Scaling and Comparative Analysis.
From an analytical view point, the best state of data presented in this report is the 3-d wing Cl polar. So I will use that data as the basis for a comparative analysis.
The Cl max for the in game 190 was derived by a comparison of the full scale tests at the Chalais-Meudon wind tunnel to some other sets of data. The Chalais-Meudon wind tunnel tests were conducted with a Re of 4.6e6 and yielded a Cl max of 1.3. Since the Re is still below the flight condition the Cl max had to be increased to account for the difference in Reynolds numbers. The Cl, in game, for the Fw 190 is ~ 1.39. In- game stall conditions result in a Re ~ 5.7 at a speed of 170 kph. Mach .13 The amount of Cl max added to the Chalais-Meudon wind tunnel test was based on a comparison of aircraft with similar aerofoils and some wind tunnel tests of a wing with a similar profile to the 190.
I have 3 sources that will put the Cl max of the 3-d Fw190 wing around ~ 1.5 One is a paper on a CFD analysis of world war 2 aircraft, that's been around for awhile. It contains a sectional lift distribution of the 190's wing at the 1g stall and notes the Cl max of the aircraft as 1.5.
