Azazel Posted August 17, 2016 Posted August 17, 2016 Attaching a screen shot that shows the situation. In it the viewer can see that my throttles are set above the Afterburner thresh hold hash mark and that the engines are at 100% RPMs but that both nozzle pos gauges are not in their after burner positions and in the pit there was no afterburner roar noise. The problem was simply solved in-flight by pulling the throttle back below the afterburner hash mark and pushing it forward. Not sure if this is a bug or intended behavior?

escaner Posted August 18, 2016 Posted August 18, 2016 Your fuel flow was also in afterburner range, strange... [sIGPIC][/sIGPIC]
autogyro Posted August 18, 2016 Posted August 18, 2016 Could this be related to the as yet unimplemented flame out and compressor stall modeling? I've definitely experienced this as it caused me to crash on take off.
autogyro Posted August 19, 2016 Posted August 19, 2016 Sounds much more like a bird strike to me. What's your birds setting ? None. I have that turned off, although I was playing on Open Conflict, which may have overridden my off setting. I never even got off the runway.
NeilWillis Posted August 19, 2016 Posted August 19, 2016 Any multiplayer mission overrides your local options, so I would suggest a bird strike is the most likely cause. Can't help with the first bug though. Not encountered it here I am afraid, but I use the Warthog throttle detents as afterburner gates. That system works perfectly.

That system works perfectly. Yeah, this screen shot was a one off. I have only encountered the issue once or twice so far. It is generally not an issue, but when I caught it the second time I felt compelled to share it.

Svend_Dellepude Posted August 20, 2016 Posted August 20, 2016 I tried this a few times too. It's not related to birds. :) [sIGPIC][/sIGPIC] Win10 64, Asus Maximus VIII Formula, i5 6600K, Geforce 980 GTX Ti, 32 GB Ram, Samsung EVO SSD.
escaner Posted August 21, 2016 Posted August 21, 2016 It happened to me too. Left engine afterburner didn't ignite, but fuel flow was there. No caution lights. Right one was ok. Moving left throttle back to MIL and again into MAX fixed it. [sIGPIC][/sIGPIC]
Juancio Posted August 23, 2016 Posted August 23, 2016 Im having the same problem, even made a thread about it, here: http://forums.eagle.ru/showthread.php?t=171851 I think its related to some kind of imput lag or response problem. I find it very annoying.
NeilWillis Posted August 23, 2016 Posted August 23, 2016 I have noticed that the throttles are very sensitive in the F-5. Usually, I just lock my throttles together, and they synch without an issue, but in the F-5, I have to keep them separated, to keep them matching in the cockpit. The difference can be very distinct.
escaner Posted August 23, 2016 Posted August 23, 2016 Not an axis problem. Throttle are registered correctly as the OP showed. Fuel flow is also in the afterburner range, so it is being injected but fails to ignite, and nozzle does not open. It looks more like a feature to me, these early jet engines didn't have FADECs. Maybe it happens when we move the throttles too fast, will check it... [sIGPIC][/sIGPIC]
Pocket Sized Posted September 26, 2016 Posted September 26, 2016 Yeah, the burners will be very hesitant to light in certain flight regimes. The engine doesn't know or care they failed to ignite so it carries right on dumping fuel out the tail pipes... DCS modules are built up to a spec, not down to a schedule. In order to utilize a system to your advantage, you must know how it works.
CHSubZero Posted September 26, 2016 Posted September 26, 2016 It happened to me too. Left engine afterburner didn't ignite, but fuel flow was there. No caution lights. Right one was ok. Moving left throttle back to MIL and again into MAX fixed it. Same problem and "workaround " here :) Aviation Livery - Explore Military Aircraft Liveries My Mods: DCS User Files
Bucic Posted December 22, 2023 Posted December 22, 2023 This bug is still present in the latest OB build. I managed to re-trigger the behavior several times within 20 minutes on mouse and keyboard. I think I could only do it while NOT decreasing RPM all the way to idle and ramping up to AB subsequently by holding PageUp. Every single time when AB did not light up the fuel consumption corresponded to normal full AB operation. The track file is a bit lengthy unfortunatelly. bug F-5E ABdecember 01.trk 1 F-5E simpit cockpit dimensions and flight controls Kill the Bloom - shader glow mod Poor audio Doppler effect in DCS [bug] Trees - huge performance hit especially up close
navyjoker2000 Posted January 30, 2024 Posted January 30, 2024 Same issue. Though it is not every time it doesn't activate. Very intermittent. I can't pin down when and what doesn't allow AB to activate.

navyjoker2000 Posted January 30, 2024 Posted January 30, 2024 Controller until my throttle gets shipped. Throttle is bound to A and B buttons

So we need someone with axis controller to confirm it is not specific to button-driven setup. Or we can just assume it's still the same bug that occurs intermittently for button and axis setups alike.

=475FG= Dawger Posted January 30, 2024 Posted January 30, 2024 I can confirm occasional failure to light AB on one or both engines with Warthog throttle but fuel flow always indicates lower than AB rates when it happens. Back to idle and forward always fixes it.

Is setting back to idle and forward by purpose? I doubt it because unless other malfunction with irl aircraft is present I doubt real pilot would have to do that in dog fight, etc. makes me believe it is a bug in DCS with AB

Idle and back up is a DCS thing but I can tell you that its what a real pilot would do if it actually happened as it is a mechanical device and you never know what will work. It would suck in a fight.
