RazerVon Posted June 22, 2023 Share Posted June 22, 2023 (edited) After a short while in flight you start gaining fuel. Indicated by fuel flow going negative. Caused by mach 1.42. Answer from developer: Fixed in next update. After landing with the fuel bug. Edited July 7, 2023 by RazerVon 2 1 Link to comment Share on other sites More sharing options...
SFJackBauer Posted June 22, 2023 Share Posted June 22, 2023 Attached track. In this case I air-spawned clean on Caucasus, running max afterburner. Once the CFTs deplete fuel indicator goes to zero and fuel flow on ENG display goes negative as @RazerVon screenshot. F15E fuel bug zero.trk 2 1 Link to comment Share on other sites More sharing options...

western_JPN Posted June 23, 2023 Share Posted June 23, 2023 I think this is coming from the same root. Playing Instant Action - Sinai map - Ready for Take Off (Hot start on the runway end) FUEL QTY gauge starts from ZERO and counts up to INTL=13000 lbs (in 9 seconds) / Total 30500 lbs (in 23 seconds).

That is completely normal. FQI does not work without power applied. Simulated refueling with power off. Not bug. Feature.

RazerVon Posted June 23, 2023 Author Share Posted June 23, 2023 Update, I honed in how this is triggered: Speed of over Mach 1.42 at over 30,000 feet. Link to comment Share on other sites More sharing options...

Yup, can confirm this is indeed a bug, I noticed the fuel flow meter starting to go haywire after mach 1.4+.

Mobius_11804 Posted June 23, 2023 Share Posted June 23, 2023 had the Bug as well.. Both Cans lit for 10 mins or so in the Cold and Dark Tutorial and after reaching a certain Speed and Altitude both PPH's, as well as the Totalizer went to Zero. I mean, it's a marvellous Piece of Tech if it works like that IRL, but i doubt it. Link to comment Share on other sites More sharing options...

I just did the first training mission and thought "why not just go up and do a Mach flight now?" and I basically got four impressions: - at some point my FF went to 0 and I could go for ages. Thought something was broken and even considered unlimited fuel being active in the mission and that happening after emptying the CFTS perhaps to be a thing. - tops out at under 1.8 in level flight. Tried at the typical 36.5k and 42k as well as going down from the latter to the first with the waterline at the horizon. - trying to go over 1.8 in a dive is bad. Lost like a third of my right wing, but could at least land the thing with the DCS typical ever burning damage model. Probably was too fast too low during that dive test. - I like the module, anyways! If I'm not completely mistaken CFTs are cleared for up to M 2.0 and I've definitely seen some of the content creators do somewhere around 2.2 with no issues and I guess with the thrust alone and clean setup, it should be possible to reach that, especially when there's a CFT limit that you basically should stay within. There'd be no reason to have that if you couldn't even get there. Source: trustmebro ('cos of 1.16). Didn't even notice it basically AAR'd, because I didn't mess with the MFD pages yet 1 Link to comment Share on other sites More sharing options...

Feature. Are you implying the FQI is a totalizer as opposed to a quantity gauge? I believe it is actually a quantity gauge (either float or capacitive) Link to comment Share on other sites More sharing options...

I believe it is actually a quantity gauge (either float or capacitive) It gets signals from a sending unit that reads quantities through capacitance probes in the tank. None of it works without power. Link to comment Share on other sites More sharing options...

None of it works without power. OK, no I misunderstood then, I thought you were saying the negative numbers came from simulated incorrect fuel totalizers. The only data I saw mentioned float sensors, did they upgrade them to capacitive sensors at some point? Seems like a good idea in a fighter Edited June 23, 2023 by jaylw314 Link to comment Share on other sites More sharing options...
Dataduffy Posted June 25, 2023 Share Posted June 25, 2023 I absolutely love this module, however this fuel bug is really annoying. Really hope it gets fixed quickly. Other than that.... having an absolute blast with the module. Great plane! Link to comment Share on other sites More sharing options...
