Just made a little FM test after the patch

[LuftManu]

Hello!

 

Just wanted to share some data I made yesterday, the error percentage is around 4/5%

 

I just wanted to hear some opinions, I am not really into numbers so I would like what other thinks.

 

I have chosen this aircraft because there are many reports for them in the forum

 

*Height in meters, Speed in km/h

 

** Temperature below each data

Pretty much all Wrong. I'll be back home ine 3 or so hours and correct you.

Thanks! Much apreciated! I want to have something to guide myself!

[6./ZG26_Klaus_Mann]

Working on it. Maybe I'll even make a fancy Graph. I'm testing all planes, and that takes time. 

 

German ones are done. Now for the russians

Many thanks! We need that in our squadron!

[6./ZG26_Klaus_Mann]

All done. I'll try and make something more fancy.

Messerschmitts were all done Stabilizer Nose down, Rads on Auto or W.25%; O.0%.

Mc.202 was O.25%; W.50%.

All others are at useful combat settings. All of these speeds were maintained for long enough to establish reasonable settings with a small measure of Temperature Reserve. 

 

Normal mode: Highest Continuous Mode, Combat modes lasting 20+ Minutes. 

WEP: Modes lasting at least 3-5 Minutes (1.35 ata@2600 Revs for F-4) Boosted for La-5, MiG-3 and I-16. 

 

 

If you want to make somethin fancy with tables I think you can Copy Paste out of the PDF.

How do IU put the Altitude on the Y-Axis, the Speed on the X-Axis and then add in the Plane Curves?

 

Edit: apparently Excel doesn't really like to do what I want. I'd be grateful for some advice.

Is the F-4 at the 30 min combat rating or the 1 minute emergency rating?

Made an Edit above. I don't think I will be able to do it with Excel, any Recommendations?

[6./ZG26_Klaus_Mann]

You certainly can do it with Excel, using something called "Pivot Tables".

 

It's been years since I've done one, but maybe if you google Pivot Tables you may find a straightforward tutorial?

Well, the table is way too compressed without a chance to only show parts of the speed axis and it just looks [edited].

Good job Klaus, thanks!

 

Out of curiosity, which radiator settings did you use for the La-5?

You mean one of those standard airspeed vs altitude curves with the curved top?  Not sure what you mean by "add in the plane curves".

 

To get accurate ones you'll need to ensure you've found full throttle height for each aircraft.  After that you just do an X-Y plot and add trendlines.

Edited August 11, 2016 by JG13_opcode

[6./ZG26_Klaus_Mann]

Oil fully open, Outlet fully closed, inlet fully open. Otherwise it just overheated.

Nope, just a Chart in which I can reasonably display all Aircraft Speeds. Excel doesn't have Charts able to do that. The Line Chart simply isn't up to the Job.

The Line Chart simply isn't up to the Job. 

 

Try an "X-Y" or "scatter plot" chart. 

[6./ZG26_Klaus_Mann]

And here I show my ignorance. How do  I put the Altitude on X or Y Axis? How do I assign axis really? I just luck my way through to something looking similar, but I wasn't yet able to assign the X or Y Axis to Altitude.

You have to manually edit the ranges for each data range.  There is an explanation of how to do it here:

 

https://forum.openoffice.org/en/forum/viewtopic.php?f=9&t=15232

 

I attach a small file with the before and after graphs for example.

 

XY Graph.zip

 

I am using Open Office, but I believe that Excel can open these and the graph formatting is very similar: Seawolf had the same problem with some RoF tests but was able to get it to work using this method and produced splendid charts thus:

 

Whoops wrong chart: the second one shows the altitude switched;

Flying mostly the Mig 3, I'd like to point out that in a level, straight line, you can only achieve 521 kph by closing all rads. (520 with 5% water 0% oil) You reach overheat basically at the same time you reach that speed. Can the engine keep that up for 3-5 minutes? Not so sure. I'll try tonight.

 

Ok, just did a quick test, it holds for 3-5 minutes then dies, so it's all good I guess

Nope, roughly 25-35% on the rads. With all closed I get up to 535+

IAS or TAS? I'm confused. At 0m ?

There is no difference at 0m.

Thanks for the data Klaus! I appreciate it! I will post it on my squadron forum, I will give you the credits! Thanks!

I did not see it noted which map/season (Summer/Autumn) was used, maybe good to mention this, apologies if i missed it.

After last update I ´ve noted in the Bf-109 F and G, that the THS (trimmable Horizontal Stabilizer) handwheel have 4 turns of travel, from full nose-down to full nose-up, (as we claim from the initial release of the game), and how it work in the real aircraft.

Before the last update, The Bf-109 THS wheel had one turn only, from full nose-down to full nose-up, but i not found anything in the "change log" about the chande of THS wheel turns. ..WHY?  secret changes?

Arent the combatmodes for 109s supposed to last at least 30 minutes? Not just 20+..?

It's no secret. This was discussed ad nauseum in other threads. It was simply addressed in the patch.

[JG13_opcode]

The speed at which the wheel turns in game means nothing. It is just an animation.

Im on boring audioconference so I did quick&dirty graph out of Klaus data. Its in pdf format. Enjoy and dont come back to me that it sucks

Good to know!  Where do you guys find this stuff out?

Edited August 11, 2016 by JG13_opcode

[6./ZG26_Klaus_Mann]

 

Autumn in Il-2 is pretty much exactly that. The Maximum Deviation in Airpressure is normally in the area of +/- 2.5% in the extreme. But I think in our Quickmission Scenario it's pretty much 1013.

Yeah, I know what the standard atmo is, but how do you know the Autumn map conforms to it?  Dev posts?  Secret altimeter controls I'm not aware of?

[JtD]

Yes, developers statement.
