Realism, whats missing?

[MaxGunz]

IL-2 simulates flight and does not have _all_ the real factors and motions but does cover the major aspects down to a number of minor effects.

But when near the ground the differences between the sim and reality get a bit farther apart. What ground-effect simulating there is only occurs over landing strips and covers what happens less well than could be desired.

Some of the planes seem to have too much lift at low speeds though it was worse in release versions of FB and Aces. At very high speeds the differences between the simulation and reality spread out more and more with increase in speed, effects of compression on props and airframe is not detailed giving a noticeable difference in results that many players have shown.

Even if you can find charts for a particular IL-2 model, matching down to the prop/engine/etc, the performance of IL-2 will have places that do not match.
You get in the real plane and expect to change speed or alt in a certain way then you could possibly get in trouble especially near to ground where IL-2 less fully covers effects and differences can lead to unwanted contact with the ground then what would your last words be?

Have a chance? Certainly. Maybe a good one. You might even learn something about wind socks IRL but you won't in IL-2.
