Oh, I can't quite determine the problem, it might not be the engine nor the carb heat, although it must be connected, as after another 2 hour flight the CHT rose again during flight without the use of carb heat (cruise settings of 25 MP at 2200RPM), and I checked now the engine condition is still 99,8 something, but the residues level in the oil filter have risen.

I think it requires some further investigation..

I changed the

CONDITION_ENGINE=59.891269 to CONDITION_ENGINE=99.891269

And now the high CHT is back to normal again.

After 2.5 hours (about 45 minutes use of carb heat during which I saw CHT rise from 185 to 240 F, and then carb heat in, after which the rise stopped) I have these which have changed a lot

CONDITION_ENGINE=59.891269

CONDITION_FINGER_FILTER=76.487359

The rest of the conditions is between the 98 and 100 percent of its original state.

Thanks Marcel!

For your information, I have done all my tests after a reset before each flight, ran it from the default startup flight, checked everything according to the manual before taking off.

It seems more like some fsx problem

I am going to try to untick the 'engine stress damages engine' in the realism, as I found that one ticked. And after getting the problem I will shut the engine down again before it damages because of heat, shut down fsx and take a look at the data.cfg.

Janus

[Scratches...?]

Haha, yesterday I found an entry in the data.cfg about the experience of the repairman!

funny!

[unusable aircraft]

I can report now that I have reached 9.3 hours on the engine before it started going to the redline on descent to an airport, using bliksimpies rules..

But I did see a huge rise in cruise CHT over those hours, I started on a cruise with little over 180 F CHT and ended at 240 F CHT in cruise on the last flight. All flights were done on 7500 feet with OAT between -6 and +5C.

Slowly (but still way too fast) Engine health decreases with usage of the carb heat. I did get some icing now on fsx real world weather due to some rain, not much rain, but it still makes climbing very hard on 19.5 MAP (20 MAP being the line drawn by bliksimpie/the manual?)

Janus

[unusable aircraft]

Yes, I can definitely recommend that!

Try some cold rain!:DIt's quite funny..

Then my guess would be that there was something else wrong with the engine - did you allow sufficient warm-up time at idle? Check the oil pressure and level? Filter? Have the right oil for the conditions? Coolant level? Changed from Avgas to Mogas? Fuel switched on? Fuel Pump on?

There is no carb icing effect at idle in FSX because to do so would be too difficult to discriminate between a barely-running engine and one switched off.

FSX just isn't complex enough in its derivation of the causes and effects of carb icing, nor its symptoms. You have something else causing the problem.

Yes I checked all the above, but what are you saying about changing the fuel?? What would that do for your engine?

Hmm, I think you're right. That made me think. I now think the icing was caused by a program called 'Open Clouds', a quite good program though or maybe by fsuipc settings. It was very heavy carb icing I can say, nothing fsx, indeed, would be able to do in these clear conditions.

Thanks!

About the CHT, not using the carb heat except for the above mentioned situations fixed it for me also! Seems like the Carb heat damages the engine before the CHT redlines, causing a tendency to reach higher than normal CHTs after starting the engine the next time.

I might be so very wrong though, and I would like to hear your opinion on it if you have one!

But I would like to see the hidden linkage between the carb heat and the CHT to be reconsidered (not the right word, but I mean: to look at it) and changed to a, i think more realistic, little bit milder influence (or whatever solution you guys can think of) for the service pack, if of course you agree with me that it seems a bit unrealistic this way, and it can be remedied!

Keep up the good work!

Last Flight I only got the engine running more than idle by using the carb heat, during takeoff also, because otherwise, BANG engine running 600 rpm.

Still I think the engine damages way too fast by this wrong carb heat usage. You don't hear about this every single day in real do you?

It's ok of course that the engine damages because of high CHT, that's normal, but why is it persistent in the tendency to produce high CHTs after one time seeing the trend of developing a high CHT even if you shut down the engine before it ever redlines.

[unusable aircraft]

I believe there is something about it in the german support forums. Something with the carb heat and high throttle..

I have it too, i think it is too easy to trigger such temperatures, you should be able to run 25 MP at 2200 RPM right?

Today I flew in cold weather, and flying without carb heat was impossible ( in the -in position engine goes back to idle in 2 seconds, and nooo, it was 32 km visibility, no clouds or rain at all, just -3 degrees celcius), and within the hour the engine went hot and even carb heat in did not help anymore.

But I'm doing some more testing on this.

[Well uhh....]

However... this is only a fact when all systems are okay. So if you are having problems getting the engines started or if they stop just like that, you probably need to do a walkaround and, if nothing special comes up, do some maintainance. You don't really need to read the manuals just to get the engines started, but you do need to read the manuals to make sure the engines CAN start... or to find out why they won't anymore.

Er... that can hardly be the problem after a smooth taxi... Maybe the tank is empty (although I can't imagine he would have missed THAT!), but with the fuel valve shut you won't be able to taxi... afaik... (Did I catch you on a mistake there...? Or did I miss something... again...? )

I guess fuel in the fuel lines after the shutoff valve is simulated! When the fuel lines are dry the engine stops

[Graphical issues]

As of yesterday evening it was still there though.

I did however get ctds again with the katana running, so I checked the fsx.cfg again (as you suggested might be able to shit up everyhting), just to be sure, and then I found one duplicate that I had overseen: One that was put in with Jesus Altuves Memfix=1 program, it put an extra line 'shader primed' or something in the fsx.cfg which was already there. And since I was one of the few people that the fix didn't work on I just took the whole fix out and that got rid of the CTDs. So maybe a hint to check te fsx.cfg if anyone else gets CTDs.

And I have not seen the above mentioned graphical issues after I took the fix away, so maybe??

Actually I had a little adventure yesterday when flying over open water (40 miles to nearest) and suddenly the CHT went through the roof. But the engine just kept on going on a low powersettings, no problems at all. On the ground I checked the radiator fluids and oil quantity, but both were more than satisfactory. Engine needed a little fixing though after the flight, but no idea what was fixed exactly. My guess is that the radiator fluids weren't reaching the engine for some reason, but what could get it blocked is still a mystery for me!

I just have to say it again, you guys are awesome! For the plane , the incredible detail and the feeling of flying out there for real, but also for the great support and interest you all show! Keep up the good work!

A very excited and happy Janus

[Graphical issues]

Thanks for the tips!

Ok, no duplicates in the fsx.cfg. Still had the problems.

After that I tried to rebuild the shader cache, and no problems so far! I'll report back later

Janus

[Graphical issues]

And all of a sudden just a few seconds after I took the last screenshot It went back to normal.. Quite strange

[Graphical issues]

System specs? How are you running FSX? Full screen, windowed, multi screen. Absolutely nothing to go on here. If you can't think what information might be required, supply it all.

If it's happening with other aircraft too, then obviously it's not a Katana-specific issue, is it?

I'm running fsx in full screen and as administrator, I have a Nvidia 8600GTS, and run windows 7 with 64 bits. Although I don't think that is relevant, because I had it before on vista 32bits.

What I mean with other aircraft is, is that I don't have it on default aircrafts, but sometimes I do have it on aircraft I find on flightsim.com and the avsim library, but again not all. Yes, It is very probably linked to something in my system, but no idea as to what.

When I have this problem I reduce the size of the popup window, and then it's fixed for a little while (1 or 2 mins). I will also include a picture of the gps shining though on the OAT and clock, that one I forgot to add..

So, in case I wasn't clear enough , I would like to know if anyone knows anything about this kind of behaviour. It's just meant to be sure. It might be something so very simple I completely missed, and that would be a shame.

;)Janus

[Graphical issues]

Hello, I noticed that after some time, mostly cold and dark, I get some graphical issues! Take a look at the screenshots I will put in here. Also gps shining through on OAT and clock sometimes.

Any idea what this might be caused by? I have seen it on some other 3rd party aircraft also..

Thanks in advance

[Failure to launch on selection]

This product does NOT have to be activated, but you DO need to have admini9strator rights when installing.

Oh sorry, I meant I also had crashes on loading the katana, not about the activation!

Running fsx as administrator now it does save data (which it did not before, for example wheel fairings appearing again on next startup after being removed), and it does not crash anymore on me. Little note though that I removed the rxp gns line from the panel config.

[Failure to launch on selection]

I had exactly the same problem, but now I tried running fsx.exe as administrator and it seems to be working!

Marcel, this aircraft is soooo nice! I have no words for it!

I love to see the standards of details of systems and aircraft in flightsim get higher and higher because of people like you!

Congrats, and keep up the good work.
