[FIXED 0002315] Reverse thrust does not work on the TCA airbus throttle

[ruccoa1]

Currently reverse thrust is no responding to my throttle inputs when moving the throttles past the idle gate. I don't believe this is an issue with how I have the plane set up at all, because using the default x-plane toggle reverse binding works correctly and the throttles lift the reverse levers. The TCA throttle uses an axis to control both throttle and reverse, the bottom 0-25% of the range is dedicated to the reverse range, and the top 25%-100% is the regular throttle range.

I haven't had an issue like this in any other plane with this exact throttle curve, so I believe the issue is how the challenger is not looking for the hardware throttle axis to register a reverse range, and is only looking for a button press.

 

I'm willing to sit down in voice chat if there is still some confusion of how I'm trying to do this, because it's kind of difficult to put this all into words. The airbus throttle style is meant to register full reverse when the axis is at 0%, unlike the boeing style where you pull the lever and push forward.

and this should behave the same way for any throttle axis that you check the "has beta/reverse" checkbox. if you compare how the plane's throttle responds when going from idle to reverse in this plane vs the toliss/ini/zibo planes you'll see the issue

Correct; I have the same issue with the same throttle. Unable to move past the beta/reverse detent.

Yes exactly the same problem, the reverser is not working with joystick axis. Unfortunately the TCA button on the reverses is also not working but this is a XPlane problem in the .joy file from the TCA Airbus throttle.

The button is not activ? Works in P3D ?

You can edit the joy file in Notepad. (Make a backup first!)

Yes I know, but did not have the the time to dig in to that!

I tried enabling the "has beta detent" option in the joystick settings of my quadrant, and its not working properly.

Same for me, reverse is not working with TCA thrust levers…

It‘s a pity, since it works on most aircraft I own.

[Ahmed Saleh]

Same here for the TQ6+. Must toggle reverse thrust otherwise does not work.

I’ll be honest with you all, I always considered this curve modifier as only applicable to prop planes, I never thought to use it for jets. Hence, I have no idea what it actually does behind the scenes.

Are you saying that every addon you own has custom support for the TCA? Because I only know of the FlightFactor and ToLiss Airbuses that do.

So, if you want this supported in the CL-650, it would help if you can describe to me what exactly needs to change in the addon?

thanks.

[ruccoa1]

I doubt that the addons all have custom support. I'm guessing that when thrust is idle and x-plane starts sending reverse thrust axis inputs, the addons are able to interpret that as enabling reverse thrust and matching that value.

[ruccoa1]

Looking at some of the cockpit data output stuff, it looks like there is a value for "engine feather, beta, reverse thrust" that it can display. Loaded into the zibo to test it out. if thrust is forward this value is one, if I move the throttle to reverse it changes to 3. when I then move the axis all the way to max reverse, the throttle (actual) command increases. so all toto should need to do is watch for this engine feather beta reverse dataref to be set to 3, and then when this is the case, command reverse thrust as the throttle axis increases.

Is this discussion not being overcomplicated? The TCA throttle has a reverse range protected by levers, and the protected part can be indicated as part of the reverse range in the response curve. Standard x-plane function. Every addon can work with this, so should be no reason this very complex and advanced addon cannot..

I'm sure that's because most addons are using default systems so get this "for free". I imagine the developer just didn't consider someone using a setting that seems made for turboprops not jets (it has "beta" in the name, and forces you to have a beta range in the curve, even if it's tooltip mentions jets, no-one looks at tooltips, including me until now...). But if I can figure out how it works then I can request support. No promises.

As such, how did you get the second column of numbers to change? Every time I do it resets to 0.17, 0.33, etc. Don't worry, I figured it out and it's messed up, stupid X-Plane. But I still can't figure out how this is meant to work on the backend.

Of course it can but it's going to take custom support because this addon isn't using any default LR systems unlike every other addon in X-Plane.

Thanks. I think there’s a piece of the puzzle missing because I set up this curve like yours, tested it in the default 737 while watching datarefs you mentioned and it worked, however the same dataref changes didn’t happen in the 650. Hopefully there’s some obvious switch in Plane Maker that they can find.

Good news! This has been implemented and should be in the next update. Watch here for confirmation upon release.
