Hi,

I'm looking for a couple of parameters that I can't seem to find in the configurator; perhaps they do not exist yet.

First I'm looking for the AP source select for GA aircraft, which looks like this in the X-Plane C172.  I'm looking for the control so that I can assign a toggle switch, and for indicators so that I can display NAV or GPS in my panel.

The second item is related to fuel.  I've assigned a 3-way switch to the Fuel_Sel_Tank parameter (Left-BOTH-Right) on my panel.  I would like use 3 LEDs to indicate which tank is selected (left, right or both), however I cannot find an indicator for this.

Does anyone know if these parameters exist?

  Thanks

Mike,

1) Open the database table in the configurator: "Nav Instruments" -- > select "HSI/RMI"
Find the "HSI source Switch"  or " HSI source to display"  (you need the second one)

2) Usually, the fuel selector doesn't have indication (I didn't see at least).
Do you really need this?  The valve handle shows the position itself.

Hi Vlad,

Thanks!  HSI_Src_GPS worked great; I considered this parameter, but never tried it since I don't have a HSI.

Regarding the fuel tank indicator, you are correct the handle is the only indicator.  I'm flying the default C172 with X-Plane.  I'm looking for an indicator because I'm building a cockpit with forward only visuals, so the virtual handle won't be visible.  I could simply use the position of the toggle switch, but the throw on the 3-way switch is so slight that it's tough to see.  I'd prefer to put an indicator near the switch for feed back of the change.

  Thanks

Mike,

Of course, SimVim system is intended to be used for building a full "hardware" cockpit,  with X-Plane only displaying the forward view (and other external views).

First, take a look  at the bottom of this page where I show an example of how a 3-position Fuel selector switch can be made using 2 toggle switches and an anchor mechanism.

If you need you can use these recommendations about how you can implement the position indicators in a simple way: http://simvim.com/tips_sw_led.html

Hi Vlad,

Thanks for the suggestions.  I'm not building a replica cockpit, like I would imagine most of your other users are. I'm building a much smaller desktop version and I'm trying to keep my controls and indicators fairly compact.

I've looked at your page on indicator and switches in the past, but I designed my indicators to connect to a MAX7219 driver.  My thinking was that I would have more options to control the indicators through software if I connected the indicator to a LED driver.  If there isn't an indicator for this and one can't be added, I'll have to look for another option.

  Thanks

Mike,

Those LEDs, which show the current status of various aircraft systems, must receive data from the simulator, connect to the master board / drivers and must be assigned as parameters in the configuration (using appropriate datarefs).

But, for those LEDs that are designed solely to indicate the position of the switch, you do not need to use valuable digital outputs, just use some spare contacts on your switch (as in the case of the korry type) or use the connection options described on my page above.

Hi Vlad,

I guess I see it a little differently than you do.  I see the value in being able to reassign the indicator from software, instead of the LED being hardwired to a switch.  That way my configuration can change to suit what aircraft I'm flying.  Thanks to your support of multiplexers and LED drivers, I have access to more digital I/O then I could possibly use, so I'm not worried about running out of outputs.

Regardless, thank you very much for the support and this great piece of software.  

  Thanks
