November Posted April 19, 2017 Posted April 19, 2017 I'm facing a strange situation. When i try to startup the engine from a cold warthog, the RPM would not go over 30%. The startup procedures are good, inverter, apu, apugen, and the fuel pumps are on. Oddly, the fuel test button would not work ( it clicks, but there is no change in the quantity fuel indicators as the test would function ) and so the oxygen test will fail in the same way. That's strange, because i had no problems in hundreds of cold start. What's even more strange, if i start on an hot warthog, i can use alle the test buttons correctly and i can shut down and restart without a problem. I don't know if it's a bug or a problem that i can resolve Any suggestion?

Pocket Sized Posted April 19, 2017 Posted April 19, 2017 Very strange. Do you recall if the EGT raised, or stayed near zero? If it did raise, then that indicates a hung start. If it didn't budge, then the engine didn't light off due time a lack of fuel or ignition. 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.

Yurgon Posted April 19, 2017 Posted April 19, 2017 dont see any mention of battery switch Yup, I think that would explain it. If that's not it, do post a track so we can virtually look over your shoulder.
SkateZilla Posted April 19, 2017 Posted April 19, 2017 (edited) no batt power, no testing switch responses, and likely no fuel pumps. Double checking now..

Yurgon Posted April 20, 2017 Posted April 20, 2017 The startup procedures are good, inverter, apu, apugen, and the fuel pumps are on. Did you forget the Inverter Switch by chance? :music_whistling:
Pocket Sized Posted April 20, 2017 Posted April 20, 2017 If the battery was off, the APU wouldn't have started and therefore the engines wouldn't have gotten to 30%, where they stopped spooling according to the OP.

SkateZilla Posted April 20, 2017 Posted April 20, 2017 yeah, without BAT no APU Spin Up. I've stalled starting left once a looooong time ago.. I think I cut the pumps on at the wrong time, I dunno what it was, I shut everything off and started over and it was fine. Possibly errant click of engine ignition switches or something. Please Post Track, I started up the A-10C like 20 times last night no problem.

Will the CDU/MFDS/HUD ect turn on? Is it possible to jump the gun with the apu.. If you start spooling before the apu has fully spooled up. If memory serves me right the apu will not generate enough power to do anything if its under 100%. with that if it is modeled in game by moving the throttle to idle before apu its fully spooled you then allow bypass air to the engine robbing the apu of a chance to fully spool.

pr1malr8ge Posted April 22, 2017 Posted April 22, 2017 I just ran a test. If you do not wait for the apu to hit 100% before moving the throttle to idle you will never get it working.

StandingCow Posted April 22, 2017 Posted April 22, 2017 I just ran a test. If you do not wait for the apu to hit 100% before moving the throttle to idle you will never get it working. Yea, you would prob have to motor for a bit if you tried starting the engine without the APU at 100%. 5900X - 32 GB 3600 RAM - 1080TI My Twitch Channel ~Moo

November Posted April 22, 2017 Author Posted April 22, 2017 And this is the track, that shows the fact, and some function that aren't workingEnginewontstart.trk
pr1malr8ge Posted April 22, 2017 Posted April 22, 2017 (edited) November in your track you forgot the inverter switch.. It's the switch right next to the apu gen switch in the middle top of the electric controls. With out that every cold start you try will be the same.

Yurgon Posted April 22, 2017 Posted April 22, 2017 November in your track you forgot the inverter switch.. Agreed. Unlike what was written in the first post, the Inverter remained in the Off position. And that's why checklists were invented... :smartass:
