I think it may be beneficial if we all chose something different to test and then share the results. Tests usually are done with the following: -Crimea map -12:00 o'clock PM -Test performed over water I would like some ideas as to what we could test. Here are a few: -Speeds of various aircraft at differing altitudes. One person could test speeds at 2,000m, another at 4,000m, etc. -Critical dive speeds, could be started at 5,000m using a shallow dive and indicated air-speed used to determine break-up point. -Turn test, could be done by two people online. Planes flown against each-other and turn-rates tested. -Control stiffness, planes flown to designated speed(s) and rated from 1 to 10 in terms of control stiffness. This has important effects on tactics. Please offer any other ideas that come to mind. This could be done over a long period of time and the results simply added to as they are determined. We can discuss this in more detail when we get together on TS. Finally, it would be great if we could post the results in a password protected room : .

For example here are Stecher's SL speed test results:

Stecher, what are the two speeds? Are they for different altitudes or different engine tests, or is the change due to acceleration?

All speeds were taken at sea level. Max continuous was reached by setting the throttle to 100% with the radiator closed. Prop pitch was either 100% or automatic when available, whichever yielded a higher speed. And on Russian planes fuel mix was set to 100%. The WEP speeds were obtained by simply going all out and disregarding engine overheating. Radiator setting, prop pitch, and fuel mix were same as before, but throttle was 110% with boost enabled if available. IAS (indicated air speed) is what the gauges show, and TAS (true air speed) is how fast you are actually going.

-Control stiffness, planes flown to designated speed(s) and rated from 1 to 10 in terms of control stiffness. This has important effects on tactics. S~ everyone, I've been trying to think of a better way to do this. rating the response from 1 - 10 is too subjective for me. For example if a 190 pilot and a109 pilot test the same plane, the 190 pilot will be a lot harder on the high speed elevator and aileron response than a 109 pilot will. Aileron response is pretty easy, just set the speed an altitude and then get the time it takes to roll 360 degrees. For elevator response this is what I came up with. * Switch cockpit to wonder woman view (stick with me I know its sacriligeous but it helps a great deal) The ariticialy horizon in this view is graduated. Most of the planes in the sim don't have this. I believe the graduations go from -45* to +45* with respect to the horizon. * Point the plane at -45* wait till you reach a certain speed (I tested from 300 - 850) * Start stop watch * Pull back till you reach +45* * Record time * rinse repeat The problem is its very hard to stay within a certain altitude range when diving at such high speeds. If any one has some good ideas how to do this. Best idea I have is to use projectile physics to determine a starting altitude. It will get you in the vicinity, but since the wing generates lift at higher speed this value may be off by quite a bit. Here's a couple graphs of a p38j vs 109g6/as This one is zoomed in
