Thanks!

It is something I have been doing offline for.. gee some 10+ years with IL-2 data.

But I wanted to make it a real time process that the user can select what data they want to look at and compare to.. Which is the goal of this website.

Thanks!

Yes, hopefully this will also help put a lot of forum arguments to rest.. When the can see the actual real world data that was used as a comparison.

A bit alarming too that the CoD machine can achieve 6000 fpm climb performance!

Ah, that is that confusing part I made a reference too

See.. right now there are only two test types.. Top Speed per Altitude (TSPA) and Rate of Climb (ROC)

The Real World Data (RWD) files I have uploaded typically contain both.. So both can be graphed at the same time. I just uploaded three RWD Spitfire tests +6, +12, and +16 that ONLY contain the TSPA data.

Where as the in-game test data files are only one or the other..

Both the TAS and ROC data is in every CoD test flight log.. But the 'WAY' the test is performed for TSPA or ROC is very different

Right now there is nothing in the pull down menu or text info box to say if the test is an ROC or a TSPA test.

So, what you did was select a CoD TSPA test I did..

So the TSPA test data is valid, but the ROC data from a TSPA test is NOT valid..

In that the way I fly a TSPA test (using real world methods) is to fly as fast as a can at a set altitude for a period of time..

Than I climb to the next altitude..

During that climb I am traveling at a much higher speed that the best climb speed for a ROC test..

Which results in a ZOOM climb between altitudes..

Which is why the ROC values are so high and NOT valid..

An ROC test is peformed differently, basically climbing at the best climb speed and keeping the accelerations during speed transitions as close to zero as posable..

I think I only have one CoD ROC test uploaded right now.. A Spitifre if I remember right? Just remember, when you are using a CoD ROC data file the TSPA values will NOT be valid!!

My plan is to add a TEST TYPE selection that will FILTER the CoD data such that you can only compare TSPA CoD tests to TSPA RWD tests, and ROC CoD tests to ROC RWD tests.

Yes I am amazed at how well some of the CoD data matches the RWD
