up-to-date performance charts

[VRPilot]

Hi,

 

does anybody has up-to-date (1.008) performance charts of the planes like G2,F4, Yak ...?

 

like speed vs altitude, climb? Esp. for the F-4 with 1.3ATA @ 2600rpm (30min Dauerleistung)

 

Thx

[Yakdriver]

are there ANY such charts - even for older versions?

[KpaxBos]

There is this compilation at :

http://forum.il2sturmovik.com/topic/13879-performances-des-appareils/   (see end of post).

There are no charts but data could be used to do some/

 

There was a performance chart (altitude vs max speed) writen by Chuck_Owl but it is no more available. Ask ChiefRedCloud if he has it (Chuck grant him permission to distribute his guides).

 

Have fun

You can find detailled information (in german) on our website. Just click on the left side on "Achsenmächte" or "Allierte" for performance data. Or "Im Vergleich" to compare them.

 

This could be helpful, too:

As we all know, there is some conflicting real world data out there, so it would be nice to know which set of real world data the devs used for the flight models. But until 1C/777 provides a way to log data during flight, as 1C did in IL-2 with DeviceLink, or as 1C did in CoD with C#, no one can say with any certainty how well the planes are matching the real world data. Just too many potential sim pilot errors can be made during testing that can corrupt the results.

 

This statement is based on the hundreds of test logs I have reviewed over the past 10+ from several different flight sim. I found that most of the errors were in the way the user performed the in-game test, and not an actual error in the FM. For example, not taking into account the difference in the in-game atmosphere and the real world data, which is typically corrected/converted to standard atmosphere, but not always! Another example, in WWII some countries the beginning of a rate of climb test started from a dead stop on the runway, where as others the beginning of a rate of climb test started with the plane air born at a low altitude. Not a big impact on the rate of climb data, but it does affect the time to climb results. Little difference like that can have a big effect on the results.

 

So, until we have a way to log the in-game data, any and all in-game testing should be taken with a grain of salt. As a bare minimum a video (track file) should be generated during the test so others can review the methods used during testing.

 

On a related note, Pilot Combat Accounts.. The are pretty much worthless to say anything about plane performance!

 

In that pilot combat accounts are typically one sided stories that says more about the pilot vs pilot skill than plane vs plane performance.. That and the pilot account typically does not contain enough information to recreate the scenario in-game to see if you can obtain the same results, let alone the other planes state..

 

For example, for every German pilot combat account of his Bf109 being able to out turn a Spitfire, their is a British pilot combat account of his Spitfire being able to out turn a Bf109..

 

Yet to this day people still think some sort of statistical average can be gleamed from pilot accounts.. But that is a pipe dream IMHO, for so many reasons, just to name one, you never get a chance to read the post action combat reports for the pilots that were killed in action!

I'm a bit disappointed by the La5 performances from this graphics. I thought she was supposed to be the quickest VVS plane and according to those, Yacks outrun her ! 

 

EDIT : better diving speed then?

La7 FN was supposed to be the best.

I heard it was likend to the p47 thunderbolt.

 

La3 and la5 were pants for dogfighting.....so I have read.

 

So BOS gets that right.

 

All aircraft have their best variants.

Sorry but at least speed test is not accurate for most planes here.  So dont count on these speed chart.

Instead of accusing our data to be inaccurate without any explanation, rather share your data. I bet the differences appear because you used different conditions, power and difficulty settings than we did. This is exactly what we experienced when we started the first tests not yet standardised.

On the other hand, I've asked you in another thread where you got your data and did get no reply. Share your data?!

[Stab/ZG26-Ruhland]

And I gave you an answer. Not my fault if you missed it.

[GOAT-ACEOFACES]

Looks like this thread is shaping up to prove my point

[StG2_Manfred]

Ok, point for you I actually missed it, sorry.

This page tells the short version of the story pretty well: http://www.airpages.ru/eng/ru/la5.shtml

 

Early La-5 version was maybe as fast as the Yak-9 1942 (or late Yak-7B or Yak-1 105PF) but the later models picked up quite a bit of speed. The early La-5 we have is slightly better than the earliest sent to the front but its still mostly just a LaGG-3 with a radial engine bolted onto it. It's heavy and the aerodynamics are not yet as well refined as the later models. The La-5F and FN picked up increased speed from their engine and aerodynamic improvements but also in weight reduction and better construction. So as the series goes on they get faster and they get better manoeuvrability too.
