When error due to the scale is considered the SPITII and 109 climbing times are considered equal when compared each other in both (RL and GAME).
Exactly.....

Ok, with 75lbs. less he should expect better performance then. Is he getting it? No, he isn't. Why? Because there is a severe problem with the FM. That's the point of this thread by the way.

You can try and match the weight exactly in game, then do the testing and share the results with us.

Yes I know, thats why I bold'd the T for blind people :-P I did not have those figures to hand but I did have those, so i used them to giver people an idea. It was just an example. If you are told best climb speed is 250km/h and you stick to that IAS throughout your test surely you have done it wrong? Same for spit, hurricane and flying pigs...

Where?

I don't see it in terms of speed and climb numbers. All aircraft performance is a percentage range even under fixed standard conditions.

Aircraft performance comparision is all relative.

The relative performance appears correct. All aircraft have a similar margin of error applied.

What more do you want? That is the most important thing in a "simulation".

It is much more important than specific performance. You can get the specific performance absolutely right within the percentage range and completely screw up the relative performance.

Exactly.

You were correct and I only posted to confirm you had the same ones as found for the Bf-109E.

You are correct too in not only do you to have to maintain the correct climb speed, you have to fly the test correctly.

Climb test generally are conducted by begining at a lower altitude and do not start until the climb is stabilized as well as at the starting target altitude. They end at a target altitude, too. That becomes a raw data point for that altitude band. Typically this is a 1000 foot band with the test airplane begining its climb 500 feet below and ending it 500 feet above that 1000 foot band. In otherwords, 2000 feet of altitude are required to estabilish climb rate data in a 1000 foot band.

Those "climb charts" guys like to quote are extrapolated from a few of these points and the raw data converted to standard conditions. There is insturment error, flight error, and pilot error in all it.

The pilot does not hop in and start from the runway to reach altitude with the stop watch running and marking the VSI. The chart is an idealized extrapolation of a few data points.

Crump are the fligth models for the SpitIa and Hurri rotol correct then?

Lol how it could be correct if both these planes are just way too slow even for 87 octan fuel versions? You people read what was written in these forum?

I see what you mean with the percentage range and relative performance, but this is not the case. No one would complain this much if it would be.

I am sorry but this is quite obvious to any virtual pilot who actually flies this sim.

In relation to each other, I think the performance is correct.

Is the specific performance of any airplane in the game correct? Spitfire, Hurricane, Bf-109?? Not really.

Is the relationship's based on performance correct for all the fighters? Yes

So what your saying is... The game feels right from what is in writen in pilots accounts?

Sorry thats what i call folklore. Its not science. Even when written by an ace. Fear adrenaline and other factors which cloud the mind come into play. Ever seen a report of a crime by witnesses where every witness said a different storey? I have. Its not a fact, its a memory.

Kwaitek, you did flight models for UP. It alarms me you cant control yourself when I ask someone else their opinion in a forum specifically and your emotions require you to laugh at me and "state your "expert" opinion". How can you apply scientific thought when you are so easily ruled by you emotions? - I dont require an answer by the way...

Yes and do you see what I did in this thread? I analysed, I provoked, I suggested with and without belief, I theorised... -Then I made a judgement... Dont be so ignorant. Assumptions are not always right at first glance.

Ernst 05-30-2012 11:45 PM

If you repeat Ivank's experiment at least ten times for each aircraft, calculate the average climbing curves for each ones, then calculate the standard deviation around the average for both, use it as an error bar and show me that the bars do not superpose themselves I ll agree in the same time.
