Dave,
Yes, I'm well aware that the FDEs in flightsim are much less an accurate representation and much more an exercise in low cunning!
![Laughing :lol:](./images/smilies/lol.gif)
. I've done a few myself.
However, my point is that there is a significant error in the handling of this aircraft which isn't present in Robert Sanderson's previous Hurricanes; it manifests itself as a continuous nodding in pitch, without any elevator deflection (commanded or otherwise), at speeds above 250 kt or so. This is wrong.
From previous experience, I know that this authors FDEs are usually immaculate, so rather than dive into it in the way I would attack an Ito model, I looked for a possible single error.
Looking at the FDEs for the previous RS Hurricanes, and comparing them with the Mk IID (which aren't very different), I tried several ways to improve the handling by using elements of his earlier files and eventually found that the only element which completely eliminated the error was to revert to the 'earlier-used-by-RS' value for the wing area. It happens by chance to be the correct wing area for the Hurricane, but that's beside the point.
I do understand your point about 'fiddling with' the flight model, but I hope that with my 30 years experience as an aerodynamicist/aeronautical engineer and 25 years as a pilot, together with a few years of flight sim, I'm a bit beyond that
I agree that other elements of the flight envelope might be affected, as I mentioned in my first post, but I haven't found any yet.
Cheers,
Kevin
