PMDG JetStream 4100 (JS41/J41) Saitek Multi-Panel Lua

[pilotjohn]

EDIT: Latest version (1.2.1) attached as of 12/6/2011

Here's a Lua script that makes the Saitek Multi-Panel via SPAD (default config) work with the JS41. Some minor inconveniences/notes:

1. HDG light may come one when HDG is not ON on the panel (AP ON and no LNAV selected, or sometimes when VS selected)

2. ALT light comes on when VS or IAS is selected whether ALT/ALTSEL is ON on the panel or not

3. ALT switch toggles ALTSEL mode not ALT

4. If no mode is selected when AP turned ON, heading may drift

5. Eliminates a bug in the AP where switching from IAS to VS sets VS to -9900 FPM

Here's an update... it fixes the J41's A/P from selecting +/-100FPM VS when new ALT is selected while ALT HLD is engaged (thus causing the plane to leave the captured altitude).

Also, a mention in the instructions that you need UseProfiles=No and the name after Auto should be Jetstream not JetStream.

Rename .txt to .lua.

anyone ?

anyone ?

What's not working for you? If the altitude preselector works, everything else should be working. Some of the lights will not synchronize but there's no way to fix that. Are using SPAD? I've only tested it with SPAD.

[renswillink]

as soon as i activate the AP the heading bug jumps and nothing really works anymore ...then when i disconnect the AP the heading bug stays on the current heading and follows if i steer it is inpossible to change it anymore

[pilotjohn]

Are you using SPAD?

Do you have your modes preselected before engaging AP?

What happens if you select HDG mode?

I'll try to duplicate, but the only time I've seen this is when A/P is turned on without any mode being selected, or in GA/GA mode. In that case it's an unfortunate rounding issue.

[renswillink]

Yes im using spad

i do preselect my modes and then engage the autopilot ....everything works fine ecept the heading as soon as i select heading i can change it with the dial after i engage the AP the heading bug jumps to the heading seen on the mip

Just so I understanding...

You preselect HDG mode, and select a heading of XXX using the Saitek panel (with XXX displayed on both the Saitek and EHSI). Then, when you engage the A/P the heading selection to changes to YYY (the current actual heading)?

[fmweasel]

pilotjohn, you're amazing, I am using your file to huge success.

Still tweaking things to get around a few personal quirks but I'm enjoying it a great deal. Thank you very much

[pilotjohn]

Attached is an update to the JS41 Saitek Multi-Panel Script.

There might other fixes I haven't posted here yet, but most importantly it changes the AP button functionality to turn OFF the yaw damper if it's ON but AP is OFF.

As it was, when the AP was toggled OFF the YD stayed ON (default JS41 behavior), and needed to be clicked OFF with the mouse at 200 feet AGL for landing (otherwise you'd have a nasty cross-wind touchdown). This was rather disorienting to say the least.

Thus, the new order of functionality for the AP master switch is as follows:

AP ON YD ON

AP OFF YD ON

AP OFF YD OFF

...

So when passing 500 feet AGL, AP can come OFF with YD remaining ON, and then a second press at 200 feet AGL will turn the YD OFF. On a go-around a third press will bring both AP and YD ON.

As before, change the extension to lua.

Hi , sorry but i'm new to this. Can you tell me how to use this lua file to work my multi panel on the jetstream?

[DanW]

Hi John,

Thanks for the script.

I'm also finding the heading bug can't be moved, unless HDG mode is turned on first. This is not like the default aircraft, normally you can bug the hdg in advance.

If HDG mode is off, when I move the HDG around, it jumps back to where it was before I moved, about 1 second later.

Any ideas on what causes this or what we can change in the script?

many thanks

I've not seen this behavior. The only odd thing I've seen is that the heading bug continually syncs to your current heading as your manuever.

It sounds like it might be related to that, but I haven't been able to pinpoint what causes the behavior.

This is really a band-aid for something that PMDG should have fixed (and clearly could have if a script can), but there's no chance of that.

It relies on so many kludges that I'm surprised it works as well as it does.

Hi , sorry but i'm new to this. Can you tell me how to use this lua file to work my multi panel on the jetstream?

If you follow the steps in the first few posts it should just works.

Google SPAD FSX, and install it, while uninstalling (or at least disabling the Saitek clients in exe.xml).

[DanW]

Hi John,

I managed to get around the heading reset by overriding the heading movement as a button, then using a lua script to incr/decr heading found here: http://spad.189988.n3.nabble.com/PMDG-Jetstream-4100-AP-ALT-Display-on-Multipanel-tp4024982p4025041.html

I can now set heading before switching the HDG mode on, although it won't show in the panel until I press heading, I can see the bug in the VC.

I have only tested on the ground so far, as I'm multi-panel enabling all my planes first before I fly again.

Does anyone know how to contact @pilotjohn out of the forum?
 
I tried send email to "pilotjohn at gearsdown.com" and I have not received answers. Also private message.
 

Google SPAD FSX, and install it, while uninstalling (or at least disabling the Saitek clients in exe.xml).

 
Where is the exe.xml?
 
Are there a sample INI updated for today?
 
Which logs are important? How to view them?
 
I am cousin of FRANCISCO MARCONI and I am trying help him. I also wish, if allowed, of republish the codes as a project in git. If possible, under an open source license.

 

Which would be the steps to install JS41SaitekMP.lua from scratch?
