gulredrel Posted July 15, 2023 Posted July 15, 2023 Hello, just flew the Huey after the latest updates. Needle split nice, thanks... I know there are some threads about engine, flight model and fuel consumption. But couldn't find something about the fuel pressure. At least all my searched for "fuel pressure" or "pressure" didn't resulted in something like the following. What caught my eye was the fuel pressure gauge. After switching on the fuel pump, the fuel pressure gauge goes all the way to 50 psi and stays there regardless of engine operation. As there's a green operating range marked on the gauge and the manual also states: "5 to 35 PSI normal." this should be a bug? Maybe it's related to the fuel consumption issue but just want to be sure this also gets some attention. Tested in version DCS/2.8.6.41363 MT Map was Syria at around 23°C I think, if this matters, haven't tried on different maps yet but should be easy to check. Just load on the ramp cold and dark and switch on fuel pump. Thanks Jens 3 1
Flappie Posted July 19, 2023 Posted July 19, 2023 It looks like a random bug. I only managed to replicate it in Rota (Mariana Islands), with three different Huey slots (hot, ramp, and ground start cold). Unfortunately, I did not record a trac, and it won't happen again... If you get this again, preferable at the very beginning of a mission, please attach a short DCS track. ---
gulredrel Posted July 20, 2023 Author Posted July 20, 2023 Thanks for trying. Will create a track, but this could take some time as my PC is several 100 km away for the next time At least I can say, it was cold and dark ramp start at Pinarbashi in northern Cyprus.

Flappie Posted July 20, 2023 Posted July 20, 2023 Thanks miki. Unfortunately, the track replay shows the counter behaving as it should. It really looks like a random bug. ---
Flappie Posted July 20, 2023 Posted July 20, 2023 The same just happened to me: I reproduced the bug in different Huey slots, saved the track, and it won't show the bug. I took a video. It should motivate devs to try and try again until they see the issue and understand how it happens. 4 1 ---
IJammer Posted July 31, 2023 Posted July 31, 2023 After the last update... and after landing the Huey I like to shut it down and stop the rotors... the last time I tried this, zero'ed the throttle, cut the fuel and raised the pitch after a while to stall the rotors... nothing! the rotors continued to idle even after the fuel was cut (has it found a new reserve tank lel ?) It seems that the UH-1 Huey has been screwed with and is now effectively a none working model... I get the impression that their are so many moduels now that things are running away from the 'fix a bug' crew! Hopefully we can get the Huey sorted... 1

virgo47 Posted September 10, 2024 Posted September 10, 2024 I found this thread after searching for "fuel pressure zero". Because that's what I saw on the multiplayer server in one of UH-1H. I'm not sure what it showed at the start, but there was no other warning, I didn't crash the helo, so I have no idea why the gauge didn't work (or stopped working, not sure). Perhaps also a random issue. I wanted to reproduce it, but could not - and didn't take any track from the first flight.

artao Posted September 19, 2024 Posted September 19, 2024 I was going to ask about this. As far as I can tell, this happens when doing parts of the startup procedure out of order. I've had it show both max and nothing for pressure. I can't quite work out exactly what part of the startup sequence messes it up tho. But I THINK it has to do with turning on the inverter before the engine is fully spooled up, also possibly due to disconnecting ground power too soon. I can not reliably reproduce it, but when it happens that seems to be the commonality.
