X-Plane TQ6 GF-THR 737 Handles

Hi there,

On the TQ6 pane I can see the checkbox for the GF-THR 737 Handles, but it is not able to be selected.

Is this not implemented, or am I just doing something really wrong?

Comments

    That function simply swaps the buttons on the TQ6. There were some instances where people were stating using the Handles upgrade from GoFlight swapped the buttons.

    I'm not sure if this feature is still relevant. If you need it, I can add it to the dev plan for a new release this week.

    Best wishes

    Well, from what I can tell, the 737 reverse thrusts are not an axis but just a button when in full up position.

    This makes it a little complicated since X-Plane is a bit limiting for this situation. X-Plane gives a full reverse thrust toggle button command, but this is of course assuming you press a button once for on, and again for off. In the sense of the throttle unit this is not really possible. Perhaps it would be good to assign this command to the reverser handles with a custom bit of code attached to the full reverser toggle command in X-Plane, but as soon as the reverse handles are considered "off" then release the command?
  • admin_ppsadmin_pps

    The reverse thrust levers are actually buttons on the TQ6, so you can just assign an X-Plane command for the ON button event and another for the OFF button event which should work just fine in your situation or am I missing something?

    I think you're missing something...

    The command option for reverse thrust that would work with this system is the command for reverser full thrust toggle.

    The problem with that is X-Plane assumes you will press a button to activate it, and press the button again to de-activate it.

    The 737 throttles are not axis, they are buttons for reversers, and are read as:

    1. Pull reversers back = button held on

    2. Push reversers back down = button has been let go

    This means X-Plane sees the button "pressed" but never pressed again to turn it off when you retract reversers, thus code needs to be mode to fire that command as basically a "hold" button situation.
  • admin_ppsadmin_pps

    You can set Commands for the buttons when they are ON, OFF and being held (HOLD) by simply clicking the drop down box and changing ON to OFF or HOLD. So you can configure up to 3 different Commands on a single button.

    Steve,

    Are you talking about in GIT, or in X-Plane? Perhaps my memory is lapsing me, or I've just programmed things to solve my issues for so long I've forgotten how powerful default X-Plane can be?

    If you're speaking about GIT, then I'm not sure...

    When I go to my TQ6 page in GIT it shows options for 4 buttons. The TQ6 ADV technically has 6 buttons if you include the revers levers.
  • admin_ppsadmin_pps

    No, I'm talking about GIT. Ok, I understand the confusion.

    There are actually only 4 buttons on the TQ6. The two AT/Disengage buttons are mapped to the same button and the ATO&GO buttons are also mapped to the same button. So along with 2 reverse buttons there are only 4 programmable buttons.

    Goflight have wired the buttons up this way, it is nothing peculiar to GIT.

    Best wishes

    Cameron , in GIT the ON OFF and HOLD don't necessarily mean that is what happens with what you are manipulating, they are just events to send a dataref or execute a command. 

    The ON would send the "command" full reverser toggle , and the off would send the same thing. That would toggle it on when you hit the on position of the switch and toggle it again and make if go off as you released the throttle from reverse. That would work perfectly.

     Where you are getting confused is that when you use those "commands" (stuff that you can setup directly in the x-plane controls section), those are not datarefs .  A "command" is the same thing a making a custom bespoke event in GIT  except it's already done for you. It's like a pre built macro.

    If there were a dataref named full reverse thrust that took a 1 to fire it and a 0 to turn it off you would have to make 2 bespoke events, 1 to set fullreversethrust= 1 and one for  fullreversethrust=0 , then assign them to the on and off positions

    Another good example is on the IXEG 737, there are LNAV and VNAV button commands already made by IXEG so all I had to do for the profile was set their command to the ON position of a button on the MCP because every time you send that command it toggles from on to off and vice versa.

    Ok guys, I full well understand what datarefs and commands are.

    Perhaps I am not communicating myself properly, so I'll try again.

    With the left side reverse lever as a test, I have created a bespoke for it. Keep in mind, the left side lever is viewed as a button by X-Plane and GIT.

    When I move the lever, it does EXACTLY what I told it to do. The reverse thrust comes on full tilt. This is unfortunately where the fun stops. As soon as you put the reverse "button" back in the off position, the reverse still remains full tilt because GIT is not seeing a second button push to de-activate the command it just activated. To get the sim to turn off the reverse I again have to move the reverse back to the up position to simulate yet another button push. It then shuts itself off.

    I have tried HOLD/ON/OFF. The reaction is the same each and every time. I hate to be asking all these questions, but the reality is documentation for this is not grand, so it's possible I'm doing something wrong, I just don't know what. For now I view it as a limitation until I'm told otherwise.

    What I need is for GIT to "do this bespoke event until I let go of the button". I would expect HOLD to do this, but apparently it just doesn't.

    Look, a really simple test for you to see what I mean. This is much more similfied than the bespoke I wrote, but it gets my point across.

    1. Create a bespoke with the title IXEG_Reverser_Logic

    2. Send sim/engines/thrust_reverse_toggle command

    3. Assign this bespoke event to the button of your choice. You need to press the button twice to activate and de-activate thrust reverse! Since the reverse axis on the GoFlight TQ6 ADV module is perceived as a button, this means you have to move the axis up/down/up/down to simulate one cylce of revers thrust on and off.
  • admin_ppsadmin_pps

    I have just tried using the sim/engines/thrust_reverse_toggle Command on the default 747. The trick with the TQ6 reversers is that you are holding the button during the reverse so the OFF event never fires on the button, but the HOLD event will when you release the button.

    So I assigned the sim/engines/thrust_reverse_toggle Command to the ON Button Event as well as to the HOLD Button Event and the reverser works great.

    Hope that helps!

    Best wishes

    Sorry Cameron I hope you don't think I was talking down to you. It's hard to tell from a few posts a person's knowledge of the inner workings of the sim.

    Sometimes the logic you have to do to make some datarefs or commands work isn't , well, logical.  :P

    Sometimes you have to go through the problem, sometimes you have to go around the problem with different way and this is one of those cases.

    You can always fire up DRT too and try to see what datarefs the reverse command is firing and manipulate those directly too, it just takes more time :)

    Hello,
    (sorry for my English)
    I will refresh the topic ....
    Applies to: X-Plane and TQ6.
    What do you need to do to ensure that Thrust Reverse does not switch on when the throttle is set to its maximum?
    (probably it is possible with the help of Lua).
    When I used FS I used FSUIPC and there was a way that Thrust Reverse would not turn on when the throttle was above the lower position.
    Once again, I apologize for my English and I am asking for help.
  • admin_ppsadmin_pps
    I have had a quick look at the datarefs.txt file in the plugins directory and this showed up:

    sim/flightmodel/engine/ENGN_thro_use float[8] y ratio Throttle (per engine) when overridden by you, plus with thrust

    You could write a Bespoke Event or Lua and assign it to the buttons that checks the value of this array of engines and if its above a certain value, the rev thrust command would not be sent, otherwise it would be sent.

    Best wishes
    Steve
  • BulvaBulva
    :-) Thank you very much. Only I do not know if I can deal with it myself .
    In the Download section, there is a configuration for TQ-6, but without checks of the value of array of engines.
  • admin_ppsadmin_pps
    You just need a Lua if statement to read the dataref and it its true send the rev thrust command.

    Best wishes
    Steve
  • BulvaBulva
    ... well OK, I can do that the reverse thrust does not turn on at the maximum throttle setting (and only at the lower position-this is OK). But what to do to reverse the reverse thrust after releasing the button when the throttle is in the upper position and goes back down ???
  • admin_ppsadmin_pps
    The reverse thrust command is a toggle so just send it again e.g. sim/engines/thrust_reverse_toggle_1

    Best wishes
