agrasyuk Posted November 14, 2011 Posted November 14, 2011 asking since i tried it last night and after about 10 seconds of hanging upside-down had absolutely everything shutdown on me. Engines, HUD, MFCD's, even the warning panel was dim, completely cold aircraft. is this how its supposed to be, or a bug? (sorry, no track) Anton. My pit build thread . Simple and cheap UFC project
EtherealN Posted November 14, 2011 Posted November 14, 2011 About 10 seconds. :) The A-10 has an auxiliary fuel tank that is fed by the rest of the system to feed the engines during inverted flight (well, technically it's negative G that matters, but this usually only becomes an issue specifically with inverted flight, that G-profile wouldn't be sustained very long when initiating a dive). Once this runs dry, your engines cease to be fed fuel, and the shut down. This is all as it should be, but lots of fun when you first encounter it. For me I "noticed" this feature back in testing while doing some stunts at low level, flying inverted over another guy who was heading in to land. I was surprised, to say the least, and I have never worked so hard and so fast to get my engines spooled back up. :D [sIGPIC][/sIGPIC] Daniel "EtherealN" Agorander | Даниэль "эфирныйн" Агорандер Intel i7 2600K @ 4.4GHz, ASUS Sabertooth P67, 8GB Corsair Vengeance @ 1600MHz, ASUS GTX 560Ti DirectCU II 1GB, Samsung 830series 512GB SSD, Corsair AX850w, two BENQ screens and TM HOTAS Warthog DCS: A-10C Warthog FAQ | DCS: P-51D FAQ | Remember to read the Forum Rules | | | Life of a Game Tester
Speed Posted November 14, 2011 Posted November 14, 2011 Yea, the A-10 is not meant to be flown inverted. I think it has some kind of small, inverted-flight tanks to supply the engines so that you can fly upside down for a short period, but the main fuel tanks are gravity fed I think. So if you need to fly for a while inverted, cut the throttle to idle- you will use up your inverted feed fuel much more slowly. Intelligent discourse can only begin with the honest admission of your own fallibility.

ralfidude Posted November 14, 2011 Posted November 14, 2011 10 seconds if you sustain inverted level flight.... I was going to do a top gun moment of flying upside down, on top of my wingman and wave hello. But as soon as you fly inverted, the nose starts to drop towards the ground, to which you respond by pushing the stick forward, which causes even more negative Gs. Lets just say it took about 3 seconds before everything shut down, and I was too low to restart... My spine had a wonderful time with the ejector seat boosters... :( [sIGPIC]http://i17.photobucket.com/albums/b66/ralfidude/redofullalmost_zpsa942f3fe.gif[/sIGPIC]
XarBat Posted November 14, 2011 Posted November 14, 2011 So far I have not been able to restart an engine that has shut down due to negative G even after motoring it for over 30 seconds. Have not tried it with 1.1.1.0 yet.
Ghillied raptor Posted November 14, 2011 Posted November 14, 2011 Wait, does the auxiliary fuel tank refills after a while? I'm surprised that this still happens in modern planes. I thought the fuel injectors changed that. Are all planes like that?
Eddie Posted November 14, 2011 Posted November 14, 2011 Not all, but certainly a fair few. Most can fly negative g for longer than the hog, but most are still limited.
Guest Fury_007 Posted November 14, 2011 Posted November 14, 2011 I was able to fly inverted for about 40 seconds at idle. I got up a bunch of speed and then threw throttles to idle before rolling over. The engines didn't quit so I flipped back over not wanting to push it. Anyone gone longer?

dok_rp Posted November 14, 2011 Posted November 14, 2011 This effect was inserted when Flaming Cliffs 1.2 came out a looong time ago. The first planes from the franchise to exhibit is were the Su25 and Su25T.
Lumper Posted November 14, 2011 Posted November 14, 2011 I would lay odds that you get good fuel flow even upside down, but oil flow is probably near "0". Lumper ------------------------------------------- When the going gets tough, the smart cutout. [sIGPIC][/sIGPIC]
Amarok_73 Posted November 14, 2011 Posted November 14, 2011 To be strict, on the question asked in subject I would answer "until it will fall". At least, after the engines will shut down, plane still can fly inverted. ;-) Natural Born Kamikaze ------------------------- AMD Ryzen 5 3600, AMD Fatal1ty B450 Gaming K4, AMD Radeon RX 5700 XT, 32 GB RAM Corsair Vengeance LPX, PSU Modecom Volcano 750W, Virpil Constellation Alpha Prime on Moza AB9 base, Virpil MongoosT-50CM3 Throttle, Turtle Beach VelocityOne Rudder.
agrasyuk Posted November 14, 2011 Author Posted November 14, 2011 well if you want to be all that strict - the question was not how long plane can fly , but how long it can be flown which kinda implies being under pilot control :) but i get your drift.

NO WAY! :D If you notice the engine failure quickly (like a good pilot should ;)) then you don't need the APU to restart the engines. All you need to do is push the engine operate switches to ignition, and provided the core RPM is still high enough they will re-light. Speed is essential when it comes to an engine flame out, both in respect of spotting the flame out and reacting to it.
