What i think that all these planes need a fair and deep Flight Model and expecially Performacne revision.
There are plent errors in maxium speed, climb rate, RPMs settings ( power settings) for Merlin engine, slats working, stability and controls ( expecially rudder) working. I wonder why 1C reduced speed of british fighters if before it was more close to RL data and now it is way off even for 6 1/4 lbs power. It was need mostly to correct 109 speed range. I wonder if they will manage to do it in accurate way ever? I dont even want to think what they will get in Battle of Moscow with russian planes if they have problem to get correct FM&performacne for a few BoB planes?

IMHO another thing that needs to be looked into is best climb speed. AFAIK the best speed for climb for the 109E in the sim is 270-280 kph IAS. This would be correct for the 109G, but the E's best climb rate was at 250 kph IAS.
This might sound as a small thing, but it seriously effect the climb curve. The FM calculates climb via a generic formula, where Vi=best climb is the peak and Vi= max level speed is 0. Shifting Vi=best climb to higher speed will thus reduce low speed (steep) climb performance and too low Vi= max level speed will reduce high speed climb, zoom etc. This can and does effect tactics such as climbing turns, using different climb angles etc.

A bit of a clarification, I wasn't suggesting you made your tests badly, dear Ivan!

If the relationships of lift and drag are correct in the model, it will reflect in the best rate of climb speed. Those airspeeds are listed in the appropriate Operating Handbook for the type. I would also suggest conducting saw tooth climb schedules to determine the Vy and Vx of the models in the game. |

The speeds used for these tests are those listed in the RAE test schedules so as to replicate the conditions in the test to those of the chart being used to plot the data. These speeds conform with those climb schedules in the relevant Pilots notes.
I am aware of best climb speeds Vx Vy etc and methods used to determine them. |

the 250 IAS is for sea level, it drops over altitude.
For example the Bf109T Alt - 0m's Speed IAS - 250 Alt - 1000m's Speed IAS - 243 Alt - 2000m's Speed IAS - 236 Alt - 3000m's Speed IAS - 229 Alt - 4000m's Speed IAS - 222 Alt - 5000m's Speed IAS - 215 Alt - 6000m's Speed IAS - 208 Alt - 7000m's Speed IAS - 200 So merely maintaining 250kmh for a 109 climb test is actually not its best climb. Just a thought. Last edited by 5./JG27.Farber; 05-29-2012 at 01:13 PM. |

The relative climb speeds, i.e., the difference between the climb speeds of all aircraft each other are in good agreement with RL.
Since to me there is no difference in the "fighting" aspect if the strategy used was to degrade RAF fighters or upgrade the LW ones. Obviously I prefer that the LW ones upgraded to its RL curves. But if someone is complaining that they were being shot down because the RAF are uncompetitive in climb area I disagree. |
