Learjet 3Issues using Octavi-IFR to set ALT-SEL since v1.1.8

Featured Replies

First thanks for this great airplane, which is developing better and better with every update. But since v1.1.8  i cannot preselect ALT with my Octavi-IFR. Within v1.1.7 there were no problems, even with other MSFS airplanes. All other settings (HDG, Frequencies, CRS...) work fine. What has happened?

Thanks for your help,
Markus

What control variables does the Octavi-IFR use for ALT PreSelect?

I do know the altitude alerter code was updated recently so clicking on the ALT SEL button toggles the update increment between 100 and 1000 ft.

Thanks for your answer, Al. Nor I can toogle increment between 100 and 1000 ft, which wood be very useful, neither the Octavi will work again. Until now I didn`t get an answer from the Octavi-Dev about the control variables. Please stay tuned👍

Suggest you make sure all is working correctly with just the mouse. Can you set the altitude alerter with the mouse? If not, try unplugging the Octavi-IFR (just a USB connection I assume), restart the sim and try again. If you can't get it working correctly with just the mouse, then you have a conflict somewhere. Make sure you are not using a third-partly livery, just test with a default Flysimware livery. And make sure whatever GPS you are using is up to date.

The Lear35 altitude alerter uses the Lvar variable  L:ALERTER_DIGITAL. This is a custom variable unique to the Flysimware Lear35.You have to write to this variable to set the altitude alerter; a default MSFS altitude alerter variable will not work. So you will have to program the Octavi-IFR to use the L:ALERTER_DIGITAL variable. I did a little research on the Octavi-IFR and apparently it works with Spad.Next, so that would be one way to modify the Octavi-IFR code to use the L:ALERTER_DIGITAL variable. The developer should be able to tell you the best way to make this change. 

Once you do that, however, I don't know if you will then be able to update the altitude setting on other planes that use the default variable for that. Maybe the Octavi-IFR can detect what plane is currently being used and use the appropriate variable -- a good question for the Octavi-IFR developer.

Hi Al, thanks a lot for your answer. The ALT-preselect works very fine with the mouse. And it already did work well with the Octavi-IFR until the last updates of Learjet 35.

Here is what Felix from Octavi answered about the variables:

Quote

What control variables does the Octavi-IFR use for ALT PreSelect? - The Octavi Plugin uses "AP_ALT_VAR_SET_ENGLISH", to set a new altitude preselect value. To read the currently set altitude, it is reading the "AUTOPILOT ALTITUDE LOCK VAR" variable.

Kind Regards
Felix von Plehwe, Octavi

I hope, this helps a little bit. 


Sincerly, Markus

Hi all,

Markus suggested that I chime in in this thread, which I'm happy to do. Let's get the Learjet working with our Octavi IFR-1 again!

He's using our plug-in, which is reading the above mentioned variables to read-modify-write the preselected altitude on every AP altitude input. It seems that that was compatible with how the Learjet worked internally up to the latest update. Was there any change to the variable used?

I'm not sure I understand what L:ALERTER_DIGITAL does - is that a boolean variable that toggles activates and deactivates the alt preselect, or does that actually contain the altitude in feet?

@Pidder - if the only way to set the altitude is to write to a custom variable, you might have to use MobiFlight or wait a few days/weeks until SPAD.neXt has integrated the IFR-1.

Hello Felix,

You have to set the Lvar L:ALERTER_DIGITAL to the value, in feet, that you want the altitude preselector set to.

Hi Al,

ok, understood, thanks! Seems like this was changed with the latest update, then? If that's the case, Markus will have to use MobiFlight. Is there an event we could trigger to increment/decrement the alt preselect in 100 ft steps? That way, Markus would only need to do a tiny modification to the profile.

At the moment i‘m on a short holiday but hope to check this later in this week.

So far thank you a lot for your help!

I am just a volunteer beta tester with Flysimware, and the only recent change involving the altitude tester that I know of is that now clicking on the ALT SEL button toggles the update increment between 100 and 1000 ft. I'm not aware of any way to set the altitude alerter without writing to L:ALERTER_DIGITAL. So to increment/decrement it in 100ft steps, you have to read L:ALERTER_DIGITAL, add or subtract 100 from that value, and write the new value back into L:ALERTER_DIGITAL
