

The airliners are more of a fun messing around aspect to me right now. Working to get really good at the basics in the 172 as I have a goal to finish my PPL and have at least part ownership of one by my 45th birthday. :)

This is always happening to me. I’m about to flare on a perfect approach and goes full throttle and messes up my approach. Even if I disconnect A/T and the Auto Pilot. Any solutions?

1
pivotcreatureOP•

If this is happening outside of this landing challenge you’re probably activating alpha floor protection. I think it’s a bug with landing challenge tbh. I flew the approach not on the challenge and it worked fine :/

I'm going to echo the same comments. I'm giving up on the a320 for now in this game because it's maddening. I had a perfect landing set up 4 times and each time the auto throttle would turn itself back on and ramp up to full power right as I crossed the runway threshold. Last time I just gave up and nosedived it into the ground. This was after an otherwise uneventful, reasonably long flight. Very frustrating to have the plane/game fight you right at the end and feel like you wasted all that flight time.

1
pivotcreatureOP•

What speed are you coming into the approach at?

jeff92k7•

I'd have to try it again to check. I'm just tired of that plane fighting me constantly so I went back to some other planes since that unfavorable experience earlier.

I can say that I was on a good (to me) glide slope coming in with little throttle and then killing the throttle shortly before the threshold. I'm aiming, and on target, to touch down between the touchdown markings and the aiming point markings.

I tried a higher angle slope earlier, based off other comments and just ended up bouncing because the planes nose wouldn't come up fast enough to soften it. One time, the game froze mid bounce and then kicked me to the screen saying I damaged the plane. sigh.

I'm sure it's my inexperience more than anything, but it just seemed really odd that the plane would kick in full throttle against pilot wishes and force you to completely miss a good landing multiple times in a row. After going back to smaller turboprops, it was like a sigh of relief to have a plane that does what I tell it, making the flights so easy, instead of the A320 fighting me and changing settings on me constantly (throttles, trim, etc.)

I'm sure that's way more than you wanted and didn't really answer the question so I'll have to try again and get you an answer.

So tried it again, over and over and over and couldn't duplicate the same issue.

I slewed back off the runway about 10-12 times and couldn't get it into a situation again where it shot the throttle up to 100%+ and held it there. Closest I could get was when I get below 125 knots, the throttle would automatically spin up a bit and then settle back.

I tried repeatedly too low and fast, low and slow, high and slow and high and fast. I even nearly stalled it into the ground and couldn't get it to slam the throttle the same way again. Earlier, it would ramp up to full throttle and hold it there so I couldn't do anything until I was well off the far end of the runway and climbing. I guess it may have been a bug in the game for that flight I was doing earlier.

Just tried Shift + R. It stops auto throttle for the moment. But the very next second, auto throttle goes to max. you keep keep pressing shift R. very annoying. Need a more permanent fix.

Same issue here. Throttles weren't spooling all the way down even when i set them to idle. Then got 20 feet from touchdown and they went to 100% on their own. I might just stick to the cub. Then the 747 throttles get atuck at 100% immediately after take off! Makes it a very frustrating time!

So I had to dig out a very dusty A320 manual from the internet to find this out (having the same issue) and I think I have a fix.

There are auto throttle disconnect buttons on the throttle yokes themselves. Little red button where your thumb would normally be.

Press and hold this button for 15 seconds. It will disable auto throttle for the rest of the flight. Only a full power down and power back up will give you auto throttle back.

Otherwise, there’s no way to prevent the a320 from engaging the auto throttle when a) you floor it, and b) the plane detects near stall (which is engaging it during your landing attempts).

I also think the plane is working as designed and maybe we’re all just bad pilots. This used to happen on FSX and I think it happens in X-Plane as well.

When the ATHR goes to full thrust before landing it’s because it detects near stall; maybe real life airline pilots would never allow this to happen and our landing procedures should be better even when we think we’re doing a pretty good job.

I hope this helps!

I am having issues too, the A/THR engages by itself, the throttles advance alone, asymmetrical at times, no way to manage the speed, manually or not. I have the Warthog.

Same issue here. I'm completely new to this genre as well but I figured this shouldn't happen. I'm currently learning ILS approaches and just turn A/THR off as soon as I capture the glideslope. My airspeed shoots up as soon as I do but at least the 320 stays on G/S.
