Looking forward to BS-FC2 joint ops in LOCERF style.

Here's what I did - I shut down the engine exactly 100 sec after the START VLV light goes off, then I wait 100 sec more and initiate another start. It starts normally. I repeated the same sequence few times and the engine always spools up.

Well, you can extrapolate if you wish. There's nothing given in the manuals about how long it takes for the starter to stop. From RL experience I know it spools down much faster than the compressor but hey, I'm not a programmer so I can't say how that would be implemented in BS. It's an issue that devs are well aware of but there have been some technical difficulties. IMO it doesn't affect gameplay at all. Tell me something - why would you need to shut down an engine right after it stabilizes at idle then to restart it all over?

The 'bug' is that the starter should spool down faster than the compressor but currently it is not worth to adjust it. I think we can live with that, some technical self discipline won't hurt ;)

LOL, nice sig comrade ;) Good luck with the new version.

It is indeed a bug but it has a logical explanation. After discussing the subject with Yo-Yo (ED's physical models lead programmer) I got the idea what's behind it. The reason this to happen is the spool down time of the starter itself. Remember it's actually an air turbine driving a spool engaged to the accessory gearbox of the engine. At approximately 60% compressor RPM the starter disengages (START VLV light goes off) but it's turbine keeps turning and fully spools down for approx. 100 seconds. We think that this is too long but there is nothing given in the manuals of the TV3-117 for that. Trying to adjust that time has led to some problems AFAIK so for the moment it stays as is. So what you experience now with the engine unable to start is that you initiate a start with compressor RPM zero while the starter is still spooling down- it's driveshaft gets overtorqued and it shears. So I suggest 3 min 20 seconds (200 sec) pause after START VLV light extinguishes before initiating a start of the same engine, assuming compressor RPM is zero. Hope it's clear now.

No. What MaverickF22 does (starting an engine with throttle at Auto) is completely possible IRL and I've seen it myself on the very same TV3-117VMA engine - the fuel control unit had an Idle mode failure (the governor cam was stuck) and the engine has no problem doing that but that leads to excessive wear because it increases engine power while it's still "cold". You need the oil to warm up to a certain temperature in order to increase engine's power above Idle. Though this wear is not modeled in BS but FYI doing it will be penalized IRL ;)

Nr=90% is 272RPM which corresponds to 100% (15000RPM) free turbine RPM. As for the letting the engine running longer than a minute - you normally do that before shutting it down for cooling but it shouldn't affect the start process at all.

It seems like it's longer than 1 minute. I'm now investigating it deeper but it seems to me that we have a spool down time bug. This is exactly starter driveshaft shear but it shouldn't be happening when the compressor RPM reads zero. I'll bring that to the devs. Thanks for the finding, good catch.

The Haze modeling in FC2 is different - it's closer to "Basic" settings. I wouldn't say that FC2 looks better though.

The x-feed valve on every multi-engine aircraft being fixed or rotary wing is normally closed. It's purpose is to supply fuel from one tank (or group of tanks) to all engines or fuel from all tanks to one engine. I.e. in BS you open it when you run low on fuel or you have an engine out. As to what the user's problem is - we can only guess until he provides a track. One possible reason is when you hit the Start button while the compressor is still spooling down - especially on the ground, in flight you'are allowed to start at up to 7% compressor RPM at windmilling. That will cause the starter's driveshaft to shear and it's modeled in BS.

Myself, I don't use LEAVU just beacuse I have a single 19" monitor and I have to Alt-Tab every time I want to have a look at the displays. I hosted the DL once with Yoda while FC2 was still in development and I was amazed by the gameplay improvement it gives. So for me it is definitely a feature, a great one, not even near to be considered a cheat. I keep wandering though where some of you guys get those 'cheating' ideas from...

Ah memories....

You need to try Black Shark to undertsand what a true flight simulator means. The rest is compromise.

That's just because you haven't tried Black Shark.

Consider also: 1. Su-27S empty weight - 16380kg 2. F-15C empty weight - 12700kg 3. MiG-29A (9-12A) empty weight -10450kg (thrust - 2x8300kgf)

I don't use Saitek profiles for BS, same applies for FC2. I strongly recommend it.

Useless. Most effective bombs in LO seem to be the clusters - RBK-250/500 (pretty even BTW) and Mk 20. I use only them, other that might come in hand are the concrete penetration like BetAB-500, Mk 84 is also nice. From the rockets anything bellow S-13 is waste of time. A-10 is limited in this area but then it has the GAU-8.

2xKh-29L (for ships) 2xKh-25ML 2xUB-13 2xRBK-250 2xR-60

They are not removed, just blanked.

T-50 has been tested up to 27' AOA within the first 3 flights.

Thx everyone, I made it yet another year :)

My precious...

A second test flight has been conducted at 12th, 57 min long, with the new paint. Afterward the plane has been disassembled, either for structural changes or for transportation to Zhukovskiy.
