One thing to consider when comparing real-world handling qualities versus simulated handling is the control devices. I use a Logitech Gamepad which is not ideal by any means, it serves my purposes and gives me acceptable handling capability. The biggest problem with it is the small throw of the sticks which makes them very touchy. Even if you have a full size control column, you lose a lot of fidelity due to the lack of control feedback as well as lack of "seat of your pants" feedback. Both the control throw and the feedback issues result in a great loss of fidelity which makes it impossible to control an aircraft in simulation anywhere near as well as the real thing. | |||
Taking the P-51 issue as an example; even if the FDM did closely emulate the real thing, the reaction time to correct for any divergent yaw on takeoff will be much slower than it would be in real life with more sensory cues. Once you do react, you can't react with the same accuracy as real life due to the lack of control feedback, so your inputs will tend to over correct the situation which in turn you will be slower to react to. | |||
This can obviously be corrected by making the FDMs less touchy than the real-world aircraft, but this then compromises reality. So it takes a bit of a balance. | |||
First, let me say that there are HUGE fluctuations in the quality of FG flight dynamics models, and that I don't like all of them. This is why I specifically wrote which planes I use and asked which plane you've been flying. Some FDMs are pretty bad, but others (the Seneca-II for instance) are made by people who fly the real thing, yet others (the P-51D, the F-16) are done using a huge pile of available test data and have been tweaked literally for hundreds of hours to agree with the real performance and capabilities. It's these FDMs which I like and which I'm defending here. | First, let me say that there are HUGE fluctuations in the quality of FG flight dynamics models, and that I don't like all of them.
