My learning curve tells me that the mixture issue need to be taken care of, and that the FM needs to provide us with more feedback and certain elements of aircrafts behaviour before a FM test is justified. Otherwise mapping an aircrafts performance envelope will not be correct once the FMs have been changed. They know about those issues and I'm sure they are working on it. I'll say it like this: There's no use taking a Fiat Uno to Nürburgring to test lap times, if the race is classed as a FIA GT. But by all means, if you people need something to do just for the sake of doing it......

That's useful data on early Spits, thanks.

I don't know if this ever started or how serious Viper is but I am willing to help with the testing but ONLY if there is some assurance from the development team that it is being taken seriously.
From what I am seeing wider Europe is undertaking a Public Beta test which is adhoc and incredibly disorganised. So, if we are given genuine co-operation from Luthier & friends, and that we supply genuine reliable information to them to use, then I'm signed up. |

As far as ambient conditions, either use the gauges in game and hope they are calibrated correctly, or just e-mail the developers to find out what the stock standard atmospheric conditions are. If there's a way to adjust atmospheric conditions in the FMB (I would look, but will not have my computer with COD for awhile as I'm in the States), then you could create a mission in the FMB that all testers would be compelled to use that are a part of this project. Really, the best historical data (if it exists) would be that which has variable test data, such as a curve that represents the difference in performance compared to altitude and temperature on the graph axes in order to adjust for density altitude. If this sim has variable weather as it says, then it will be hard to see if the aircraft performs correctly over a range of temps and pressures if it's only tested on a standard day.

I've also got a PhD to finish. Quote:
It's also inherently more likely to produce flame wars because if we pick a NACA atmosphere then people will see American aeroplanes with data which looks like primary source data and potentially German or British aeroplanes with corrected data which disagrees with primary sources. We would then find ourselves having to explain the concept of standard atmospheres and correction factors in the face of vociferous accusations of bias from the large population of trolls that inhabit the forum. Whatever we do, we're going to end up picking a single standard atmosphere so that we can compare the performance of all the aeroplanes in the sim on the same chart. Apart from anything else, if we don't do this, the chances are the somebody else will do so in a biased way with the intention of forwarding their own agenda, since quite a lot of forum trolls seem more interested in being able to say "my aeroplane is better than yours" than in historical accuracy. Ideally, I'd use the ISO standard atmosphere, because it's neutral and current. However, I don't think that it's freely available, and that would both interfere with testing and lead to accusations that the process was not transparent. The 1976 US standard atmosphere is freely available on the internet, and avoids most of the risk of accusations of bias it's post-war*, and it is relatively modern (so we get basically modern SI units, though it uses its own private value of the gas constant, presumably for historical reasons). *Therefore all of the aeroplanes we test will see correction factors. |

I've got some of my old university textbooks still, one of them has a standard atmosphere in the appendix; I'll check to see which version it is. The textbook is relatively new so it ought to be a modern ISO atmosphere.

Just done a quick check on the Spitfire II, on the ground at Mansten ( 178 feet) the closest I can get in 1 MB increments is a bout 993mb, at Shoreham (7 feet) on the same map 992 MB.
With the current standard SL pressure at 1013 MB it looks like theres a bit of a Low over the South East of England. Also, FTIW, from the oil temp it's about 21 Degrees. Cheers Last edited by Skoshi Tiger; 06-11-2011 at 01:43 AM. |

Let me know if that's worth anything to you and I'll see what I can do about scanning it. |
