Brakes not working in MSFS 2024

Martyn

Can you confirm that you are all using MSFS 2024, and there's no difference after switching on the electric hydraulic pumps?

4th flight in MSFS2024, Brakes and P-Brakes normal ops ... FYI

Woolies

Yes, MSFS24. All systems are nominal but just no braking force available. Will do more tests next time the issue occurs but it does seem random.

Played on FS2024. Started from C&D and used GSX for pushback if that makes any difference.

I am using FS 2024. Made a second flight today. Didn't had the problem. So I could not reproduce it. It wasn't the same flight though. Different Airport, different livery but same variant.

@StefanL85 are you loading into a gate, and if so, are you selecting a panel state in the EFB at all?

StefanL85

@ual763 I'm loading to a gate/parking spot in cold and dark, without using the panel states on the EFB.

Did that both times. There was one difference in procedure. The first time I didn't turn on the electrical pumps to pressurerize the systems before engine startup. Figured there will be pressure supplied to both systems when engines are running. Which was the case. All indications in the green. But no stopping power.

Martyn

Thanks all. We're investigating this now.

Woolies

Excellent. Probably not going to be an easy one but happy hunting.

Experienced this the first time today. GSX used "lift for pushback" for the first time on the V2, before that on all flights a small tug was used. I also noticed that I got no callouts on takeoff and also no audio from the cabin crew after that.

It happened to me twice so far.

As an update to this, we do have a fix that is currently being tested by our beta team. Once that has been signed off the fix will be included in the upcoming update to the F28 Professional.

Just to confirm that I have the same issue

Jasemelbo

From a few tests, it looks like its an issue with GSX integration.

If I only use the pushback request from GSX and deselect GSX integration from the settings menu on the tablet, brakes work each time.

Issue is back after SU2, sitting here at the gate and the plane keeps on rolling after engine start, toe brakes and parking brake do not stop it.. hydraulic pressure is ok, issue remains if pumps are manually on. No brake pressure shown on the left gauges, pedals (to brakes) are moving. GSX integration selected, but have only done boarding with it, nothing more.

@MatzeH84 I've just had a look at this and I'm not able to replicate this behaviour using F28 v0.2.1 and SU2 at the moment.

If the System I hydraulic pressure indicator is indicating 0 PSI, it would be expected that the brakes do not function, as there is no pressure in the system. With the engines shutdown, System I brake pressure will be depleted every time the toe brakes are applied, but with the engines running, the pressure should be maintained in the green band range if all of the hydraulic pumps switches are in the NORMAL positions.

If that occurs again, would you be so kind as to attach a screenshot or video of the behaviour so we can see if we can spot anything abnormal?

Will do. Engines were running, hyd pressure in the green.
Sim restart fixed the issue. I unchecked GSX integration for now.
