Just tested the custom FBW system. It's great. A huge step forward. Finally, this thing flies like an Airbus. Especially the flare mode is now much more accurate. You can feel how the plane wants to drop the nose and you have to apply back pressure on the stick to keep the nose up. Very nice. Give the FBW guys 6-12 months and this thing is going to be study level.

So, we now have two parallel A32NX files?

Yes. There is the "standard" version of the FBW mod without the custom fly-by-wire system and there is the one that includes the custom fly-by-wire system. Bit confusing. Hopefully, they will integrate the custom fly-by-wire in the "standard" version soon.

The custom fly-by-wire is definitely a game changer. I hated landings with the "standard" Asobo based controls and now I can't stop doing touch-and-goes with the new system.

So far I couldn't get reverse thrust to work with the custom fly by wire version, works fine in the "standard FBW version, though.

Yeah I hope so, they mentioned that flight director issue is blocking merging this into the master branch. After flying with this for a week, honestly is very hard to go back to the default fly by wire system, that one is sh**t as it gets 😄. 

Lovely bird to fly now with the latest dev version..

I just tried this.. The windshield wiper is permanently on at low altitude. anyone noticed that? I can't shut it off.. It's a minor thing.

Strange, mine isnt .

Mine neither

What are the exact features of this FBW mod? Is it this "stick deflection = G loading" capability of the real Airbus? Capabilities as described in the following document:

http://flightzoomer.com/downloads/Flybywire-English.pdf ?

Sorry for asking this basic question, but I was not able to find out before.

If that would be the case, you could pull the stick fully for any time and get consistently the fastest possible climb out. After moving the stick to the side, you would get a roll rate proportional to the stick deflection. Bringing the stick to neutral and not moving it ever again would mean, that the vertical G loading (in essence the current Flight Path Angle) would be kept constant all while the turn at the reached bank angle would continue eternally.

You mean the pitch protection? Is not yet implemented as being written here:

Not solved or missing
❌ pitch normal law (C* law) creates a too small pitch rate on low speed or g-load on higher speeds
❌ High speed protection
❌ High angle of attack (AoA) protection
❌ alternative law
❌ direct law (in flight)
❌ simulation of hydraulic system missing -> when engines are off / electric pump is off control surfaces should not work

No, not the pitch protection. The normal flying with the stick where "Stick neutral = 1 G flight = unaccelerated flight vector". It would be nice, if the requirements met (= capability) by the fbw implementation would be described a bit somewhere.

I have looked in code, it looks extremely comprehensive, but still the exact capability is not evident.

I ask because I have programmed a gauge many years ago (for FS2002) which realized this G-Load pitch controller (with much simpler code). The paradigm is totally different than normal aircraft are flown, because no manual trimming is ever required anymore. Simply bringing the stick to the center position means the aircraft keeps the flight vector no matter what. For this reason the Airbus stick is simply spring loaded and force feedback is not available (it would even be counterproductive).

Some things more, that follow from this approach:

- Assume the stick is kept centered and the aircraft climbs with a particular climb rate, if now the thrust is increased, as speed increases, vertical speed is automatically increased as well in order to maintain 1G. Basically FPA needs to be kept constant.

- Assume level flight, if the stick is deflected to the side, a turn begins while the system maintains level flight no matter what (in order to maintain 1G on the pitch axis)

More cases and details can be looked up in the linked PDF....

Ahh I see, then I'd highly recommend you to login to their #fbw channel in Discord and have a chat there with @AGuther and the other guys who are working on the fly by wire system, I think would be helpful

My first posting in the forum, nice to be here 🙂

And yes, i suffer the same problem with the A32NX developer version. Together with batteries initiation from cold and dark, the windshield wiper comes alive?? Somewhere after takeoff they shut down. Funny, in the developer version both wiper switches are inactiv.

Not so in the stable version, where wiperswitches works well and wipers operates as they should.
