Fully open first, then fully closed. Trimmed nose-heavy a bit to compensate.

Redid the test 10 times at various altitudes and throttle settings.

This was ONLY with the 109 E-4 though, i'm a bit too lazy to test the other planes, but feel free to do so.

(yes, i doubted that they would forget to implement that in the "most accurate flightsim" etc., that's why i didn't believe the OP at first)

Checked the Spitfire Ia. Closing radiator definately causes an increase in airspeed there, opening radiator slows the plane down.

So i better check the 109 again.

EDIT:

OK, rechecked the E-4, it's not there. So the radiators have no effect on speed on the E-4, but they do have an effect on speed on the Spitfire Ia.

Disagree 100%

The 'point' your missing, or ignoring on purpose, is that 'rule' is in regards to, as addman pointed out BASIC AERONAUTICS! Which makes me smile when some here would suggest that Oleg is not capable of even the basics.. But I digress! Back to the point your missing.. Games are complex programs that tax every aspect of the PC hardware and software.. Just because the 1C team is having issues dealing with some nuances of a hardware driver error or OS issue does not mean 1C does not understand the basics of aerodynamics.

How did you know I named it ego? But I digress.. I can see your still missing the point here, so allow me to point this out to you again

BASIC AERODYNAMICS

Now I challenge you to go get that 'list' your referring to and out all the things fixed count up the items that fall into the category of BASIC AERODYNAMICS vs Video driver issues, GUI fixes, CTD, etc etc etc and than maybe.. just maybe even a die hard biased stood up on prom night 'swell fella' like yourself will see how ludicrous it is to even suggest that 1C does not have a grasp on BASIC AERODYNAMICS

Well like I said from the start..

To come to the conclusion I came to on this subject.. It requires a 'reasonable' man.. hint hint

I think you will have great difficulty testing this without logging data. I think they have modeled wind. Also, they may have also modeled analog stuttering in the gauges, so your reading is always going to be off within some tolerance if that is the case. Also, different planes will no doubt be impacted by different designs. Some planes you may notice the effect and others, not so much. I think of the 190 in 46', I don't really notice much when rad is open or closed, but 109 I definitely do and actually use open rad to burn speed. Anyway, if there is a way to turn off the wind in the CLoD testing, that would be a good idea.

There is another post by FHT the cowboy guy in fmb section. He made black box script to log data. Maybe you could use that. I would do this test at sea level over the ocean, maybe 50-100 meters. Run the plane up to cruising speed settings with rad full open. Hold it there in level flight and trim. Then toggle the rads closed. Since the rads are modeled separately, then you can do the test for both rad types independently and together to see the different effects. It wouldn't surprise me if this piece got dropped because...Oleg left. He definitely cared about flight models and quality products. But he is working a new job now.

How is wind going to affect any test. IAS is not wind affected ... (unless you are stationary on the ground

if it is variable in speed and direction, it will have an impact on your TAS/IAS at any moment in time. correct???

No. Wind will affect Ground speed but has zero effect on IAS and TAS.

Why ? again wind has no effect on IAS or TAS.

MadBlaster · #**149** 11-03-2011, 01:19 AM

So I suppose the jet stream means nothing to you. No effect on TAS what so ever.

IvanK · #**150** 11-03-2011, 01:38 AM

Err I ride jetstreams for a living

they don't affect TAS just the Groundspeed.

Whether I am in the jetstream or not the Mach number and or IAS and the TAS are the same, the Groundspeed changes though. If i was in the centre of a jetsream and performed a 180degree turn all that changes is groundspeed, IAS/TAS and Mach number remain the same.
