Fenix landing problem

Yes, I know, if you want to land with flap 3, you have to press it in the overhead panel, otherwise an error message will appear in ECAM.

I'll try a Flap 3 load and see how the machine behaves

 

 My guess is you are running some 3rd Party Program at the same time that is messing with the airplane. In the first video I hear callouts that are not default.

You should try to disable ALL add on programs aside from scenery to test this.

There is also no real help in Fenix's Discord channel and I have now created a ticket with Fenix.

A dev responded to your questions directly in Discord, with some questions and suggestions. If you do not reply to them, I would expect you find limited help.

Ein Entwickler hat direkt in Discord auf Ihre Fragen mit einigen Fragen und Vorschlägen geantwortet. Wenn Sie nicht darauf antworten, gehe ich davon aus, dass Sie nur begrenzte Hilfe erhalten.

Where ? Maybe I overlooked that?

The problem with Discord is that many posts make it a bit confusing.

I am thankful for every help

It's really hard to see in your videos because your 4K wide-screen is so large that the video is tiny on my little 16 inch screen, but it looks like you had your speed set to 131 knots in this video, here, which you can see is actually below Vs0 (Flaps full stall speed) in straight and level, which is shown as 140 knots right after you level off in Alpha Protection.

You might fix this by having higher VREF numbers? Just take whatever stall speed you're getting and multiply it by 1.20, and set that as your final approach speed.

There's nothing less important than the runway behind you and the altitude above you.
It's better to be on the ground wishing you were in the air, than in the air wishing you were on the ground.

The Airbus is calculating all that on its own.

It knows how heavy it is, it knows the winds and temperature. It even calculates higher VREF speeds on the fly if gusts are present. So something is really off here. And it has nothing to do with the Fenix, it HAS to be something that is interfering.

He says he knows how to operate an Airbus (which I'd take with a grain of salt, considering that he doesn't understand its protections and tries to fight against them), so I'll just assume that he knows how to program the MCDU properly with the data it needs.

First step to troubleshoot is always to run the sim without any addons, so with an empty community folder (except for the Fenix) and no other app running alongside the sim. Did you do that?

I agree that there's something very wrong with the numbers. He's obviously trying to maintain an approach speed below flaps extended stall speed; That's why alpha protection keeps kicking in and why he's unstable the entire way down. If he's using the right speeds from the EFB and MCDU then the only other alternative is that something is off environmentally; though I can't read the temps and I don't know the DA on this approach.

And that's the odd thing. In the video everything seems to be fine until he goes Flaps Full. Then suddenly the stall speed increases above VAPP. This shouldn't happen.

And it certainly never happened to me in all of my years of simulated Airbus flying, and most definately never happend with all my approaches in the Fenix.

My money remains on an external app interfering.

Yeah, I just watched his 3rd video where he lands at KLAS with flaps 3 and doesn't have any issues with the speed tape shooting up.

The weird thing is that this is a clean install of MSFS and Fenix. From novice eyes like mine it remotely reminds me of the flaps 3 bug we had a few months (year??) ago, but that affected everyone and not just one user.

I think at this point he'd do best to post a discord Community Forum thread so that he gets more concise responses from the team (I.E. Dave2) where he doesn't have to fish through a sea of messages in fenix-chat.

Yes, the stall speed indication increasing is weird. The only situations I can imagine where this is supposed to happen is a high G-Load, extending the spoilers or with severe icing.

The other thing is that the autothrust does not increase thrust when the speed is getting close to the assigned speed. It stays in Idle until the Alpha Protection kicks in - as if the thrust levers are not in the Climb but in Idle position.

So something completely screws up the Fenix here. I have never seen anything like that in hundreds of flights with the Fenix.

The OP needs to rule out any other third party app influencing the flight model and logic of the Fenix.

Hi,

I'm glad you can see that something is wrong.

Yes, after reinstalling I only had Fenix installed. Community Order was empty.

I have about 3000 hours at Boeing and about 500 hours at Airbus..

I wouldn't say that I'm a professional and know everything.

But I've never had such problems with Airbus and I don't know what I would have to do if such an error happened shortly before landing. What did I forget or do wrong?

I now tried a flap 3 landing and also had problems. I briefly tried to make flaps full and when it pulled up, I went down to 3, but the landing was still problematic
