GSX will not start fueling PMDG 738 in MSFS24

[r3volol]

I cannot get GSX to fuel the PMDG 738 at all in MSFS24. The fuel truck will show up, and I'll wait for GSX to tell me to set the fuel quantity. Once set, the fuel truck just sits there. I then eventually have to restart couatl in order to move on to passenger boarding. Is anyone else having this issue?

I tested it now, and I cannot replicate it, as you can see in the video, GSX is setting the planned fuel quantity in the right FMC at the right time, and the fuel truck counter starts as soon the quantity changes, see the video:

That is, if you use Simbrief, of course.

If you don't use Simbrief, so you are just inserting the quantity manually, it's up to you to be sure the quantity you are setting is HIGHER than the quantity you had before calling the GSX fuel truck, this is because the truck waits for a fuel increase to start.

That's why, when you use Simbrief and call GSX refueling, as part of the automation, GSX first set the fuel to 5%, call the Truck, and when the truck is in position, sets the final quantity according to the flightplan, so it will always an increase. But if you are not using Simbrief, it's up to you to do this.

I have attached a log if it can help - I have the same issue.
The automation does not always set fuel in the FMC and even when it does, there's no refueling happening.
This when using Simbrief, latest version of PMDG & GSX.

Yeah, my GSX is not doing any of then when the fuel truck is called. I do see a cutoff message at the top stating the aircraft variant isn't supported, but I can't see the full message. I'll try and get a video of what is happening for me in a day or two. Too busy with other stuff ATM.

You could check the log.

It's hilarious to me that you don't enable the logging by default, and I had to dig around the forums to figure out how to do that.

Anyways, I gave up trying to debug this garbage and did a full uninstall/reinstall of GSX and it's working now.

It's not obviously "hilarious". Keeping the full log always enabled would both fill your hard drive if you fly for a long time, and it also reduce performance because it logs quite a bit of stuff, so it must be enabled ONLY when troubleshooting something.

and I had to dig around the forums to figure out how to do that.

No, you don't have to "dig" anything: it's of course fully explained in the manual, page 39, the Troubleshooting Settings chapter.

Anyways, I gave up trying to debug this garbage and did a full uninstall/reinstall of GSX and it's working now.

Of course it's working, so much for that useless "garbage" comment, since if a reinstall fixed it, it clearly means the problem was on your side. The full installer fixes a couple of wrong non-default Compatibility settings that shouldn't be touched back to their correct default value.

Hello,

I have the same problem: GSX sets fuel to low in the FMC, fuel truck arrives, GSX sets fuel to the amount simbrief has calculated. Then GSX beeps at me that I have to set the fuel amount, in other words, GSX refueling does not start.

I have attached a log of it.
The log shows the whole process until the point right now, where GSX does not start fueling but beeps and says "please set the amount of fuel ..."

thank you very much!

[Guenseli]

When I change the fuel amount in the FMC myself then at one point GSX refueling starts. But I also have to enter that amount several times, fuel it up, empty it.

Maybe it is more about that GSX doesn't notice the fuel change amount?

[Guenseli]

BTW: maybe it would be a good idea to give the option to let start fueling anyway to overcome such problems?
And to make GSX more flexible in that regard.

An option could be sth like "start fueling anyway without input" or whatever you will call it.
That would mean, GSX fuel truck arrives as it currently does it now. And its waiting for user refueling for a certain amount of time (e.g. 30s or maybe this could be a user setting) and then, if no input (or change of fuel) is recognized, it starts refueling anyway.
it should have the amount from simbrief, if not, the refueling could be just for a certain time.

Your log shows you called the GSX fuel when you already had more fuel than required:

[00:00:26.266] Refueling called with fuel quantity higher than planned, adjusting to low level now

Of course, GSX recognize this "mistake", and it tries to fix it, and in fact it seems it did, by sending several keystrokes to the FMC, which should have set the level to 5%

[00:00:26.266] PMDG MENU
[00:00:26.266] MacroStep MENU
[00:00:26.266] PMDG FS Actions
[00:00:26.266] PMDG RSK 5
[00:00:26.266] MacroStep RSK5
[00:00:26.266] PMDG LSK 1
[00:00:26.266] MacroStep LSK1
[00:00:26.266] MacroStep -1000
[00:00:26.266] MacroStep KEY_5
[00:00:26.266] MacroStep -600
[00:00:26.266] PMDG LSK 2
[00:00:26.266] MacroStep LSK2

However, that's the only time when it does that. If the fuel quantity changed again (you, or the airplane EFB), it won't keep resetting it over and over, since it would mean constantly spamming the FMC with events just in case the fuel quantity changes again while the truck arrives.

Also, it would be helpful if you noticed if those key were accepted by the FMC. There might be situation when they aren't, for example if the scratchpad is not clear, and there's no way to clear it programmatically with the PMDG SDK, so you must pay attention to that.

I have payed attention to that, thats why I meant "GSX sets fuel to low in the FMC".

Yes, everything works as it should: fuel amount was to high (because I had let run (reset) that process several times before I started logging. ) and GSX acted as it should:
lowered the fuel amount, called the truck, then set the correct amount.
I also obsereved that all settings in the FMC where correct.

After that process, GSX started to beep and wasn't refueling

Read the edit you dolt, it's not working after a reinstall. Review the log. And it is worthless not to log by default. You can overwrite logs like literally every other program out there.

It worked once after a reinstall and now does not work again.

EDIT: And in your video, it shows resetting the fuel amount when the truck is called but that is not happening for me. Nor is it inputting anything in the FMC when the truck is called.

Enjoy your ban. Insulting is NOT accepted here. Learn to behave like a civil person, and your ban might be lifted, maybe.

Then as I've said, the fuel quantity must have changed again after GSX set it to low. I asked to check again the FMC to confirm the problem wasn't GSX not being able to set the quantity to low, the fmc not accepting commands or something like that. According to your report that wasn't the case, it can only means the fuel quantity didn't increase as expected.

Note that, I wasn't accurate enough in my previous description: if the fuel quantity is higher than required when the trucks arrives, it will go away immediately. Instead, if it's just there waiting, it means the fuel quantity is not increasing.

Yes, your suggestion to proceed anyway after some timeout is interesting, we'll look into that.
